LTC2950CTS8-2#TRMPBF

Power Supply Controllers, Monitors Overview

The LTC2950CTS8-2#TRMPBF is a supervisory circuit manufactured by Analog Devices Inc., designed as a push-button on/off controller. It operates within a supply voltage range of 2.7V to 26.4V and draws a typical operating supply current of 6µA. The device utilizes an SOT-23-8 surface-mount package and features a reset delay time of 200µs. It monitors one input with a threshold voltage of 800mV, providing active high, active low, and open drain output types without manual reset or watchdog timer functionality.

Power Supply Controllers, Monitors Feature Summary

• Provides manual control of DC/DC converter shutdown pins via debounced push-button input
• Releases low leakage enable output to turn on the converter after button press
• Operates with ultra-low quiescent current for battery-powered applications

Power Supply Controllers, Monitors Applications

• Manual power control for DC/DC converters
• Battery-powered portable systems requiring low standby current
• Embedded systems needing simple hardware-based on/off switching

Power Supply Controllers, Monitors Procurement Notes

Verify availability status carefully as this specific part number may be subject to limited supply or factory special order constraints. Confirm the exact suffix matches the required package and temperature grade. Cross-reference the manufacturer datasheet for the latest lifecycle status and recommended replacement options if discontinuation is indicated.

Power Supply Controllers, Monitors Selection Notes

Select this component when a low-current, single-input supervisor is needed to manage power states via mechanical switches. Ensure the monitored voltage threshold aligns with the system's enable pin requirements. Consider the SOT-23-8 footprint constraints during PCB layout design.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC2950 family of push-button on/off controllers from Analog Devices. It shares core functionalities with variants like the LTC2954 and LTC2955 but differs in specific package options and monitoring thresholds. The family is designed to simplify system design by replacing complex logic circuits with a single IC solution.

Power Supply Controllers, Monitors Replacement Considerations

Check for direct substitutes within the LTC2950 series such as LTC2954ITS8-1#TRPBF or LTC2955CTS8-1#TRMPBF, ensuring pin compatibility and functional equivalence. Verify that any alternative maintains the same supply voltage range and output drive capabilities.
