TPL5010QDDCRQ1

Overview

The TPL5010QDDCRQ1 is an automotive-grade, nano-powered system supervisor timer manufactured by Texas Instruments. It operates within a supply voltage range of 1.8 V to 5.5 V and consumes only 35 nA of quiescent current. The device features a single open-drain output and is housed in a SOT-23-THIN-6 package. Certified under AEC-Q100 standards, it supports operating temperatures from -40°C to +125°C. This component functions as a watchdog timer with programmable timeout intervals, designed for low-power applications requiring reliable system monitoring without shutdown capabilities.

Feature Summary

• Ultra-low power consumption of 35 nA
• AEC-Q100 qualified for automotive reliability
• Wide supply voltage range: 1.8 V to 5.5 V
• Open-drain output configuration

Applications

• Automotive microcontroller supervision
• Low-power embedded system monitoring
• Battery-operated automotive electronics

Procurement Notes

Verify the specific suffix 'RQ1' corresponds to the reel packaging variant when sourcing. Confirm AEC-Q100 qualification status through official Texas Instruments documentation. Ensure compatibility with SOT-23-THIN-6 footprint requirements during procurement planning.

Selection Notes

Select this component for applications requiring minimal standby current and automotive certification. The 1.8 V minimum supply voltage suits battery-backed systems. Verify that the open-drain output interface aligns with the target microcontroller's input requirements.

Part Context

This part belongs to the TPL5010 series of system supervisors. It shares core specifications with the TPL5010QDDCTQ1, differing primarily in packaging quantity rather than electrical function. Both variants serve identical roles in automotive timing and supervision circuits.

Replacement Considerations

TPL5010QDDCTQ1 serves as a functional equivalent with identical electrical characteristics, differing only in factory packaging quantity (cut tape vs. reel).
