The LTC2952 is a power management device that features three main functions: push-button on/off control of system power, ideal diode power path control, and system monitoring. The LTC2952’s push-button 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 that allows for proper system housekeeping prior to power down. The ideal diode power paths 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.
