LTC2953 - Push Button On/Off Controller With Voltage Monitoring

The LTC2953 is a push button On/Off controller that manages system power via a push button Interface An enable output toggles system power while an interrupt output provides debounced push button status. The interrupt output CAN be used in menu driven applications to request a system power down.
The LTC2953 also features input and output power supply monitors. An uncommitted power fail Comparator provides real time input monitor information, while a de-glitched under voltage lockout Comparator gracefully initiates a system power down. The under voltage lockout Comparator prevents the system from powering from a low power supply.
The adjustable supply monitor input is compared against an accurate internal 0.5V reference. The reset output remains low until the supply monitor input has been in compliance for 200ms.
The LTC2953 operates over a wide 2.7V to 27V input voltage range and draws only 14A of current. Two versions of the part accommodate either positive or negative enable polarities.
