The FPF2488 features a 2-channel power switch, which offers surge protection and Over-Voltage Protection (OVP), to protect downstream components and enhancing overall system robustness.
Channel one (VBUS) is an active-low, 28 V/2.5 A rated, power MOSFET switch with an internal clamp supporting ±100 V surge protection, highly accurate fixed OVP at 10.0 V (± 100 mV), and OTG functionality. Channel two (VIF) is a conditional active-high, 6 V/6 A rated, power MOSFET switch with an integrated TVS supporting ± 40 V surge protection and fixed OVP at 5.25 V (± 250 mV). VIF also provides Reverse Current Blocking (RCB) during its OFF state to minimize leakage current.
VBUS_DET is paired with always ON LDO to power downstream devices even with VBUS is greater than 2.5 V, even when disabled through the ONB pin. This provides power sequence control or a host controlled configuration in system.
The FPF2488 is available in a 15-bump, 1.6 mm x 2.2 mm Wafer-Level Chip-Scale Package (WLCSP) with 0.4 mm pitch.
