LTC2955CDDB-2#TRMPBF

Power Supply Controllers, Monitors Overview

The LTC2955CDDB-2#TRMPBF is a micropower pushbutton on/off controller with automatic turn-on functionality, manufactured by Analog Devices Inc. It manages system power by generating a clean enable output from the supply monitor input and the debounced pushbutton input. The device operates within an input voltage range of 1.6V to 36V and features a reset delay time of 200µs. It includes a threshold voltage of 800mV for monitoring purposes. The component is housed in an 8-lead DFN package (DFN-8) suitable for surface mount applications.

Power Supply Controllers, Monitors Feature Summary

• Integrates automatic turn-on capability to restore system power after an outage without manual intervention
• Provides debounced pushbutton input for reliable manual on/off control
• Generates a clean enable output signal to manage system power states

Power Supply Controllers, Monitors Applications

• System power management in portable electronics
• Battery-powered devices requiring automatic power restoration
• Embedded systems with pushbutton user interfaces

Power Supply Controllers, Monitors Procurement Notes

Verify availability status as distribution channels may indicate limited stock or special order requirements. Confirm the specific suffix #TRMPBF corresponds to the tape and reel packaging format required for your assembly process. Ensure compatibility with your PCB footprint for the 8-DFN package. Cross-reference the manufacturer datasheet for any recent product change notices affecting this part number.

Power Supply Controllers, Monitors Selection Notes

Select this component when automatic power restoration after a brownout or shutdown is required. The wide input voltage range supports various supply rails. The micropower consumption makes it suitable for battery-operated designs. Verify that the 800mV threshold and 200µs reset delay meet your system's timing specifications. Consider the DFN-8 package size constraints during layout.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC2955 family of micropower pushbutton controllers. It is functionally similar to the LTC2954 but adds automatic turn-on features. The CDDB-2 variant specifies the commercial temperature range and the specific pin configuration or internal settings defined by the -2 suffix. It is distinct from the hot-swap or protection variants also labeled under the LTC2955 series name.

Power Supply Controllers, Monitors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. The LTC2954 is a related controller but lacks the automatic turn-on feature. Verification against the official Analog Devices datasheet is required before considering any alternative components.
