Features, Applications

The TPS3808 family of microprocessor supervisory circuits monitors system voltages from 5 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 useradjustable delay time after the SENSE voltage and manual reset (MR) return above the respective thresholds. The TPS3808 device uses a precision reference to achieve 0.5% threshold accuracy for VIT 3.3 V. The reset delay time can be set ms by disconnecting the CT pin, ms by connecting the CT pin to VDD using a resistor, or can be useradjusted between 1.25 ms and s by connecting the CT pin to an external capacitor. The TPS3808 device has a very low typical quiescent current it is well-suited to battery-powered applications. It is available in the SOT-23 and 2-mm WSON packages, and is fully specified over a temperature range to 125C (TJ). Device Information(1)
