ON Semiconductor MC34164D-005 Microprocessor Voltage Monitor

The MC34164D-005 is a precision undervoltage sensing integrated circuit from ON Semiconductor, designed to monitor the supply voltage of microprocessors (µP) and digital systems. It provides a critical function by ensuring that the system operates at adequate power levels, thus protecting the system from low voltage conditions that can lead to improper operation, data loss, or even hardware damage.

Key Features

• Voltage Threshold: The MC34164D-005 comes with a preset threshold voltage of 4.55V, which is ideal for 5V applications. This precise threshold ensures reliable monitoring for systems that cannot tolerate significant deviations from their intended operating voltage.
• Reset Output: It features an active-low reset output, which remains asserted until the VCC voltage exceeds the reset threshold voltage. The reset output remains operational with VCC as low as 1.0V, which is beneficial for systems that require a valid reset signal even during low voltage conditions.
• Low Power Consumption: This device is designed for low power consumption, making it suitable for power-sensitive applications. Its quiescent current is typically only 13 µA, which helps to minimize the overall power draw of the system it is monitoring.
• Fast Response Time: The MC34164D-005 reacts quickly to under-voltage conditions, providing a fast response time that is critical for protecting sensitive electronic components.
• Temperature Range: It operates over a wide temperature range from -40°C to +85°C, making it versatile for use in various environments and applications.
• Packaging: The device is available in an 8-pin SOIC package, which is suitable for surface mount technology (SMT) and occupies minimal space on a printed circuit board (PCB).

Applications

The MC34164D-005 is designed for use in a variety of applications where accurate voltage monitoring is critical. It is often utilized in microprocessor systems, computers, controllers, and intelligent instruments. Its ability to provide a reliable reset signal makes it an essential component in systems that require a controlled start-up and protection from low voltage conditions.

Overall, the ON Semiconductor MC34164D-005 is a robust and reliable solution for voltage monitoring in digital systems, ensuring that your electronics perform optimally by preventing undervoltage-related malfunctions.
