On/Off Controller with Debounce and
±15kV ESD Protection
General DescriptionFeatures
The MAX16054 is a pushbutton on/off controller with a
single switch debouncer and built-in latch. It accepts a

Ordering Information
Undervoltage-lockout circuitry ensures that OUT is in the
off state upon power-up. The MAX16054 requires no
external components, and its low supply current makes
