TPS3839E16DBZR Description

Short technical summary and product information.

The Texas Instruments TPS3839E16DBZR is a single-voltage supervisory circuit designed for ultralow power applications. It operates over a supply voltage range of 0.9 V to 6.5 V and consumes a typical quiescent current of just 150 nA.

This device initiates an active-low reset signal when the VDD supply voltage drops below a factory-trimmed reset threshold, which is 1.52V typical for this specific part. The reset output remains active for a minimum of 120 ms after the VDD supply rises above the threshold and hysteresis. It is designed to ignore fast transients on the VDD pin, ensuring reliable operation.

The TPS3839E16DBZR features a push-pull reset output and a reset threshold accuracy of ±1.6%. It is available in a compact SOT-23-3 package, suitable for surface mount applications. The operating temperature range is -40°C to 85°C.

This supervisor is ideal for applications requiring precise voltage monitoring and a reliable reset signal with minimal power consumption, such as battery-powered devices and portable electronics.
