The TPS3808G33QDBVRQ1 is a Supervisory Circuit with active-low open-drain output. The microprocessor supervisory circuit monitors system voltages from 0.4 to 5V, 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 voltage and /MR return above their thresholds. The TPS3808Gxx-Q1 device uses a precision reference to achieve 0.5% threshold accuracy for VIT<=3.3V. The reset delay time can be set to 20ms by disconnecting the CT pin, 300ms by connecting the CT pin to VDD using a resistor or can be user-adjusted from 1.25ms to 10s by connecting the CT pin to an external capacitor.
