... General Description The MIC2772 is a dual power supply supervisor that provides under-voltage monitoring and power-on reset generation. It may replace two discrete voltage supervisors such as MIC1810, MIC1815, MIC809, MIC811, MIC6315, etc. The two voltage supervisors are completely independent. Each functional block features an under-voltage detector, a delay-generator, and a de-bounced manual reset input ...

... MOSFET structure. A pull-up resistor must be used to pull this output to some voltage. For most applications, this voltage will be the same power supply that supplies VCC to MIC2772 possible however to tie this resistor to some other voltage. This will allow the MIC2772 to monitor one voltage while level-shifting the /RESET output to some other voltage ...
