LTC2953CDD-2#PBF

Power Supply Controllers, Monitors Overview

The LTC2953CDD-2#PBF is a push-button on/off controller with integrated voltage monitoring, manufactured by Analog Devices Inc. It manages system power via a push-button interface, featuring an enable output to toggle system power and an interrupt output for button status. The device operates within a supply voltage range of 2.7V to 27V and draws a typical supply current of 14 µA. It is housed in a 12-WFDFN exposed pad package and functions within an operating temperature range of 0°C to 70°C.

Power Supply Controllers, Monitors Feature Summary

• Manages system power through a dedicated push-button interface
• Integrates voltage monitoring capabilities for supply supervision
• Provides an enable output to control system power states
• Delivers an interrupt output indicating denunciated push-button status

Power Supply Controllers, Monitors Applications

• Battery-powered systems requiring low standby current
• Portable electronics needing efficient power management
• Industrial equipment utilizing push-button controls

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when ordering. Confirm the 12-WFDFN package dimensions match your PCB footprint requirements. Ensure the 2.7V to 27V input range aligns with your system's supply voltage. Check for any lead-free or RoHS compliance documentation if required by your manufacturing standards.

Power Supply Controllers, Monitors Selection Notes

Select this component when a low-power push-button interface is required alongside voltage supervision. Compare the 14 µA supply current against other controllers if battery life is critical. Consider the 12-WFDFN package size relative to available board space. Verify that the open-drain interrupt output compatibility matches your microcontroller inputs.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC2953 series of push-button on/off controllers from Analog Devices. It shares functional similarities with the LTC2953CDD-1#TRPBF but differs in packaging and potentially threshold settings. The series is designed for managing power in portable and industrial applications where user interaction via buttons is necessary.

Power Supply Controllers, Monitors Replacement Considerations

The LTC2953CDD-1#TRPBF is a related variant in the same family, offering similar functionality but in a tape-and-reel package. Verify pin-to-pin compatibility and electrical specifications before substitution. No other direct public substitutes are confirmed in the provided data.
