TLC7705QP

Supervisors Overview

The TLC7705QP is a single-channel voltage supervisory circuit manufactured by Texas Instruments, housed in an 8-pin PDIP package. It operates within a supply voltage range of 2 V to 6 V and features a fixed under-voltage threshold of 4.55 V with an over-voltage threshold of 4.63 V. The device provides programmable reset delay times and supports battery backup switching. It delivers active high, active low, or push-pull outputs with an accuracy of 5.4%. Designed for industrial environments, it functions reliably between -40°C and +125°C while consuming only 9 µA of quiescent current.

Supervisors Feature Summary

• Supports battery backup switching for seamless power transition monitoring
• Features programmable reset delay time for customized timing control
• Offers flexible output configurations including active high, active low, and push-pull modes

Supervisors Applications

• Industrial control systems requiring robust power supervision
• Portable equipment utilizing battery backup mechanisms
• Automotive electronics operating in extreme temperature ranges

Supervisors Procurement Notes

Verify the specific manufacturer source, as Rochester Electronics may distribute this component. Confirm that the PDIP-8 package matches your PCB footprint requirements. Ensure the fixed 4.55 V threshold aligns with your system's voltage specifications. Check RoHS compliance status if required by your manufacturing standards. Validate the operating temperature range against your environmental conditions.

Supervisors Selection Notes

Select this component when a fixed voltage threshold near 4.55 V is required without external resistor programming. The PDIP-8 package is suitable for through-hole mounting applications. Consider the 9 µA quiescent current for low-power designs. The wide operating temperature range makes it appropriate for harsh environments. Verify that the available output types meet your logic interface needs.

Supervisors Part Context

This part belongs to the TLC77xx series of voltage supervisors from Texas Instruments. These devices are designed to monitor power supply voltages and generate reset signals. The series typically includes variants with different thresholds and packages. This specific model focuses on single-channel monitoring with battery backup capabilities.

Supervisors Replacement Considerations

Check for TL7705BID or TLC7705QD as potential functional equivalents. Verify package compatibility between PDIP and SOIC/TSSOP options. Ensure threshold voltages match your design requirements. Confirm output drive capabilities are sufficient for your load.
