TPS3839G18DBZR Description

Short technical summary and product information.

The Texas Instruments TPS3839G18DBZR is a single-channel supply voltage supervisor designed for ultralow power applications. It monitors a single voltage supply and initiates an active-low reset signal when the VDD supply voltage drops below a factory-trimmed threshold.

Key electrical specifications include an operating supply voltage range of 0.9V to 6.5V and a typical ultralow supply current of 150 nA. The device features a push-pull RESET output and a reset timeout of 120ms minimum. It is designed to ignore fast transients on the VDD pin.

This supervisor operates within a temperature range of -40°C to 85°C. It is available in a compact SOT-23-3 package, suitable for surface mount applications.

The TPS3839G18DBZR is ideal for applications requiring reliable voltage monitoring and reset generation in power-sensitive systems.
