TPS3831L30DQNR Description

Short technical summary and product information.

The Texas Instruments TPS3831L30DQNR is an ultralow power, single-channel voltage supervisory circuit. It monitors a single voltage supply and initiates an active-low reset signal when the VDD supply voltage drops below a factory-trimmed reset threshold voltage, specifically 2.63V for this part.

This device features an operating supply voltage range of 0.9V to 6.5V and consumes a typical supply current of only 150 nA, making it ideal for low-power applications. The reset output remains low for a typical duration of 200 ms after the VDD voltage rises above the threshold and hysteresis. It is designed to ignore fast transients on the VDD pin.

The TPS3831L30DQNR includes a manual reset input and provides a push-pull reset output. It has a reset threshold accuracy of 1.6% and a reset timeout of 120 ms minimum. The operating temperature range is -40°C to 85°C.

This supervisor is available in a compact 4-X2SON (1x1 mm) package, suitable for surface mount applications. The package type is also described as 4-XDFN Exposed Pad.
