Description

The FPF2411 is a 6 V / 6 A-rated bi -directional load switch, consisting of a slew -rate-controlled, low -on- resistance, P-channel MOSFET switch with protection features. The slew -rate-controlled turn -on characteristic prevents inrush current and the resulting excessive voltage droop on the input power rails. The input voltage range operates from 2.3 V to 5.5 V. Bi-directional switching allows reverse current from V OUT to V IN. The switching is controlled by active -LOW logic input the ONB pin. The FPF2411 is capable of interfacing directly with low -voltage control signa l General-Purpose Input / Output (GPIO). The FPF2411 is available in 12-bump, 1.235 mm x 1.625 mm Wafer-Level Chip -Scale Package ( WLCSP) with 0.4 mm pitch.

© 2015 Fairchild Semiconductor Corporation www.fairchildsemi.com FPF2411 • Rev. 1.7 9 FPF2411 — IntelliMAX™ 6 V / 6 A-Rated Bi-Direction Switch with Slew-Rate Control Operation and Application Description The FPF2411 is an ultra-low-RON P-channel load switch with bi-directional controlled turn -on and Reverse Current Blocking (RCB). 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 rev erse current during OFF states by power switch isol ation between PWRA and PWRB. Inrush Current Inrush current occurs when the device is turned on. Inrush current is depend ent on output capacitance and slew rate control capability, as expressed by: LOAD R INITIALIN OUTINRUSH It VVCI  where: COUT: Output capacitance; tR: Slew rate or rise time at VOUT; VIN: Input voltage; VINITIAL: Initial voltage at COUT, usually GND; and ILOAD: 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 C OUT and 10 Ω of R L. I nrush current can be minimized and no input voltage drop appears, as shown in Figure 16. 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 curre nt 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 a t least 1 µF placed close to the pins is usually sufficient. Board Layout For best performance, all tra ces 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 , ON B, and GND) minimize s the parasitic electrical effects and the case-to-ambient thermal impedance.
