| FDG6331L April 2001 FDG6331L Integrated Load Switch General Description This device is particularly suited for compact power management in portable electronic equipment where 2.5V to 8V input and 0.8A output current capability are needed. This load switch integrates a small N-Channel power MOSFET (Q1) that drives a large P-Channel power MOSFET (Q2) in one tiny SC70-6 package. Features * -0.8 A, -8 V. RDS(ON) = 260 m @ VGS = -4.5 V RDS(ON) = 330 m @ VGS = -2.5 V RDS(ON) = 450 m @ VGS = -1.8 V Applications * Power management * Load switch * Control MOSFET (Q1) includes Zener protection for ESD ruggedness (>6KV Human body model) * High performance trench technology for extremely low RDS(ON) * Compact industry standard SC70-6 surface mount package Q2 Equivalent Circuit 3 2 Q1 Vin,R1 ON/OFF R1,C1 4 5 6 Vout,C1 IN Vout,C1 R2 + V DROP - OUT 1 See Application Circuit Pin 1 ON/OFF SC70-6 Absolute Maximum Ratings Symbol VIN VON/OFF ILoad PD TJ, TSTG Gate-Source Voltage (Q2) Gate-Source Voltage (Q1) Load Current - Continuous - Pulsed Maximum Power Dissipation TA=25oC unless otherwise noted Parameter Ratings 8 -0.5 to 8 (Note 2) (Note 2) (Note 1) Units V V A W C -0.8 -2.4 0.3 -55 to +150 Operating and Storage Junction Temperature Range Thermal Characteristics RJA Thermal Resistance, Junction-to-Ambient (Note 1a) 415 C/W Package Marking and Ordering Information Device Marking .31 Device FDG6331L Reel Size 7'' Tape width 8mm Quantity 3000 units 2001 Fairchild Semiconductor Corporation FDG6331L Rev B(W) FDG6331L Electrical Characteristics Symbol BVIN ILoad IFL IRL TA = 25C unless otherwise noted Parameter Vin Breakdown Voltage Zero Gate Voltage Drain Current Leakage Current, Forward Leakage Current, Reverse (Note 2) Test Conditions VON/OFF = 0 V, ID = -250 A VIN = -6.4 V, VON/OFF = 0 V VON/OFF = 0 V, VIN = 8 V VON/OFF = 0 V, VIN = -8 V VIN = VON/OFF, ID = -250 A VIN = 4.5 V, VIN =2.5 V, VIN = 1.8 V, VIN = 4.5 V, VIN = 2.7 V, ID = -0.8 A ID = -0.7 A ID = -0.6 A ID = 0.4A ID = 0.2 A Min 8 Typ Max Units V -1 100 -100 A nA nA Off Characteristics On Characteristics VON/OFF (th) RDS(on) Gate Threshold Voltage Static Drain-Source On-Resistance (Q2) Static Drain-Source On-Resistance (Q1) 0.4 0.9 155 193 248 310 380 1.5 260 330 450 400 500 -0.25 -1.2 V m RDS(on) m Drain-Source Diode Characteristics and Maximum Ratings IS VSD Maximum Continuous Drain-Source Diode Forward Current Drain-Source Diode Forward Voltage VON/OFF = 0 V, IS = -0.25 A(Note 2) A V Notes: 1. RJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of the drain pins. RJC is guaranteed by design while RJA is determined by the user's board design. 2. Pulse Test: Pulse Width < 300s, Duty Cycle < 2.0%.
