The MAX6736MAX6745 monitor I/O supply voltages (V CC1) from 1.8V to 5.0V and core supply voltages (VCC2) from 0.9V to 3.3V with factory-trimmed reset threshold voltage options (Table 1). An external adjustable RSTIN input option allows monitoring voltages down to 0.5V. A variety of push-pull or open-drain reset outputs along with manual reset input and power-fail input/output features are available (see the S elector Guide ). The MAX6736MAX6745 are offered in a space-saving 5-pin SC70 package and operate over the -40C to +85C temperature range.
