Fairchild/ON Semiconductor FPF3488UCX

Description
The FPF3488 is a Single Input Dual Output (SIDO) power switch that provides surge protection and Over-Voltage Protection (OVP) to protect downstream components and enhance overall system robustness.
Channel one (Veus to Vour) is an active-low, 28 V/3.5 A rated, power MOSFET switch with an internal clamp supporting ±100 V surge protection, fixed OVP at 13.9 V ( 400 mV). Channel two (Veus to SYS) is an active-high, 6 V/6 A rated, power MOSFET, fixed OVP at 5.25 V ( 250 mV) and Reverse Current Blocking (RCB) during its OFF State.
POK is paired with always ON LDO to power downstream devices when VBUS is greater than 2.7 V, regardless of OVLO, EN1, and EN2 State. This provides system power supply without battery.
The FPF3488 is available in a 28-bump, 1.67 mm x 2.96 mm Wafer-Level Chip-Scale Package (WL-CSP) with 0.4 mm pitch.
