onsemi FPF3042UCX

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.
