The MAX8215 contains five voltage comparators; fourare for monitoring +5V, -5V, +12V, and -12V, and thefifth monitors any desired voltage. The MAX8216 isidenTIcal, except it monitors ±15V supplies instead of±12V. The resistors required to monitor these voltagesand provide comparator hysteresis are included on-chip. All comparators have open-drain outputs. Thesedevices consume 250µA max supply current over tem-perature.
