TPL5110QDDCTQ1

Overview

The TPL5110QDDCTQ1 is an AEC-Q100 qualified nano-power system timer designed for power gating applications. It features a built-in MOSFET driver to control external power rails, significantly reducing standby current in duty-cycled or battery-powered systems. The device operates within a supply voltage range of 1.8 V to 5.5 V and consumes only 35 nA of operating current. It is housed in a SOT-23-THIN-6 package and supports an extended industrial temperature range from -40°C to +125°C. This component is suitable for energy harvesting and wireless sensor networks where minimal power consumption is critical.

Feature Summary

• AEC-Q100 Grade 1 qualification for automotive reliability
• Ultra-low quiescent current of 35 nA
• Integrated MOSFET driver for power rail control
• SOT-23-THIN-6 surface-mount package

Applications

• Power gating in IoT sensor nodes
• Battery-operated wireless devices
• Energy harvesting systems
• Automotive monitoring circuits

Procurement Notes

Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification. Confirm the 'DDCT' suffix indicates the SOT-23-THIN-6 package and tape-and-reel shipping format. Ensure compatibility with the target voltage range of 1.8 V to 5.5 V for the specific application design.

Selection Notes

Select this part when automotive certification is required alongside ultra-low power consumption. Compare against the non-automotive TPL5110 if automotive grade is unnecessary. Ensure the integrated MOSFET driver specifications meet the load requirements of the power rail being controlled. Verify thermal performance within the -40°C to +125°C operating range.

Part Context

This component belongs to the TPL5110 family of nano-power system timers. The Q1 suffix distinguishes it as the automotive-grade variant compliant with AEC-Q100 standards, whereas the standard TPL5110 lacks this specific automotive qualification. Both share similar electrical characteristics but differ in reliability testing and documentation requirements.

Replacement Considerations

The standard TPL5110DDCRQ1 serves as a functional equivalent if automotive qualification is not strictly required. For designs needing watchdog functionality instead of simple power gating, consider the TPL5010 series. Verify pinout and package dimensions match before substitution.
