The Texas Instruments TPS3839K50DBZR is a supply voltage supervisor designed for monitoring single voltage rails. It features an ultralow supply current of 150 nA (typical) and operates over a wide supply voltage range from 0.9 V to 6.5 V.
This device initiates an active-low reset signal when the VDD supply voltage drops below a factory-trimmed reset threshold. 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 TPS3839K50DBZR is available in a 3-pin SOT-23-3 package, suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C.
Key electrical specifications include a typical reset threshold voltage of 4.38V and a minimum reset timeout of 120ms. The output stage is push-pull with a totem pole configuration.
