MAX8215

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 onchip. All comparators have open-drain outputs. These devices consume 250µA max supply current over temperature. ____________________________Features ♦ 4 Dedicated Comparators plus 1 Auxiliary Comparator ♦ 5V Dedicated Comparator Has ±1.25% Accuracy ♦ -5V, +12V, -12V, +15V, -15V Dedicated Comparators Have ±1.5% Accuracy ♦ Overvoltage/Undervoltage Detection or Programmable Delay Using Auxiliary Comparator ♦ Internal 1.24V Reference with ±1% Initial Accuracy ♦ Wide Supply Range: 2.7V to 11V ♦ Built-In Hysteresis ♦ 250µA Max Supply Current Over Temp. ♦ Independent Open-Drain Outputs ♦ All Precision Components Included MAX8215/MAX8216 ________________________Applications Microprocessor Voltage Monitor +5V, -5V, +12V, -12V Supply Monitoring (MAX8215) +5V, -5V, +15V, -15V Supply Monitoring (MAX8216) Overvoltage/Undervoltage Detection with Uncommitted Comparator Industrial Controllers Mobile Radios Portable Instruments Industrial Equipment Data-Acquisition Systems ______________Ordering Information PART MAX8215CPD MAX8215CSD MAX8215C/D MAX8215EPD MAX8215ES...
