Low Quiescent Current, Programmable-Delay Supervisory Circuit

DESCRIPTION The TPS3808 family of Microprocessor Supervisory Circuits monitor system voltages from 0.4V to 5.0V, 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 their thresholds. The TPS3808 uses a precision reference to achieve 0.5% threshold accuracy for V IT 3.3V. The reset delay time CAN be set to 20ms by disconnecting the C T pin, 300ms by connecting the C T pin to V DD using a resistor, or CAN be user-adjusted between 1.25ms and 10s by connecting the C T 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 40 C to +125 C (T J ). By Texas Instruments
