TPS37044BJOFDDFRQ1 TI Supervisory Circuit | TSOT-23-8 | 4.0V Threshold, Automotive

Product Overview

The TPS37044BJOFDDFRQ1 from Texas Instruments is a high-accuracy, automotive-grade supervisory circuit designed for monitoring power supply voltages in safety-critical applications. Housed in a compact TSOT-23-8 package, this device offers a fixed threshold voltage of 4.0V with a precision of ±1.5% over temperature. It features an open-drain RESET output with a built-in delay time of 200ms, ensuring reliable system reset during power-up, power-down, and brownout conditions. The device operates over a wide supply voltage range of 1.8V to 6.5V and consumes only 5µA of quiescent current, making it ideal for battery-powered and energy-efficient designs. With AEC-Q100 qualification, it is suitable for automotive and industrial applications requiring robust performance under harsh environments.
