Overview

The TMP235AEDBZRQ1 is an automotive-qualified, high-precision analog output temperature sensor designed for linear thermal monitoring over a wide -40C to 150C range. It provides a positive slope output of 10mV/degree C and is functional safety-capable, making it suitable for critical vehicle systems. The device operates on a low supply current of 9 microamps (typical at 25C), minimizing the impact of self-heating on measurement accuracy.

Why Choose This Part

The sensor features a high degree of linearity across the entire 190C temperature span, simplifying the transfer function for the host ADC. Its ultra-low current consumption of 9 microamps reduces power budget strain in always-on automotive systems. Being AEC-Q100 qualified and functional safety-capable, it offers the reliability needed for harsh environment deployments.

Applications

Automotive Powertrain
Monitoring thermal conditions in gasoline engines and electric power steering (EPS) modules.
Battery Management Systems (BMS)
Providing cell temperature feedback for safety and charging optimization in EV/HEV battery packs.
Infotainment and Head Units
Managing thermal throttling for automotive processors and display backlighting.
Industrial Functional Safety
Utilized in safety-critical loops where functional safety-capable components are required for system certification.

Getting Started

To evaluate this sensor, connect the VDD pin to a stable 2.3V to 5.5V supply and the VOUT pin to a high-impedance ADC input on a microcontroller. Ensure a 0.1 microfarad bypass capacitor is placed close to the VDD pin to minimize noise. For rapid prototyping, look for SOT-23 breakout boards or TI's generic analog sensor evaluation modules.
