FPF3042: IntelliMAX™ 18 V-Rated Dual Input Single Output Power-Source-Selector Switch

The FPF3042 is an 18 V-rated Dual-Input Single-Output (DISO) load switch consisting of two channels of slew-rate-controlled, low-on-resistance, N-channel MOSFET switches 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 4.0 V to 12.4 V at both VBUS and VIN to align with the needs of high-voltage portable device power rails.

Both VIN and VBUS have the over-voltage protection of 14 V (typical) to avoid damage to the system.

VIN and VBUS bidirectional switching allows reverse current from VOUT to VIN or VBUS for On-The-Go, (OTG) Mode. The switching is controlled by logic input EN and VIN_SEL is capable of interfacing directly with low-voltage control signal General-Purpose Input / Output (GPIO).

FPF3042 is available in 1.76 mm x 1.96 mm Wafer-Level Chip-Scale Package (WLCSP), 16-bump, 0.4 mm pitch.
