The FPF2213-FPF2215 are low RDS(ON) P-Channel MOSFET load switches with high precision current limit value. The input voltage range operates from 1.8V to 5.5V to fulfill today's Ultra Portable Device's supply requirement. Switch control is by a logic input (ON) capable of interfacing directly with low voltage control signal. On-chip pull-down is available for output quick discharge when switch is turned off. For the FPF2214, if the constant current condition still persists after 30ms, these parts will shut off the switch and pull the fault signal pin (FLAGB) low. The FPF2213 has an auto-restart feature, which will turn the switch on again after 450mS if the ON pin is still active. The FPF2214 do not have this auto-restart feature so the switch will remain off until the ON pin is cycled. For the FPF2215, a current limit condition will immediately pull the fault signal pin low and the part will remain in the constantcurrent mode until the switch current falls below the current limit. For the FPF2213 through FPF2215, the current limit is set by an external resistor and the minimum current limit is 100mA.

FPF2213-FPF2215 Integrated Load Switch with Adjustable High Precision Current Limit
Description of Operation
The FPF2213, FPF2214, and FPF2215 are state of the art Adjustable High Precision Current Limit switches that protect systems and loads which can be damaged or disrupted by the application of high currents. The core of each device is a 0.27 P-channel MOSFET and a controller capable of functioning over an input operating range of 1.8V - 5.5V. The controller protects offers current limiting, UVLO(undervoltage lockout) and thermal shutdown protection. The current limit is adjustable from 100mA to 250mA through the selection of an external resistor.
Undervoltage Lockout (UVLO)
The undervoltage lockout turns-off the switch if the input voltage drops below the undervoltage lockout threshold. With the ON pin active the input voltage rising above the undervoltage lockout threshold will cause a controlled turn-on of the switch which limits current over-shoots.
Output Discharge Resistor
The FPF2213/4/5 family contains an 80 on-chip load resistor for quick output discharge when the switch is turned off. This features become more attractive when application requires large output capacitor to be discharge when the switch tunrs off. However, VOUT pin should not be connected directly to the battery source due to the discharge mechanism of the load switch.
On/Off Control
The ON pin is active high, and controls the state of the switch. Applying a continuous high signal will hold the switch in the on state. The switch will move into the OFF state when the active high is removed, or if a fault is encountered. For all versions, an undervoltage on VIN or a junction temperature in excess of 140C overrides the ON control to turn off the switch. In addition, excessive currents will cause the switch to turn off in the FPF2213 and FPF2214. The FPF2213 has an Auto-Restart feature which will automatically turn the switch on again after 450ms. For the FPF2214, the ON pin must be toggled to turn-on the switch again. The FPF2215 does not turn off in response to an over current condition but instead remains operating in a constant current mode so long as ON is active and the thermal shutdown or UVLO have not activated.
Thermal Shutdown
The thermal shutdown protects the die from internally or externally generated excessive temperatures. During an overtemperature condition the FLAGB is activated and the switch is turned-off. The switch automatically turns-on again if temperature of the die drops below the threshold temperature.
Fault Reporting
Upon the detection of an over-current condition, an input UVLO, or an over-temperature condition, the FLAGB signals the fault mode by activating LO. In the event of an over-current condition for the FPF2213 and FPF2214, the FLAGB goes LO at the end of the blanking time while FLAGB goes LO immediately for the FPF2215. If the over-current condition lasts longer than blanking time, FLAGB remains LO through the Auto-Restart Time for the FPF2213 while for the FPF2214, FLAGB is latched LO and ON must be toggled to release it. With the FPF2215, FLAGB is LO during the faults and immediately returns HI at the end of the fault condition. FLAGB is an open-drain MOSFET which requires a pull-up resistor between VIN and FLAGB. During shutdown, the pull-down on FLAGB is disabled to reduce current draw from the supply. A 100K pull up resistor is recommended to be used in the application.
Current Limiting
The current limit ensures that the current through the switch doesn't exceed a maximum value while not limiting at less than a minimum value. The current at which the parts will limit is adjustable through the selection of an external resistor connected to the ISET pin. Information for selecting the resistor is found in the Application Information section of this datasheet. The FPF2213 and FPF2214 have a blanking time of 30ms (nominal) during which the switch will act as a constant current source. At the end of the blanking time, the switch will be turned-off. The FPF2215 has no current limit blanking period so it will remain in a constant current state until the ON pin is deactivated or the thermal shutdown turns-off the switch.

