TPL5110DDCR Nano-Power System Timer for Power Gating SOT23-6

Description

TPL5110DDCR Nano-Power System Timer for Power Gating SOT23-6

TPL5110DDCR – Key Specifications & Overview

The TPL5110DDCR is a nano-power system timer from Texas Instruments, ideal for ultra-low-power applications like power gating in battery-powered or duty-cycled systems. Here are its core specs:

Supply & Power

• Supply Voltage: Operates from 1.8 V to 5.5 V

• Typical Operating Current: 35 nA at 2.5 V

Timer Functionality

• Selectable Time Intervals: From 100 ms up to 7200 s (2 hours)

• Timer Accuracy: ±1% typical

• Selection Method: By adjusting resistor values (resistor-selectable interval)

• Manual Power-On: Supports manual MOSFET power-on and has a one-shot mode (timer fires once then stops)

Integrated Features

• Includes a MOSFET driver to gate power (acts as a power switch)

General Characteristics

• Package: 6-pin SOT-23-THIN (TSOT-23-6)

• Operating Temperature Range: −40 °C to +105 °C

• Intended Use Cases: Designed for battery-powered systems, IoT nodes, intruder or tamper detection, home automation sensors, thermostats, remote sensors, and more

Summary Table

What This Means In Practice

The TPL5110DDCR acts like an ultra-efficient timer-based switch:

• You set it to wake up your main system (like a microcontroller) at intervals ranging from a fraction of a second to two hours.

• When the timer fires, the built-in MOSFET driver activates power (turns on) to your system.

• Optionally, you can use “one-shot” mode to briefly power up only once.

• After the job is done (e.g., taking a measurement or transmitting data), your system can signal the TPL5110 to turn itself off again, consuming virtually no standby power (just 35 nA!).
