TPL5010QDDCTQ1

Overview

The TPL5010QDDCTQ1 is an automotive-grade, ultra-low-power programmable timer and watchdog 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 operating current. The device features a single open-drain output and is housed in a compact SOT-23-THIN-6 package. Certified under the AEC-Q100 standard, it supports an extended industrial temperature range from -40°C to +125°C. This component is designed for applications requiring minimal power consumption while maintaining reliable system monitoring and timing functions.

Feature Summary

• Ultra-low power consumption with 35 nA operating current
• Automotive qualification compliant with AEC-Q100 standards
• Wide operating voltage range from 1.8 V to 5.5 V
• Extended temperature range supporting -40°C to +125°C

Applications

• Battery-powered IoT sensor nodes
• Automotive body control modules
• Portable medical devices
• Industrial monitoring systems

Procurement Notes

Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification. Confirm the 'DCT' suffix indicates the SOT-23-THIN-6 package and tape-and-reel shipping format. Ensure compatibility with the target voltage domain between 1.8 V and 5.5 V. Check for RoHS compliance status as indicated in official documentation. Validate that the open-drain output configuration meets the interface requirements of the host microcontroller.

Selection Notes

Select this part when AEC-Q100 certification is mandatory for the application environment. Choose the TPL5010QDDCTQ1 over non-automotive variants if operation above 85°C is required. Consider the SOT-23-THIN-6 footprint constraints during PCB layout. Verify that the 35 nA quiescent current aligns with strict battery life targets. Ensure the open-drain output can be properly pulled up to the desired logic level.

Part Context

This component belongs to the TPL5010 family of nano-powered timers. The Q1 designation specifically denotes automotive grade reliability. It serves as a watchdog or periodic wake-up timer for low-power embedded systems. The device integrates a programmable timeout mechanism to reset or alert the main processor.

Replacement Considerations

The TPL5010QDDCRQ1 is a reel-packaged alternative within the same automotive series. Non-automotive equivalents like the TPL5010DDCR lack AEC-Q100 certification and may have limited temperature ranges. Verify pinout and electrical specifications before substituting with other timer ICs.
