Overview

The TMP102AQDRLRQ1 is an AEC-Q100 qualified digital temperature sensor designed for high-accuracy thermal monitoring in space-constrained automotive applications. It provides a 12-bit or 13-bit output over an I2C/SMBus interface and operates with a low supply voltage range of 1.4V to 3.6V. The device features an integrated SMBus Alert function and ultra-low power consumption, drawing as little as 1uA in shutdown mode.

Why Choose This Part

This sensor is AEC-Q100 Grade 1 qualified, ensuring reliability across a wide operating temperature range of -55C to 150C. Its SOT-563 package is significantly smaller than traditional SOT-23 sensors, and its ability to operate down to 1.4V makes it ideal for low-power battery-operated systems.

Applications

Automotive Infotainment Systems
Monitoring internal temperatures of head units and display controllers to manage thermal throttling.
Battery Management Systems (BMS)
Providing localized temperature sensing for battery cells and power electronics in EV/HEV environments.
Industrial Control Systems
Precise thermal monitoring of localized hotspots on dense PCBs where space is at a premium.

Getting Started

Interface the TMP102AQDRLRQ1 via its two-wire SMBus-compatible serial interface to any MCU. Use the One-shot mode to minimize power consumption by triggering a single temperature conversion and returning to shutdown. Configuration registers allow for setting high/low temperature limits for the hardware alert pin.
