Microprocessor supervisory IC
18 April 2018, Analogue, Mixed Signal, LSI

The PT7M3808 family of microprocessor supervisory circuits from Diodes Incorporated monitor system voltages from 0,4 V to 5,0 V, and feature threshold accuracy from 0,5% and an adjustable delay time from 1,25 ms to 10 ms. Offered in fixed-threshold versions for standard voltage rails between 0,9 V and 5,0 V, and with an adjustable threshold version down to 0,4 V, the PT7M3808 uses a precision reference to provide a 0,5% negative-going input threshold accuracy when monitoring voltages up to 3,3 V and 1% accuracy at voltages from 3,3 V to 5,0 V. The delay time is adjusted from 1,25 ms to 10 ms by connecting an external capacitor to the CT pin; a longer 20 ms or 300 ms delay is possible by connecting a resistor in one of two configurations.
