鹵5V, 鹵12V (鹵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 鹵15V supplies instead of
鹵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 250碌A(chǔ) max supply current over tem-
perature.
