Overview

The UMWTMP36GT9Z is a low-voltage analog temperature sensor that provides a linear voltage output directly proportional to the Celsius temperature. It operates on a single supply between 2.7V and 5.5V and does not require any external calibration to provide typical accuracies of +/-2degC at 25degC. With a very low typical operating current of 50uA and a dedicated shutdown mode, it is well-suited for power-sensitive applications.

Why Choose This Part

The device offers a high-scale factor of 10 mV/degC and a 750mV output at 25degC, making it easy to interface with standard microcontroller ADCs. Its extremely low 0.5uA shutdown current minimizes drain when measurements are not required. The TO-92 package provides a familiar, easy-to-mount form factor for through-hole PCB designs or remote sensing applications.

Applications

Battery Management Systems
Monitoring cell temperatures in portable electronics where low current consumption is critical.
Environmental Control
Providing feedback for HVAC systems and thermostat controls within a -40degC to 125degC range.
Thermal Compensation
Adjusting the bias of sensitive analog circuitry to compensate for temperature-induced drift.
Industrial Process Monitoring
Reliable temperature sensing in industrial equipment using the robust TO-92 through-hole package.

Getting Started

To use this sensor, connect the VDD pin to a 2.7V-5.5V supply and the GND pin to system ground, then read the VOUT pin using a microcontroller ADC. Convert the measured voltage to temperature using the formula: Temp (degC) = (Vout in mV - 500) / 10. Ensure a 0.1uF ceramic bypass capacitor is placed close to the VDD pin to minimize noise in the analog output.
