ON Semiconductor MC34164P-5 Microprocessor Voltage Monitor

The ON Semiconductor MC34164P-5 is a precision voltage monitor tailored for microprocessor applications, ensuring reliable system performance by monitoring the supply voltage. This integrated circuit (IC) is designed to trigger a reset in microprocessors when the supply voltage drops below a predetermined value, thereby protecting the system from uncertain operation at low voltages.

One of the key features of the MC34164P-5 is its low threshold voltage of 4.55V, which is ideal for 5V powered circuits. This ensures that the microprocessor and related peripherals are reset when the supply voltage falls approximately 10% below the nominal operating voltage. The device's precision voltage sensing capability is critical for systems that require consistent and accurate monitoring to prevent data corruption and ensure the integrity of the operation.

The MC34164P-5 comes in a compact DIP-8 (Dual In-line Package) making it suitable for through-hole mounting, which is beneficial for prototyping and applications where space is not a limiting factor. Its versatility is further enhanced by an operating temperature range of -40°C to +85°C, allowing it to function reliably in a wide range of environmental conditions.

Additional features of the MC34164P-5 include a low supply current, which is a significant advantage for power-sensitive applications. The device also offers an active-low reset output, which remains asserted for a period after the supply voltage has returned to an acceptable level, ensuring the microprocessor has adequate time to reinitialize.

Overall, the ON Semiconductor MC34164P-5 is an essential component for any microprocessor-based system that demands a reliable power supply monitoring solution. Its precision, low power consumption, and ease of integration make it a popular choice for designers and engineers looking to enhance the stability and robustness of their electronic systems.
