The ISL6131 and ISL6132 are a family of high accuracy multi voltage supervisory ICs designed to monitor voltages greater than 0.7V in applications ranging from microprocessors to industrial power systems. The ISL6131 is an undervoltage four supply supervisor whereas the ISL6132 is a two voltage supervisor monitoring both for undervoltage (UV) and overvoltage (OV) conditions.
Both ICs feature four external resistor programmable voltage monitoring (VMON) inputs each with a related STATUS output that individually reports the related monitor input condition. In addition there is a PGOOD (power good) signal that asserts high when the STATUS outputs are in their correct state. There is a stability delay of approximately 160ms to ensure that the monitored supply is stable before STATUS and PGOOD are released to go high. The PGOOD and STATUS outputs are open-drain to allow ORing of the signals and interfacing to a wide range of logic levels.
STATUS and PGOOD outputs are guaranteed to be valid with IC bias lower than 1V eliminating concern about STATUS and PGOOD outputs during IC bias up and down. VMON inputs are designed to ignore momentary transients on the monitored supplies.
