TPL5111DDCR

Overview

The TPL5111DDCR is a programmable timer and MOSFET driver integrated circuit manufactured by Texas Instruments. It operates within a supply voltage range of 1.8 V to 5.5 V and consumes a typical quiescent current of 35 nA. The device features an open-drain output capable of driving external N-channel MOSFETs, enabling ultra-low power system control. It is housed in a SOT-23-THIN (TSOT-23-6) surface-mount package and supports an operating temperature range from -40°C to +105°C. This component is designed for applications requiring precise timing intervals with minimal standby power consumption.

Feature Summary

• Ultra-low quiescent current of 35 nA
• Programmable timer with wide interval range
• Integrated MOSFET driver for external N-channel FETs
• SOT-23-THIN-6 package for compact designs

Applications

• Battery-powered sensor nodes
• Low-power IoT devices
• Periodic wake-up circuits
• Watchdog timers in microcontroller systems

Procurement Notes

Verify the specific suffix 'DDCR' corresponds to the tape-and-reel packaging configuration when sourcing. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering quantity aligns with standard reel sizes if high-volume production is intended. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Selection Notes

Select the TPL5111DDCR when system requirements demand sub-microampere standby currents combined with programmable timing intervals. Compare against the TPL5110 variant if different timing resolution or internal oscillator accuracy is required. Ensure the external MOSFET selected matches the driver's voltage and current capabilities. Verify that the SOT-23-THIN footprint fits within the available PCB area constraints.

Part Context

The TPL5111DDCR belongs to the TPL511x family of nano-power system timers from Texas Instruments. This series includes variants like the TPL5110 and TPL5111, which share similar low-power architectures but may differ in timing precision or internal oscillator characteristics. The 'DDCR' suffix specifically denotes the SOT-23-THIN-6 package and tape-and-reel delivery method, distinguishing it from cut-tape or tube-packaged alternatives.

Replacement Considerations

The TPL5110DDCR is a direct pin-compatible alternative within the same family. Verify if the specific timing accuracy or oscillator tolerance of the TPL5110 meets the application requirements before substitution. Other packages such as TPL5111DDCT offer identical functionality but in cut-tape format.
