The MC34164D-5R2 is an undervoltage sensing circuit designed for use as a reset controller in portable microprocessor-based systems, emphasizing extended battery life. It operates with a single external resistor and features a bandgap reference, precise comparator thresholds, and built-in hysteresis to prevent erratic reset behavior. The device can sink over 6.0 mA at the reset output and guarantees operation down to 1.0 V input with very low standby current, as low as 9.0 µA. This supervisor is suitable for monitoring 3.0 V or 5.0 V power supplies in various applications, including automotive, consumer, and industrial equipment. It is available in multiple package types, including TO-92, TSOP-5, SOIC-8, and Micro8 surface mount packages, and is compliant with RoHS standards. The MC34164D-5R2 is particularly noted for its temperature-compensated reference and internal clamp diode for discharging delay capacitors, making it a reliable choice for engineers seeking a compact and efficient reset solution.
