MAX8215_05 Datasheet, PDF (1/12 Pages) Maxim Integrated Products – ±5V, ±12V (±15V) Dedicated Microprocessor Voltage Monitors

19-0169; Rev 1; 11/05
±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.
