ISL6132

ISL6131, ISL6132 Multiple Voltage Supervisory ICs 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, and the ISL6132 is a two-voltage supervisor monitoring 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 Power-Good (PGOOD) signal that asserts high when the STATUS outputs are in their correct state. A stability delay of approximately 160ms ensures 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 OR’ing of the signals and interfacing to a wide range of logic levels. STATUS and PGOO...
