MAX5943 Datasheet (Maxim Integrated Products) - FireWire Current Limiter and Low-Drop ORing Switch Controller

MAX5943, FireWire Current Limiter and Low-Drop ORing Switch Controller

The MAX5943 is a fully integrated power-management IC for FireWire® applications.

This device controls two external power n-channel MOSFETs to regulate current from the input power supply to the load and performs low-voltage-drop, power-supply ORing.

The MAX5943 operates over a 7.5V to 37V input ran

MAX5943 Features

* a current-limit function that actively limits the current drawn by the load with a programmable timeout. The MAX5943B

* MAX5943E do not actively limit the load current but provide a circuit-breaker function. See the Selector Guide for the default and programmable circuit-breaker timeouts. The
