The Texas Instruments TPS3839A09DBZR is an ultra-low power voltage supervisory circuit designed to monitor a single voltage supply. It operates with an ultralow supply current of 150 nA typical, making it suitable for power-sensitive applications.
The device initiates an active-low reset signal when the VDD supply voltage drops below the factory-trimmed reset threshold voltage of 0.9V. 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.
Key electrical specifications include an operating supply voltage range of 0.9V to 6.5V and a reset threshold accuracy of ±1.6% typical. The reset output is a push-pull type. The operating temperature range is -40°C to 85°C.
The TPS3839A09DBZR is available in a compact SOT-23-3 package, suitable for surface mount applications. It also comes in an X2SON package.
