LTC2955CDDB-2

Power Supply Controllers, Monitors Overview

The LTC2955CDDB-2 is a micropower push-button on/off controller manufactured by Analog Devices Inc. It manages system power by generating a clean enable output from supply monitor and debounced button inputs. The device features an active-low enable output (EN) suitable for controlling regulators or P-channel MOSFETs. It includes an open-drain interrupt output to signal button or low-power events. The IC supports a wide input voltage range of 1.5V to 36V and offers robust ESD protection on the button input. It operates within a temperature range of -40°C to +85°C.

Power Supply Controllers, Monitors Feature Summary

• Generates clean enable outputs from supply monitor and debounced push-button inputs
• Features an open-drain interrupt output to notify the system of button presses or low-power events
• Provides high-voltage tolerance with ±36V swing and ±25kV ESD protection on the button input

Power Supply Controllers, Monitors Applications

• Battery-powered systems requiring extended run time via micropower operation
• Systems needing automatic turn-on functionality based on monitored supply voltage levels
• Applications requiring hardware-based power management with interrupt signaling capabilities

Power Supply Controllers, Monitors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific package markings against official datasheets. Check current availability as supply may be restricted. Ensure proper handling procedures are followed due to surface-mount packaging requirements.

Power Supply Controllers, Monitors Selection Notes

Select this variant when an active-low enable output is required for negative-enable polarity control. Consider the wide input voltage range and low quiescent current for battery applications. Evaluate the need for automatic turn-on features driven by the ON pin versus manual button control only. Compare against similar models like the LTC2955-1 if positive-enable logic is preferred.

Power Supply Controllers, Monitors Part Context

This component belongs to the LTC2955 series of micropower push-button controllers designed for efficient power management in portable and industrial electronics. It integrates monitoring, debouncing, and control logic into a compact DFN package, replacing discrete solutions for system power sequencing and shutdown management.
