_______________General Description
The MAX8215 contains five
voltage comparators; four are for monitoring +5V, -5V, +12V, and -12V, and the fifth monitors any desired
voltage. The MAX8216 is identical, except it monitors ±15V supplies instead of ±12V. The resistors required to monitor these
voltages and provide comparator hysteresis are included onchip. All comparators have open-drain outputs. These devices consume 250µA max supply current over temperature.
