LOW-QUIESCENT-CURRENT PROGRAMMABLE-DELAY SUPERVISORY CIRCUIT

The TPS3808 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 user-adjustable delay time after the SENSE voltage and MR return above their thresholds. The TPS3808 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 user adjusted between 1.25 ms and 10 s by connecting the CT pin to an external capacitor. The TPS3808 has a very low typical quiescent current of 2.4 μA, so it is well suited to battery-powered applications. It is available in a small SOT-23 package and is fully specified over a temperature range of –40°C to 125°C (TJ). By Texas Instruments
