MAX8214ACPE+

MAXIM INTEGRATED PRODUCTS  MAX8214ACPE+  芯片, 微处理器监控器, 11V, DIP-16

The is a complete microprocessor µP voltage monitor in 16 pin DIP package. It contains four precision voltage comparators capable of monitoring under voltage and overvoltage conditions for both positive and negative supplies. An accurate trip point setting is facilitated by the internal 1.25V reference, trip level accuracy is not only provided to ±1% over the commercial temperature range but also trip levels of all channels are set to match each other within ±1%. A fifth comparator channel monitors microprocessor voltages and generates delayed reset signals. It is suitable for driving LEDs or for circuits where outputs need to be wire-ORed.
