Dual-
Voltage µP Supervisory Circuits with Sequenced Reset Outputs
General Description
The MAX6391/MAX6392 microprocessor (µP) supervisory circuits provide sequenced logic reset outputs for multicomponent or dual-
voltage systems.
Each device can monitor two supply
voltages and time-sequence two reset outputs to control the order in which system components are turned on and off.
The MAX6391/MAX6392 increase system reliability and reduce circuit complexity and cost compared to separate ICs or discrete components.
The MAX6391/MAX6392 monitor V CC as the master reset supply.
Both RESET1 and RESET2 are asserted whenever VCC drops below the selected facto...
