MC34064

THE INFINITE POWER OF INNOVATION MC33064 / MC34064 UNDERVOLTAGE SENSING CIRCUIT PRODUCTION DATA SHEET DESCRIPTION The MC34064 is an undervoltage sensing collector output stage capable of sinking circuit designed specifically for use as a up to 60mA. The MC34064's RESET reset controller in microprocessor- based output is specified to be fully functional at systems. It offers the designer an VIN=1V. A major improvement over economical, space-efficient solution for low competing products is the glitch-free supply voltage detection when used in supply current during undervoltage combination with a single pullup resistor. detection. Competing products demand a Adding one capacitor offers the step function increase in operating current functionality of a programmable delay time during the time that you least want or need after power returns. The 34064 consists of a it: during power loss.
