SMH4803 Overview
The SMH4803 hot-swap controller provides under-voltage and over-voltage monitoring of the host power supply, it drives an external power MOSFET switch that connects the supply to the load, and also protects against over-current conditions that might disrupt the host supply. When the input and output voltages to the SMH4803 controller are within specification, the SMH4803 provides three “Power Good” logic outputs...
