LTC2955ITS8-2#TRMPBF

Power Supply Controllers, Monitors Overview

The LTC2955ITS8-2#TRMPBF is a pushbutton on/off controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 1.5V to 36V and features a maximum input voltage rating of ±36V. The device draws a typical supply current of 1.2 µA, ensuring low power consumption during operation. It is housed in a TSOT-23-8 surface-mount package and is designed for industrial applications with an operating temperature range spanning from -40°C to +85°C.

Power Supply Controllers, Monitors Feature Summary

• Enables system power control via external pushbutton interface
• Provides automatic turn-on functionality for battery backup systems
• Integrates power fail detection capabilities

Power Supply Controllers, Monitors Applications

• Portable instrumentation power management
• Industrial automation equipment shutdown sequences
• Battery-powered devices requiring auto wake-up

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging when ordering. Confirm that the -2 variant matches the required threshold or timing specifications compared to other family members like the -1 variant. Ensure compatibility with the target PCB footprint for the TSOT-23-8 package. Cross-reference the manufacturer datasheet for any recent product change notifications affecting pinout or electrical characteristics.

Power Supply Controllers, Monitors Selection Notes

Select this component when a compact solution for manual power switching is required alongside automatic power restoration features. The low quiescent current makes it suitable for energy-constrained portable designs. Compare against the LTC2950 series if auto-turn-on is not needed, as the LTC2955 specifically includes this capability. Ensure the input voltage range covers the system's operational and transient conditions.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC2955 supervisory circuit family from Analog Devices. It is distinct from the LTC2950, which lacks the auto-turn-on feature. The device serves as a specialized PMIC component for managing power states in embedded systems. It complements other monitoring ICs by handling user interaction logic rather than just voltage supervision.

Power Supply Controllers, Monitors Replacement Considerations

The LTC2955ITS8-1#TRMPBF is a related variant within the same package but may differ in auto-turn-on configuration. Verify functional equivalence before substitution.
