TLC7701IDR

Supervisors Overview

The TLC7701IDR is a single-channel voltage supervisory circuit manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It operates within a supply voltage range of 2 V to 6 V with a typical quiescent current of 9 µA. The device features a fixed threshold voltage of 1.1 V and an overvoltage threshold of 1.16 V. It provides programmable reset delay times and supports active high, active low, and push-pull output configurations. The component ensures system reliability through battery backup switching capabilities without requiring manual reset or watchdog functions.

Supervisors Feature Summary

• Provides single-input voltage supervision with configurable active high or active low outputs
• Features programmable reset delay timing for customized system response
• Includes battery backup switching functionality to maintain monitoring during power transitions

Supervisors Applications

• Monitoring microprocessor power rails for undervoltage conditions
• Supervising battery-powered systems with backup power switching
• Ensuring reliable startup sequences via programmable reset delays

Supervisors Procurement Notes

Verify the specific suffix 'IDR' corresponds to the SOIC-8 package and tape-and-reel delivery format. Confirm that the 1.1 V threshold aligns with the target supply rail requirements. Ensure the industrial temperature range specifications meet the operational environment constraints. Cross-reference the datasheet revision to confirm pinout compatibility with existing PCB layouts.

Supervisors Selection Notes

Select this component when a single-channel supervisor with low quiescent current is required. The 1.1 V threshold suits applications monitoring lower voltage rails. Consider the programmable delay feature if noise immunity or specific startup timing is critical. The SOIC-8 package offers a compact solution for space-constrained designs compared to larger packages.
