TPS3703A5180DSER TI Supervisory Circuits | 6-WSON (1.5X1.5) | 1.8V Threshold, Open-Drain Output

Product Overview

The TPS3703A5180DSER from Texas Instruments is a high-accuracy, low-power supervisory circuit designed for monitoring power supply voltages in a wide range of applications. It features a fixed threshold voltage of 1.8V with a precision of ±0.5% over temperature, ensuring reliable system reset during power-up, power-down, and brownout conditions. The device is offered in a compact 6-pin WSON package (1.5mm x 1.5mm), making it ideal for space-constrained designs. With an ultra-low quiescent current of 1.5µA (typical), it is well-suited for battery-powered and energy-efficient systems. The open-drain output (active low) can be connected to other open-drain outputs for wired-OR configurations.
