Introduction

A power-distribution switch with some protection functions. The device incorporates a N channel MOSFET power switch that is controlled by an enable logic pin and has a SS pin dedicated to soft start ramp-up rate control that can be used in application where the inrush current is concerned.

The device integrates some protection features, including current-limit protection, short-circuit protection, overtemperature protection, and UVLO. The current-limit and short-circuit protection can protect down-stream devices from catastrophic failure by limiting the output current at current-limit threshold during over-load or short-circuit events. When VOUT drops below VIN - 1V, the devices limit the output current to a lower and safe level. The overtemperature protection function shuts down the N-channel MOSFET power switch when the junction temperature rises beyond 150°C and will automatically turns on the power switch when the temperature drops by 50°C. The UVLO function keeps the power switch in off state until there is a valid input voltage present. The current limit can be set by connecting resistor from the current limit adjustable pin ISET to ground.

The device is available in lead free SOP - 8P and TDFN2x2 - 6 packages.
