TPS3805H33QDCKRQ1 Description

Short technical summary and product information.

The TPS3805H33QDCKRQ1 from Texas Instruments is a supervisory circuit designed for circuit initialization and timing supervision in processor-based systems. This dual-rail voltage detector monitors two supply voltages, with one fixed at 3.05V and the other adjustable.

 

Key electrical specifications include a typical supply current of 3µA at 3.3V, a reset threshold accuracy of ±1.5%, and a reset time delay of 0ms. The reset output is active-low and features a push-pull, totem pole driver.

 

This device is housed in a compact SC-70-5 package, suitable for surface mount applications. It operates reliably within an extended temperature range of -40°C to 125°C, making it suitable for demanding automotive and industrial environments. The TPS3805H33QDCKRQ1 is part of the TPS380x-Q1 family of voltage detectors qualified for automotive applications.

 

Designed for ease of use, the TPS3805H33QDCKRQ1 ensures proper system startup by asserting a reset signal when supply voltages fall below the configured thresholds. Its dual-rail monitoring capability and adjustable threshold provide flexibility in various power management designs.
