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 on-chip. All comparators have open-drain outputs. These devices consume 250μA max supply current over temperature. 4 Dedicated Comparators plus 1 Auxiliary Comparator
