TPS3103H20DBVR Description

Short technical summary and product information.

The Texas Instruments TPS3103H20DBVR is a supervisory circuit designed for processor-based systems, providing circuit initialization and timing supervision. It monitors a single supply voltage and asserts a reset signal when the voltage drops below a threshold.

 

Key electrical specifications include a 1.84V nominal voltage threshold and an active-low, open-drain reset output. The device offers a high trip-point accuracy of 0.75% and a typical supply current of just 1.2 μA. A power-on reset generator provides a delay time of 130 ms to ensure proper system reset.

 

This supervisor is suitable for applications using low-power DSPs, microcontrollers, or microprocessors, as well as portable and battery-powered equipment. It is available in a compact SOT-23-6 package, suitable for surface mount applications.

 

The TPS3103H20DBVR operates within a temperature range of -40°C to 85°C.
