The ON Semiconductor MC33164-5R2G is a precision voltage supervisor integrated circuit (IC) designed to monitor voltage levels within electronic systems. This device is particularly crucial in applications where voltage monitoring is critical for the performance and safety of the system, such as in microprocessors, microcontrollers, and battery-operated equipment.

The MC33164-5R2G ensures that the voltages stay within predetermined thresholds, providing a reliable solution for system reset functions. It features a fixed-sense threshold voltage of 4.63V, which makes it suitable for 5V systems. Upon detecting an undervoltage condition, the IC generates a reset signal to the host system, thus protecting the system from operating under conditions that could lead to malfunction or damage.

This device comes in a compact surface-mount package, specifically the SOT-23-3, which allows for efficient space utilization on printed circuit boards (PCBs). The small form factor is ideal for space-constrained applications while still delivering robust performance. The MC33164-5R2G operates over a wide temperature range from -40°C to +85°C, ensuring reliable operation in diverse environments.

The key features of the MC33164-5R2G include a low supply current, which is beneficial for power-sensitive designs, and an open-drain reset output, which provides the flexibility to connect to various logic levels. Additionally, the device has a fast response time to undervoltage events, ensuring the system is quickly alerted to potential issues.

ON Semiconductor's commitment to quality means that the MC33164-5R2G is manufactured with the highest standards, ensuring reliability and performance consistency. This voltage supervisor IC is an essential component for designers looking to enhance the safety and reliability of their electronic systems, particularly in applications where precise voltage monitoring is a necessity.
