DESCRIPTION

· The TPS3831 and TPS3839 devices are ultralow current (150 nA, typical) voltage supervisory circuits that monitor a single voltage.

· They initiate an active-low reset signal when the VDD supply voltage drops below the factory-trimmed reset threshold voltage.

· The reset output remains low for 200 ms (typical) after the VDD voltage rises above the threshold voltage and hysteresis.

· These devices are designed to ignore fast transients on the VDD pin.

· The TPS3831 includes a manual reset input that forces RESET low when MR is low.
