The MC33164D-3R2 is an undervoltage sensing circuit designed for use as a reset controller in microprocessor-based systems, particularly where battery life is a concern. It operates with a wide input voltage range from 1.0 V to 10 V and features a bandgap reference, precise comparator thresholds, and built-in hysteresis to ensure stable reset operation. The device can sink over 6.0 mA at its reset output and has a low standby current of just 9.0 µA, making it suitable for power-sensitive applications. This supervisor is available in multiple package types, including TO-92, TSOP-5, SOIC-8, and Micro8, allowing for flexibility in design. It is particularly useful for monitoring 3.0 V or 5.0 V power supplies in various applications, including automotive, consumer, and industrial equipment. The MC33164D-3R2 is also RoHS compliant and Pb-free, aligning with modern environmental standards.
