RS31325
Two Channels 2.95V to 16V Power MUX with Priority Selection
Features
The RS31325 power mux is a dual input, single output device with low quiescent current and low Ron resistance. The wide operating input range allows the device to be used in many DC bus voltage applications.
With individual enable pin for both channels, the device can select and seamlessly transit between available input sources. With back-to-back MOSFETs design for both channels, the device blocks reverse current during switchover.
The device has fast input switchover capability to reduce the potential output voltage drop during switchover, which allows less output capacitors to be used in the system.
The device has adjustable over-current protection, input UV and OV protection, and over-temperature protection.
The device is available in LGA-25, 4×4 mm package.
