LTC2955IDDB-1

Power Supply Controllers, Monitors Overview

The LTC2955IDDB-1 is a micro-power push-button on/off controller manufactured by Analog Devices Inc. It manages system power by generating a clean enable output derived from supply monitor inputs and debounced push-button signals. The device operates within an input voltage range of 1.6 V to 36 V. It features a low operating supply current of 1.2 uA, ensuring minimal energy consumption during standby states. The component is housed in a DFN-10 package and is designed for surface mount installation.
