TPS3703A7330DSER TI Supervisory Circuits | 6-WSON (1.5X1.5) | 3.3V Threshold, Active-High

Product Overview

The TPS3703A7330DSER from Texas Instruments is a high-accuracy voltage supervisor designed for monitoring power supply voltages in a wide range of applications. It features a fixed threshold voltage of 3.3V with a precision of ±0.5% over temperature, ensuring reliable system reset and power-on reset generation. Housed in a compact 6-pin WSON package (1.5mm x 1.5mm), it is ideal for space-constrained designs. The device offers an active-high, open-drain RESET output with a built-in pull-up resistor, simplifying interface with microcontrollers and other logic devices. With ultra-low quiescent current of 5.5µA typical, it is suitable for battery-powered and energy-efficient systems.
