Surge and Over-Voltage Protection Switch for VBUS

The FPF2188L features a surge and over voltage protection switch for power path in USB type C/PD applications. The FPF2188L has Single Input Single Output (SISO) power path. Power path (VBUS to VOUT) is an active−low, 28 V / 6 A rated, power MOSFET switch with an internal clamp supporting surge protection, selectable OVP by GPIO. BUSDET is paired with always ON LDO to power downstream devices when VBUS is greater than 3.1 V, regardless of OVLO and ENB State. This provides system power supply without battery. The FPF2188L features OTGDET pin to supply the device when OTG device is inserted. It will support to turn on the power MOSFET even when VBUS voltage is low. The FPF2188L has active discharge path at VBUS which can meet USB type C w/ PD compliance. The FPF2188L is available in a 20−bump, Wafer−Level Chip−Scale Package (WL−CSP) with 0.4 mm pitch.
