ON Semiconductor MC33164P-5RAG Voltage Supervisor IC

The ON Semiconductor MC33164P-5RAG is a precision voltage supervisor integrated circuit (IC) designed to monitor voltage levels within electronic systems, ensuring reliable operation and protection against undervoltage conditions. This particular model is housed in a compact DIP-8 (Dual In-line Package) and is engineered to maintain system integrity through its fast response to voltage fluctuations.

Key Features

• Voltage Threshold: The MC33164P-5RAG is programmed with a precise factory-set threshold voltage of 4.55V, which is ideal for 5V applications. This ensures that the system is closely monitored for any deviations from the nominal operating voltage.
• Reset Timeout: Upon detection of an undervoltage condition, the device provides a significant delay time before issuing a reset signal, allowing the power supply to stabilize. This delay is typically 140ms, which helps to avoid nuisance resets due to transient voltage dips.
• Low Power Consumption: It is designed for energy efficiency, consuming minimal power. This feature makes it suitable for use in portable and battery-operated devices where power conservation is crucial.
• Open-Collector Reset Output: The reset output is an open-collector configuration that can sink current, allowing it to interface with a variety of logic families and drive external components if necessary.
• Temperature Range: The device operates over an industrial temperature range from -40°C to +85°C, making it reliable in a wide range of environmental conditions.

Applications

The MC33164P-5RAG is versatile and can be employed in numerous applications where voltage supervision is critical. It is commonly found in microprocessor/microcontroller systems, computers, controllers, and intelligent instruments. Its role is to ensure that these systems operate within their specified voltage range, providing a reset signal to the processor in the event of an undervoltage condition, which can prevent system errors and data corruption.

Overall, the ON Semiconductor MC33164P-5RAG is an essential component for maintaining the health and stability of electronic systems, offering robust features in a small package that can be easily integrated into a variety of designs.
