Low Quiescent Current, Programmable-Delay Supervisory Circuit

The TPS3808 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. The TPS3808 has a very low typical quiescent current of 2.4??A so it is well-suited to battery-powered applications. It is available in a small SOT23 and an ultra-small 2mm 2mm QFN PowerPAD?? package, and is fully specified over a temperature range of 40C to +125C (TJ). By Texas Instruments
