Description

The TPS3890-Q1 is a precision voltage supervisor with low-quiescent current that monitors system voltages as low as 1.15 V, asserting an open-drain RESET signal when the SENSE voltage drops below a preset threshold or when the manual reset(MR) pin drops to a logic low. The RESET output remains low for the user-adjustable delay time after the SENSE yoltage and manual reset (MR) return above the respective thresholds. The TPS3890-Q1 family uses a precision reference to achieve 1% threshold accuracy, The reset delay time can be user-adjusted between 25 us and 30 s by connecting the CT pin to an external capacitor. The TPS3890-Q1 has a very low quiescent current of 2.1 μA and is available in a small 1.5-mm× 1.5-mm package, making the device well-suited for battery-powered and space-constrained applications. The device is fully specified over a temperature range of -40℃ to+125°C (T).
