TPS3703A4330DSER TI Supervisory Circuits | 6-WSON (1.5x1.5) | 4.33V Threshold, Active-High

Product Overview

The TPS3703A4330DSER 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 4.33V 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), this device is ideal for space-constrained designs. The TPS3703A4330DSER offers an active-high, open-drain RESET output, which remains asserted when the monitored voltage falls below the threshold and for a fixed delay after recovery. With ultra-low quiescent current of typically 5.5µA, it is suitable for battery-powered and energy-efficient systems.
