TPS3813K33QDBVRQ1 Description

Short technical summary and product information.

The Texas Instruments TPS3813K33QDBVRQ1 is an automotive-grade voltage supervisor designed for processor monitoring applications. It provides a programmable window watchdog timer and features a reset time delay of 25 ms. The device monitors a single supply voltage, with typical threshold voltages including 2.93V and 4.55V, and offers reset threshold accuracy up to 2.4%.

 

This supervisor IC has an active-low, open-drain reset output and a low typical supply current of 9 µA. It is qualified for automotive applications under AEC-Q100, with a temperature grade of 1 (–40°C to +125°C ambient operating temperature). The TPS3813K33QDBVRQ1 is supplied in a compact 6-pin SOT-23-6 package, suitable for surface-mount designs.

 

Key features include undervoltage and overvoltage monitoring, a programmable watchdog timer, and a power-on reset generator. The device is also described as Functional Safety-Capable, indicating its suitability for safety-critical systems. Its precision supply-voltage monitoring supports multiple voltage levels including 2.5V, 3V, 3.3V, and 5V.
