About This Product

■Summary

The MP640 family is a microprocessor (µP) supervisory circuit that can monitor system voltages from 0.4V and provide reset functionality. The RESET signal is asserted when the SENSE voltage falls below the threshold (VIT) or when the manual reset voltage (MR) is pulled to a logic low. The MP6400DG (J) -01's reset voltage can be adjusted with an external resistor divider, while the reset voltage can be factory set for standard voltage rails from 0.9V to 5V. When the SENSE voltage exceeds these thresholds, it is driven logic high after a user-programmable delay time. The MP6400's quiescent current is typically very low at 1.6uA, making it ideal for battery-powered applications. Provides a high precision reference to achieve ±1% threshold accuracy. The reset delay time is selected by a capacitor connected between CDELAY and GND, allowing the user to select any delay time from 2.1ms to 10s. Tying the CDELAY pin to VCC selects a 380ms delay time; leaving the CDELAY pin floating selects a 24ms delay time. The MP6400 is available in TSOT23 and 2 × 2mm 6-pin QFN packages.
