... The MAX6709 consumes only 35µA (typ) of supply cur- rent. The MAX6714 consumes only 60µA (typ) of supply current. The MAX6709/MAX6714 operate with supply voltages of 2.0V to 5.5V. An internal undervoltage lock- out circuit forces all four digital outputs low when V drops below the minimum operating voltage ...

... Power-Supply Input. Connect V forces all PWRGD_ outputs low when not a monitored voltage for the MAX6709. For the MAX6714, RESET asserts low when V drops below its threshold. Manual Reset Input. Force MR low to assert the RESET output. RESET remains asserted for MR — 1 the reset timeout period after MR goes high ...

... Figure 2. MAX6714 Functional Diagram as an adjustable voltage monitor, general-purpose comparator, or digital-level translator. The MAX6714 quad voltage monitor/reset offers one fixed input with internal timing for µP reset, three power- fail comparators, and a manual reset input (MR). RESET drops below its threshold ...

... The open-drain outputs of the MAX6709/MAX6714 can be configured to detect an undervoltage condition. Figure 3 shows a configuration where an LED turns on when the comparator output is low, indicating an undervoltage condition. The MAX6709/MAX6714 can also be used in applica- tions such as system supervisory monitoring, multivolt- age level detection, and V bar graph monitoring CC (Figure 4) ...

... MR to GND provides additional noise immunity. Reseting the µP from a 2nd Voltage The MAX6714 can be configured to assert a reset from a second voltage by connecting the power-fail output to manual reset. As the V goes low and asserts the reset output for the reset time- out period after the manual reset input is deasserted ...