FPF221X family has 5% precision at higher load current. The ILIM (Max) and tolerance of current limit value can be determined using Figure 21 (ILIM vs RSET ) and the following formula: ILIM (Typ) - ILIM (Min) ILIM (Typ)
To limit the voltage drop on the input supply caused by transient in-rush currents when the switch is turned on into a discharged load capacitor or a short-circuit, a capacitor is recommended to be placed between VIN and GND. A 1uF ceramic capacitor, CIN, placed close to the pins is usually sufficient. Higher values of CIN can be used to further reduce the voltage drop.
Input Capacitor
Output Capacitor
Tolerance (%) = 100 * A 0.1uF capacitor COUT, should be placed between VOUT and GND. This capacitor will prevent parasitic board inductances from forcing VOUT below GND when the switch turns-off. For the FPF2213 and FPF2214, the total output capacitance needs to be kept below a maximum value, COUT(max), to prevent the part from registering an over-current condition and turning-off the switch. The maximum output capacitance can be determined from the following formula: COUT (Max) = Tol [%] 5.0 5.4 5.7 5.8 6.4 7.5 8.5 11.1 15.0 If the part goes into current limit, maximum power dissipation will occur when the output is shorted to ground. For the FPF2213, the power dissipation will be scaled by the AutoRestart Time, tRSTRT, and the Over Current Blanking Time, tBLANK. Therefore, the maximum power dissipated is: tBLANK tBLANK + tRSTRT 30 30 + 450 ILIM (Max) * tBLANK (Min) VIN
ILIM (Max) =
I * Tolerance (%) ILIM (Typ) + LIM (Typ) 100

During normal on-state operation, the power dissipated in the device will depend upon the level at which the current limit is set. The maximum allowed setting for the current limit is 250mA and will result in a power dissipation of: P = (ILIM)2 * RDS = (0.25)2 * 0.275 = 17mW

FPF2213-FPF2215 Integrated Load Switch with Adjustable High Precision Current Limit
Take note that this is below the maximum package power dissipation, and the thermal shutdown feature will act as additional safety to protect the part from damage due to excessive heating. The junction temperature is only able to increase to the thermal shutdown threshold. Once this temperature has been reached, toggling ON will not turn-on the switch until the junction temperature drops. For the FPF2215, a short on the output will cause the part to operate in a constant current state dissipating a worst case power of: P (Max) = VIN (MAX) * ILIM (MAX) = 5.5 * 0.276 = 1.5W This large amount of power will activate the thermal shutdown and the part will cycle in and out of thermal shutdown so long as the ON pin is active and the short is present.
The following techniques have been identified to improve the thermal performance of this family of devices. These techniques are listed in order of the significance of their impact. 1. Thermal performance of the load switch can be improved by connecting pin7 of the DAP (Die Attach Pad) to the GND plane of the PCB. 2. Embedding two exposed through-hole vias into the DAP (pin7) provides a path for heat to transfer to the back GND plane of the PCB. A drill size of Round, 14 mils (0.35mm) with 1-ounce copper plating is recommended to result in appropriate solder reflow. A smaller size hole prevents the solder from penetrating into the via, resulting in device lift-up. Similarly, a larger via-hole consumes excessive solder, and may result in voiding of the DAP.
PCB Layout Recommendations
In order to benefit from adjustable, high-precision load switch devices, a high-precision RSET value must be used to set a tight current limit tolerance. Since ILIMIT (current limit value) is determined by the voltage drop across the RSET, a poor PCB layout can introduce parasitic noise on the ISET pin resulting in a minor variation of ILIMIT. To improve the ILIMIT stability, parasitic noise coupling mechanisms from ISET to GND must be minimized. This becomes more critical when ILIMIT is set close to the nominal load current operation where parasitic effects could cause the device to go in and out of current limit and result in an error flag report. Care must be taken to provide a direct current return path between the RSET ground pad and the device ground pad (pin5). Please see current pad #2 in figure below. Figure 23: Two through hole open vias embedded in DAP
1)Power current path 2)RSET current path Figure 22: Eliminate parasitic noise of ISET-GND by providing a separate ground route, unique from the power ground plane
Figure 24: X-Ray result (bottom view with 45o angle) 3. The VIN, VOUT and GND pins will dissipate most of the heat generated during a high load current condition. Using wide traces will help minimize parasitic electrical effects along with minimizing the case to ambient thermal impedance. The layout suggested in Figure 25 provides each pin with adequate copper so that heat may be transferred as efficiently as possible out of the device. The low-power FLAGB and ON pin traces may be laid-out diagonally from the device to maximize the area available to the ground pad. Placing the input and output capacitors as close to the device as possible also contributes to heat dissipation, particularly during high load currents.
Improving Thermal Performance
An improper layout could result in higher junction temperature and triggering the thermal shutdown protection feature. This concern applies when the switch is set at higher current limit value and an over-current condition occurs. In this case, the power dissipation of the switch, from the formula below, could exceed the maximum absolute power dissipation of 1.2W. PD = (VIN - VOUT) x ILIM (Max)
