_______________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 on-

chip. All comparators have open-drain outputs. These

devices consume 250µA max supply current over tem-

perature.
