onsemi Supervisors MC33164P-003

The MC33164P-003 is a micropower undervoltage sensing circuit designed for use as a reset controller in portable microprocessor-based systems, particularly where extended battery life is essential. It operates with a guaranteed input voltage range down to 1.0 V and features an open collector reset output capable of sinking over 6.0 mA. The device includes a temperature-compensated bandgap reference, precise comparator thresholds, and built-in hysteresis to prevent erratic reset behavior. This product is available in multiple package types, including TO-92, TSOP-5, SOIC-8, and Micro8, making it versatile for various applications. It is suitable for monitoring 3.0 V or 5.0 V power supplies in appliances, automotive, consumer, and industrial equipment. The MC33164P-003 is also Pb-free and RoHS compliant, ensuring it meets environmental standards. With extremely low standby current consumption, as low as 9.0 µA, it is an economical solution for low voltage detection in battery-operated devices.
