Product Overview

The LTC2952IUF#PBF is a Power Management Device features three main functions of pushbutton on/off control of system power, ideal diode PowerPath™ controller and system monitoring. The LTC2952's pushbutton input, which provides on/off control of system power, has independently adjustable ON and OFF debounce times. A simple microprocessor interface involving an interrupt signal allows for proper system housekeeping prior to power-down. The ideal diode PowerPath controllers provide automatic low loss switchover between two DC sources by regulating two external P-channel MOSFETs to have a small 20mV forward drop. High reliability systems may utilize the LTC2952's monitoring features to ensure system integrity. These features includes power-fail, voltage monitoring and µP watchdog. The LTC2952 operates over a wide operating voltage range to accommodate a large variety of input power supplies.
