TPS3820-50QDBVRQ1 Description

Short technical summary and product information.

The Texas Instruments TPS3820-50QDBVRQ1 is an active-low, push-pull automotive voltage supervisor with a watchdog timer and manual reset capability. It monitors a single supply voltage and provides a reset signal when the voltage drops below a threshold. The device features a typical threshold voltage of 4.55V and a reset timeout of 15ms minimum.

This supervisor IC includes a 0.2-second watchdog timer to ensure system reliability. It operates over an industrial temperature range of -40°C to 125°C and is housed in a compact SOT-23-5 package, suitable for surface mount applications. The device is qualified for automotive applications and meets AEC-Q100 standards.

With a low typical supply current of 0.015mA, the TPS3820-50QDBVRQ1 is designed for power-sensitive applications. Its active-low, push-pull output driver ensures a clear reset signal. The reset threshold accuracy is within 2.4% typical.
