Applications/Uses

  • Data Acquisition Systems
  • Industrial Controllers
  • Industrial Equipment
  • Microprocessor Voltage Monitor: +5V, -5V, +12V, -12V Supply Monitoring (MAX8215), +5V, -5V, +15V, -15V Supply Monitoring (MAX8216)
  • Mobile Radios
  • Overvoltage/Undervoltage Detection with Uncommitted Comparator
  • Portable Instruments

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 temperature.
