MAX8215：±5V、±12V (±15V)专用微处理器电压监测器
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 temperature.
