Product Overview
The TPS3839 is a Texas Instruments supply voltage monitor in the Power_Management category. It supervises VDD and drives a push-pull, active-low RESET output. Recommended operation covers 0.9 V to 6.5 V, while the output remains valid down to 0.6 V at IOL = 1 uA. Supply current is specified at 150 nA typical and 500 nA maximum with the output not connected across -40°C to 85°C and 0.9 V < VDD < 6.5 V.
The device supports power-up reset timing from 120 ms minimum to 350 ms maximum, with a 200 ms typical delay. VDD falling propagation delay is 20 us typical. RESET output low and high voltage limits are specified across multiple VDD and load-current ranges, supporting use in voltage-supervised reset circuits.
Package options include SOT-23-3 DBZ at 2.92 mm x 2.37 mm and X2SON-4 DQN at 1.00 mm x 1.00 mm. Variant thresholds include 0.9 V, 1.1 V, 1.52 V, 1.67 V, 2.325 V, 2.63 V, 2.93 V, 3.08 V, and 4.38 V typical negative-going threshold voltages.
