CAT8710
Quad Voltage Supervisor
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 −40°C to +85°C.
