TPS3890/TPS3890-Q1 Precision Voltage Supervisors

Texas Instruments TPS3890/TPS3890-Q1 Precision Voltage Supervisors come with a low-quiescent current that monitors system voltages as low as 1.15V. The device asserts 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 voltage and manual reset (MR) return above the respective thresholds. The TPS3890/TPS3890-Q1 family uses a precision reference to achieve 1% threshold accuracy. The reset delay time can be user-adjusted between 40µs and 30s by connecting the CT pin to an external capacitor. The TPS3890/TPS3890-Q1 has a very low quiescent current of 2.1µA and is available in a small 1.5mm×1.5mm package, making the device well-suited for battery-powered and space-constrained applications. The device is fully specified over a temperature range of –40°C to +125°C (TJ). The Texas Instruments TPS3890-Q1 devices are AEC-Q100 qualified for automotive applications.
