The CAT8710 is a space-saving, precision quad voltage supervisor, designed to monitor up to four supply voltages with a single device. When any supply voltage drops below its preset threshold, the CAT8710 will output a single reset to the threshold. One CAT8710 IC eliminates the need for multiple reset circuits, which minimizes system components and improves reliability. The CAT8710 provides 2 factory preset thresholds for monitoring 3.3 V, 3.0 V, 2.5 V, and 1.8 V supplies within 5% and 2 user-selectable thresholds, adjustable down to 0.62 V with 2% accuracy. On power up, the reset remains low for 120 ms typical, after all voltages have risen above their selected thresholds. The output remains valid as long as VDD remains above 1 V. The CAT8710 is available in a 6-pin SOT23 package and operates over the industrial temperature range of -40C to +85C.
