Key Features
- Ultra-low quiescent current of 35nA enables battery-powered designs to last years without recharging
- Adjustable timer interval from 100ms to 7200s set by a single external resistor
- Wide supply voltage range of 1.8V to 5.5V supports diverse power rail configurations
- Hardware-based timer eliminates the need for a microcontroller in periodic wake-up applications
- Active-low DONE pin allows direct control of load switches or enable pins
Applications
The TPL5110DDCR is ideal for IoT sensor nodes and wireless devices that require periodic wake-up cycles while spending most of their time in deep sleep, dramatically extending battery life. It is widely used in wearable electronics, environmental monitoring systems, and smart metering devices where a microcontroller would otherwise remain powered just to count time. Its tiny SOT-23 package and single-resistor configuration make it a drop-in solution for ultra-low-power interval timing in portable and energy-harvesting applications.

Frequently Asked Questions
What is the supply voltage range and quiescent current of the TPL5110DDCR?
The TPL5110DDCR operates from a supply voltage of 1.8V to 5.5V and draws an ultra-low quiescent current of only 35nA, making it suitable for battery-powered systems that must operate for years on a small coin cell or harvested energy source.
How do I set the timer interval on the TPL5110DDCR?
The timer interval is set by connecting a single external resistor between the REXT pin and GND. The resistance value determines the period, which is adjustable from 100ms up to 7200 seconds (2 hours). Texas Instruments provides a resistance-to-interval lookup table in the datasheet to simplify component selection.
What are the typical applications for the TPL5110DDCR?
The TPL5110DDCR is commonly used in IoT sensor nodes, wearable devices, smart meters, and environmental monitors where a low-power periodic wake-up timer is needed. It replaces a always-on microcontroller by driving an external load switch or enabling a processor only when a measurement or transmission is required, minimising system power consumption.
What package does the TPL5110DDCR come in and what is its footprint?
The TPL5110DDCR is housed in a 6-pin SOT-23 (TSOP-6) thin small-outline package with a body size of approximately 1.6mm × 2.9mm. This compact footprint makes it easy to integrate into space-constrained PCB designs alongside sensors, load switches, or microcontrollers.
Is the TPL5110DDCR RoHS compliant and lead-free?
Yes, the TPL5110DDCR is fully RoHS compliant and lead-free (Pb-free code: Yes, JESD-609 code: e4). It is manufactured using a plastic/epoxy package body and meets international environmental regulations for use in consumer, industrial, and medical electronics.
