TPS3808G01QDRVRQ1

Description
The TPS3808Gxx-Q1 microprocessor supervisory circuits monitor system voltages from 0.4 V to 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 MR return above their thresholds.
The TPS3808Gxx-Q1 device uses a precision reference to achieve 0.5% threshold accuracy for VIT ≤ 3.3 V.
The reset delay time can be set to 20 ms by disconnecting the CT pin, 300 ms by connecting the CT pin to VDD using a resistor, or can be useradjusted from 1.25 ms to 10 s by connecting the CT pin to an external capacitor.
The TPS3808Gxx-Q1 has a very low typical quiescent current of 2.4 μA, so it is well suited for battery-powered applications.
The device is available in a small SOT-23 package (one option available in WSON) and is fully specified over a temperature range of –40°C to +125°C (TJ).
