The Texas Instruments TPS3831G18DQNR is an ultralow power voltage supervisory circuit designed to monitor a single voltage supply. It features a typical supply current of just 150 nA, making it ideal for power-sensitive applications. The device initiates an active-low reset signal when the VDD supply voltage falls below the factory-trimmed reset threshold, which is available in multiple options including 1.67V.
The reset output remains low for a typical duration of 200 ms after the VDD voltage rises above the threshold and hysteresis. This supervisor is designed to ignore fast transients on the VDD pin. The TPS3831G18DQNR includes a manual reset input for added control. It operates over a temperature range of -40°C to 85°C and is available in a compact 4-X2SON (1x1 mm) package, suitable for surface mounting.
Key electrical characteristics include a reset threshold accuracy of 1.6% and a push-pull reset output. The device is designed for undervoltage monitoring only and ensures a valid reset for VDD greater than 0.6V.
