| FDC6901L May 2002 FDC6901L Integrated Load Switch General Description This device is particularly suited for compact power management. In portable electronic equipment where 2.5V to 6V input capability is needed. This load switch integrates a Slew Rate Control Driver that drives a P-Channel Power MOSFET in one tiny SuperSOT-6 package. The integrated slew rate control driver is specifically designed to control the turn on of the P-Channel MOSFET in order to limit the inrush current in battery switching applications with high capacitance loads. For turn-off, the IC pulls the MOSFET gate up quickly. Features * * * * * * Three programmable slew rates Reduces inrush current Minimizes EMI Normal turn-off speed Low-power CMOS operates over wide voltage range High performance trench technology for extremely low RDS(ON) Applications * * Load switch Power management D2 S1 D1 G2 SuperSOT Pin 1 TM -6 S2 G1 SuperSOTTM-6 Absolute Maximum Ratings Symbol VDD VIN PD TSTG TA=25oC unless otherwise noted Parameter Supply Voltage DC Input Voltage (Logic Inputs) Power Dissipation Storage Junction Temperature Range Ratings -0.5 to 10 -0.7 to 6 -55 to +150 Units V V C Recommended Operating Range VDD TJ Supply Voltage Operating Junction Temperature -0.5 to 10 -55 to +150 V C Thermal Characteristics RJA RJC Thermal Resistance, Junction to Ambient Thermal Resistance, Junction to Case 180 60 C/W C/W Package Marking and Ordering Information Device Marking .901 Device FDC6901L Reel Size 7" Tape Width 8mm Quantity 3000 units 2002 Fairchild Semiconductor Corporation FDC6901L Rev C (W) Electrical Characteristics Symbol Parameter TA=25oC unless otherwise noted FDC6901L Test Conditions Min 75%* VDD Typ Max Units Logic Levels VIH VIL Logic HIGH Input Voltage Logic LOW Input Voltage VDD = 2.7 V to 6.0 V VDD = 2.7 V to 6.0 V V 25%* VDD V OFF Characteristics - Slew Rate Control Driver BVDG BVSLEW BVIN IRDG IRSLEW IRIN Supply Input Breakdown Voltage Slew Input Breakdown Voltage Logic Input Breakdown Voltage Supply Input Leakage Current Slew Input Leakage Current Logic Input Leakage Current IDG = 10 A, VIN = 0 V, VSLEW = 0 V ISLEW = 10 A, VIN = 0 V IIN = 10 A, VSLEW = 0 V VDG = 8 V, VIN = 0 V, VSLEW = 0 V VSLEW = 8 V, VIN = 0 V VIN = 8 V, VSLEW = 0 V 9 9 9 100 100 100 V V V nA nA nA OFF Characteristics - Slew Rate Control Driver + P-Channel MOSFET BVIO IRIO IO Breakdown Voltage IO Leakage Current ID = -250 A VR = 16 V 9 100 V nA ON Characteristics - Slew Rate Control Driver IG Output/Gate Current VIN = 6V VGATE = 2V Slew Pin = OPEN = GROUND = VDD -0.6 90 1 10 -1.0 120 170 160 130 105 110 3 -1.5 145 210 300 300 180 210 A A nA V m m mV mV m m A ON Characteristics - P-Channel MOSFET VGS(th) RDS(ON) Gate Threshold Voltage Static Drain-Source On Resistance Dropout Voltage Load switch On Resistance Load Current VDS = VGS , ID = -250 A VGS = -4.5 V, ID = -1.5 A VGS = -2.5 V, ID = -1.2 A VDD = 6V, VIN = 2.5V to 6V, IL = 1.5 A VDD = 6V, VIN = 2.5V to 6V, IL = 1.2 A VDD = 6V, VIN = 2.5V to 6V, IL = 1.5 A VDD = 6V, VIN = 2.5V to 6V, IL = 1.2 A VGS = 2.5 V, VDS = 6 V ON Characteristics - Slew Rate Control Driver + P-Channel MOSFET VDROP RON ILOAD P-Channel MOSFET Switching Times Vsupply = 5.5V, VDD = 5.5V, Logic IN = 5.5V, ILOAD = 1.5A Output Turn-On Delay Time Slew Pin = OPEN tdon = GROUND = VDD trise Output Rise Time Slew Pin = OPEN = GROUND = VDD dv/dt Output Slew Rate Slew Pin = OPEN = GROUND = VDD 6.20 42 115 6.75 124 162 600 41 24 s s s s s s V/ms V/ms V/ms FDC6901L Rev C (W) FDC6901L Typical Characteristics 220 VDD = 6V VIN = 2.55V to 6V 450 400 VDD = 6V VIN = 2.55V to 6V Dropout Voltage, VDrop (mV) Dropout Voltage, VDrop (mV) 200 IL = 1.5A 350 300 250 200 150 100 50 TJ = 25 C o 180 160 IL = 1.2A TJ = 125 C o 140 120 100 -50 -25 0 25 50 75 o 100 125 150 0 0 1 2 3 Junction Temperature, C Load Current, Amps (A) Figure 1.
