TPS3831K33DQNR TI Supervisory Circuits | 4-X2SON(1x1) | 2.63V Threshold, Active Low

Product Overview

The TPS3831K33DQNR from Texas Instruments is a high-precision supervisory circuit designed for monitoring power supplies in digital systems. It provides a reset output during power-up, power-down, and brown-out conditions. The device operates with a supply voltage range of 0.7V to 6.0V and features a fixed threshold voltage of 2.63V. Housed in a compact 4-pin X2SON package (1mm x 1mm), it is ideal for space-constrained applications. The reset output is active low and remains asserted for a minimum of 120ms after VDD rises above the threshold, ensuring proper system initialization.
