Overview
The TPL5010DDCR is a programmable nano-power system 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 supply current. The device integrates a watchdog timer with manual reset functionality, featuring an open-drain output. It is housed in a compact SOT-23-THIN (TSOT-23-6) surface-mount package measuring 3.2 mm x 1.4 mm. The component supports an operating temperature range from -40°C to 85°C and complies with RoHS standards.
Feature Summary
- Ultra-low power consumption of 35 nA supply current
- Integrated watchdog timer with manual reset capability
- Wide supply voltage operation: 1.8 V to 5.5 V
- Compact SOT-23-THIN-6 package for space-constrained designs
Applications
- Battery-powered microprocessor systems requiring low standby current
- Microcontroller-based embedded systems needing watchdog protection
- Portable consumer electronics prioritizing energy efficiency
Procurement Notes
Verify the specific suffix 'DCR' indicates tape-and-reel packaging when sourcing. Confirm that the standard industrial temperature grade (-40°C to 85°C) meets the target application requirements. Check for AEC-Q100 qualified variants if automotive reliability is necessary. Ensure compatibility with the SOT-23-THIN footprint during PCB layout.
Selection Notes
Select this component for applications requiring minimal quiescent current alongside watchdog functionality. Compare against the TPL5110 series if RTC integration is needed instead of pure timing. Verify that the 1.8 V minimum supply voltage aligns with the system's battery discharge curve. Consider the TPL5010Q1 series for automotive environments requiring extended temperature ranges up to 125°C.
Part Context
The TPL5010DDCR belongs to the TPL5010D family of ultra-low-power timers. It serves as a non-volatile programmable timer solution designed to replace discrete transistor or capacitor-based watchdog circuits. The device simplifies design by integrating timing logic and reset control into a single small-footprint IC.
Replacement Considerations
The TPL5010DDCT is available in cut-tape packaging as an alternative to the reel format. For automotive applications, the TPL5010QDDCR or TPL5010QDDCTQ1 offers AEC-Q100 qualification and an extended temperature range up to 125°C.
