The core is a 12 mΩ P-channel MOSFET and controller capable of functioning over a wide input operating range of 2.3 V to 5.5 V. The ONB pin, active-LOW; controls the state of the switch. RCB functionality blocks unwanted reverse current during OFF states by power switch isolation between PWRA and PWRB. Reverse-Current Blocking The reverse-current blocking feature protects the input source against current flow from output to input when the load switch is off by changing the internal body diode direction. Bypass Capacitor To limit the voltage drop on the input supply caused by transient inrush current when the switch turns on into a discharged load capacitor; a capacitor must be placed between the PWRA or PWRB and GND pins. A ceramic capacitor of at least 1 µF placed close to the pins is usually sufficient. Inrush Current Inrush current occurs when the device is turned on. Inrush current is dependent on output capacitance and slew rate control capability, as expressed by: I INRUSH COUT where: COUT: tR: VIN: VINITIAL: ILOAD: Board Layout VIN VINITIAL I LOAD tR For best performance, all traces should be as short as possible. To be most effective, the input and output capacitors should be placed close to the device to minimize the effect that parasitic trace inductance on normal and short-circuit operation. Using wide traces or large copper planes for all pins (PWRA, PWRB, ONB, and GND) minimizes the parasitic electrical effects and the case-to-ambient thermal impedance. Output capacitance; Slew rate or rise time at VOUT; Input voltage; Initial voltage at COUT, usually GND; and Load current. Higher inrush current causes higher input voltage drop, depending on the distributed input resistance and input capacitance. High inrush current can cause problems. FPF2411 has a 3 ms of slew rate capability under 4.2 VIN at 1 µF of COUT and 10 Ω of RL. Inrush current can be minimized and no input voltage drop appears, as shown in Figure 16. © 2015 Fairchild Semiconductor Corporation FPF2411 • Rev. 1.7 FPF2411 — IntelliMAX™ 6 V / 6 A-Rated Bi-Direction Switch with Slew-Rate Control Operation and Application Description www.fairchildsemi.com 9 FPF2411 — IntelliMAX™ 6 V / 6 A-Rated Bi-Direction Switch with Slew-Rate Control © 2015 Fairchild Semiconductor Corporation FPF2411 • Rev. 1.7 www.fairchildsemi.com 10 FPF2411 — IntelliMAX™ 6 V / 6 A-Rated Bi-Direction Switch with Slew-Rate Control © 2015 Fairchild Semiconductor Corporation FPF2411 • Rev. 1.7 www.fairchildsemi.com 11 0.03 C E 2X F A (Ø0.215) Cu Pad 1.20 B 0.80 PIN 1 AREA D 0.40 12X 0.20 0.03 C TOP VIEW RECOMMENDED LAND PATTERN (NSMD PAD TYPE) 2X 0.378±0.018 0.208±0.021 0.625 0.547 0.05 C C (Ø0.315) Solder Mask SEATING PLANE D SIDE VIEWS NOTES: A.
