Overview

  • ±1% Guaranteed Trip-Level Accuracy over Commercial Temp. Range
  • 4 Precision Comparators Plus Auxiliary Comparator
  • Built-in Hysteresis
  • Internal 1.25V Reference with 0.75% Initial Accuracy
  • ±1% Guaranteed Trip-Level Matching Between Channels over Commercial Temp. Range
  • Wide Supply Range: 2.75V to 11V
  • Controlled Comparator Response for Glitch Immunity
  • 33µA Max Supply Current Over Temp.

The MAX8213 and MAX8214 contain four precision voltage comparators capable of monitoring undervoltage and overvoltage conditions for both positive and negative supplies. Accurate trip-point setting is facilitated by the internal 1.25V reference. Not only is trip-level accuracy guaranteed to ±1% over the commercial temperature range, but the trip levels of all channels are guaranteed to match each other within ±1%. A fifth comparator channel monitors microprocessor voltages and generates delayed reset signals. The MAX8213 has open-drain outputs, while active pull-up outputs are incorporated in the MAX8214.
