TPL5010DDCT

Overview

The TPL5010DDCT is an ultra-low-power programmable timer integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 1.8 V to 5 V and consumes only 35 nA of supply current. The device features a single internal timer with an open-drain output type, housed in a compact SOT-23-THIN-6 (TSOT-23-6) surface-mount package. Designed for minimal power consumption, it supports operating temperatures from -40°C to +105°C. This component functions as a nano power system timer suitable for applications requiring precise timing control with negligible standby power draw.

Feature Summary

• Ultra-low power consumption of 35 nA supply current
• Programmable timer functionality with open-drain output
• Wide supply voltage range: 1.8 V to 5 V
• Compact SOT-23-THIN-6 surface-mount package

Applications

• Battery-powered sensor nodes requiring long sleep intervals
• Watchdog timer implementations in low-power microcontroller systems
• Periodic wake-up circuits for energy harvesting devices
• Manual reset triggers in portable electronic equipment

Procurement Notes

Verify the specific suffix 'DDCT' corresponds to the cut-tape or reel packaging variant required for assembly. Confirm that the standard 16-week production cycle aligns with project timelines. Ensure compatibility with the target PCB footprint for the SOT-23-THIN-6 package. Check for any recent PCN updates regarding assembly sites or marking changes before finalizing procurement orders.

Selection Notes

Select the TPL5010DDCT when design constraints demand sub-microampere standby currents and programmable delay intervals. Compare against the TPL5110 series if manual reset functionality is explicitly required, as the TPL5010 focuses on basic timer operations. Ensure the load connected to the open-drain output matches the voltage levels within the 1.8 V to 5 V operating range. Validate thermal performance within the -40°C to +105°C industrial temperature range.

Part Context

The TPL5010DDCT belongs to the TPL5010 family of ultra-low-power timers from Texas Instruments. It shares core specifications with the TPL5010DDCR but differs in packaging format. Related components include the TPL5110 series, which adds manual reset capabilities, and the automotive-grade TPL5010QDDCTQ1, which offers extended temperature ranges and AEC-Q100 qualification. The TPL5010EVM serves as the official evaluation board for this family.

Replacement Considerations

The TPL5010DDCR is a direct functional substitute differing primarily in packaging configuration. For designs requiring manual reset input, the TPL5110 series provides pin-compatible alternatives with enhanced control features. Automotive applications should consider the TPL5010QDDCTQ1 for qualified reliability standards.
