TPS37043A4OFDDFRQ1 TI Supervisory Circuits | TSOT-23-8 | 2.7V-5.5V, 4.4V Threshold

Product Overview

The TPS37043A4OFDDFRQ1 from Texas Instruments is a high-accuracy, dual-channel voltage supervisor designed for monitoring multiple supply rails in automotive and industrial applications. Housed in a compact TSOT-23-8 package, it offers precise undervoltage and overvoltage detection with a fixed threshold of 4.4V. Operating over a wide supply range of 2.7V to 5.5V, it ensures reliable system reset and protection. The device features open-drain outputs with internal pull-up resistors, enabling easy integration with microcontrollers and other logic circuits. With a typical quiescent current of only 5.5µA, it is ideal for power-sensitive designs.
