LTC2951-2 Datasheet | Linear Technology

FEATURES Adjustable Push Button Debounce and Delay Timers - Low Supply Current: 6µA - Wide Operating Voltage Range: 2.7V to 26V - EN Output (LTC2951-1) Allows DC/DC Converter Control - ⎯E⎯N Output (LTC2951-2) Allows Circuit Breaker .. Control - Simple Interface Allows Graceful µP Shut Down - High Input Voltage ⎯P⎯B Pin with Internal Pull Up Resistor - ±10k V ESD HBM on ⎯P⎯B Input - Accurate 0.6V Threshold on ⎯K⎯I⎯L⎯L parator Input - 8-Pin 3mm × 2mm DFN and Thin SOTTM Packages - DESCRIPTIO The LTC®2951 is a micropower, wide input voltage range push button ON/OFF controller. The part contains a push button input which controls the toggling of an open drain enable output. The push button turn OFF debounce time is externally programmable, while the turn ON debounce time is fixed at 128ms. A simple microprocessor interface allows for proper system housekeeping prior to power down. Under system fault conditions, an adjustable ⎯K⎯I⎯L⎯L timeout delay ensures proper power down.
