TPS3703A4330DSERQ1 Description

Short technical summary and product information.

The Texas Instruments TPS3703A4330DSERQ1 is a high-accuracy window supervisor IC designed for automotive applications. It monitors a single supply voltage and provides a reset output with a time delay when the voltage deviates from the specified window.

Key electrical specifications include an input voltage range of 1.7V to 5.5V, with an undervoltage lockout (UVLO) at 1.7V. The device features a typical threshold voltage of 3.3V, with multiple other fixed threshold levels available from 0.8V to 7.5V. Reset threshold accuracy is high, typically ±0.25% and ±0.7% over the operating temperature range of -40°C to 125°C. The quiescent current is very low at 7 µA maximum.

This supervisor IC offers features such as latching capability and manual reset. The reset output is active-low and open-drain. It operates over a wide temperature range of -40°C to 125°C. The device is qualified under AEC-Q100 for automotive applications.

The TPS3703A4330DSERQ1 comes in a 6-WSON package with dimensions of 1.5mm x 1.5mm, making it suitable for space-constrained designs. The surface mount type ensures easy integration into printed circuit boards.
