The Texas Instruments TPS3831K50DQNR is a single-channel voltage supervisory circuit designed for ultralow power applications. It monitors a single voltage supply and initiates an active-low reset signal when the VDD supply drops below a factory-trimmed threshold. The device features an ultralow supply current of 150 nA typical, making it ideal for battery-powered devices.
Key electrical specifications include an operating supply voltage range of 0.9 V to 6.5 V and a reset threshold accuracy of 1.6%. The reset output is active-low and push-pull, with a typical time delay of 200 ms after the VDD voltage rises above the threshold. The TPS3831K50DQNR also includes a manual reset input capability.
This supervisor IC is available in a compact 4-X2SON (1x1 mm) package, suitable for space-constrained designs. It operates within a temperature range of -40°C to 85°C. The device is designed to ignore fast transients on the VDD pin, ensuring reliable operation.
