Description

The TPS3808xxx 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 µ 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 ).
