±5V, ±12V (±15V) Dedicated
Microprocessor Voltage Monitors
_______________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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress rating s only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specificatio ns is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
