TPS3803-01QDCKRQ1 Description

Short technical summary and product information.

The Texas Instruments TPS3803-01QDCKRQ1 is a supervisory circuit designed for circuit initialization and timing supervision, primarily for DSPs and processor-based systems. This device monitors a single voltage supply and asserts a reset signal when the voltage drops below a defined threshold. It features an adjustable threshold voltage, configurable via external resistors, and an active-low, open-drain reset output.

 

Key electrical specifications include a typical threshold voltage of 1.226V or 1.4V, with a reset threshold accuracy of 1.5%. The typical supply current is a low 3 µA at 3.3V. The reset timeout is typically 5 µs. The operating temperature range is -40°C to 125°C.

 

This supervisor IC is housed in a compact 5-pin SC-70-5 package, suitable for surface mount applications. Its design makes it ideal for applications requiring reliable power-on reset and voltage monitoring functions, ensuring proper system initialization and operation.

 

The TPS3803-01QDCKRQ1 is qualified for automotive applications, indicating its suitability for demanding environments.
