MAX8215/MAX8216 19-0169 Rev 1 11/05 5V, 12V (15V) Dedicated Microprocessor Voltage Monitors General Description Features 4 Dedicated Comparators plus 1 Auxiliary The MAX8215 contains five voltage comparators four Comparator are for monitoring +5V, -5V, +12V, and -12V, and the fifth monitors any desired voltage. The MAX8216 is 5V Dedicated Comparator Has 1.25% Accuracy identical, except it monitors 15V supplies instead of -5V, +12V, -12V, +15V, -15V Dedicated 12V. The resistors required to monitor these voltages Comparators Have 1.5% Accuracy and provide comparator hysteresis are included on- Overvoltage/Undervoltage Detection or chip. All comparators have open-drain outputs. These Programmable Delay Using Auxiliary Comparator devices consume 250A max supply current over tem- Internal 1.24V Reference with 1% Initial Accuracy perature.
