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.
