LTC1981ES5#TRPBF

Overview

The LTC1981ES5#TRPBF is a micropower high-side switch controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.7V to 36V and features an ultra-low quiescent current of 4µA. The device provides a fixed 100ms delay for soft-start or fault response, with a maximum on-resistance of 0.5Ω. It supports dual-channel control in the SOT-23 package.

Feature Summary

Ultra-low quiescent current consumption for battery efficiency
Integrated 100ms delay timer for controlled switching
Low on-resistance for minimal power loss
Wide input voltage compatibility

Applications

Battery-powered portable equipment
Hot-swap circuit protection
Power distribution management systems

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Ensure the component matches the required operating temperature range and package type for your design. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this controller when low standby current is critical for system longevity. Evaluate the 100ms delay requirement against system startup timing needs. Confirm that the 0.5Ω on-resistance meets the load current specifications without excessive thermal generation.

Part Context

This component belongs to the LTC1981 family of high-side switch controllers. It is designed for applications requiring efficient power management in space-constrained environments. The ES5 designation indicates the specific SOT-23-5 package variant used for surface-mount assembly.
