Texas Instruments TPS3808G25DBVR Supervisor 1.7 V to 6.5 Supply 2.33 Threshold 0.3 s Delay Manual Active-Low SOT-23-6

The TPS3808G25DBVR is a Supervisory Circuit with active-low open-drain output and manual reset input. 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 manual reset (/MR) return above the respective thresholds. The TPS3808 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 between 1.25ms and 10s by connecting the CT pin to an external capacitor.
