... VxIN falls below Vrst. The device is designed with typical hysteresis of 0.3% with respect to its threshold to help prevent oscillation due to noise and is immune to brief power-supply transients. V2IN The V2IN is used to power the STM6710 device. In normal operations V2IN is also monitored. For STM6710Q and STM6700 variations this pin is the V not monitored. Ground (V ...

... The STM6710 is capable of monitoring voltages in a multi-supply application. The device is available in several pre-set voltage thresholds for power supplies of 1.8 V, 2.5 V, 3.0 V, 3.3 V and 5.0 V. The STM6710 is powered by the V2IN pin which is also a monitored voltage, thus making this a quad voltage monitor. The STM6710Q and STM6700 use this ...

... Adding manual reset capability Figure 8 shows a circuit which can be used to add manual reset capability for the STM6710. Depressing the push button switch short circuits the analog input to ground and initiates a RESET pulse. The switch must be open for at least 140 ms in order to de-assert the RESET output ...
