The TPS3808G15DRVR device uses a precision reference to achieve 0.5% threshold accuracy for VIT≤ 3.3 V. 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. The TPS3808G15DRVR device has a very low typical quiescent current of 2.4μA, so it is well-suited to battery-powered applications. It is available in the SOT-23 and 2-mm × 2-mm WSON packages, and is fully specified over a temperature range of –40°C to 125°C (TJ).
