Maxim Integrated MAX6384SX23 Microprocessor Reset Circuit

The MAX6384SX23 from Maxim Integrated is a highly reliable and precise microprocessor (µP) supervisory circuit designed to maintain system integrity during power failures or unexpected events. This compact and efficient device is an essential component for any system that requires a robust level of protection for its microprocessor.

The MAX6384SX23 operates by monitoring the supply voltage and ensuring that it remains above a predefined threshold. If the voltage drops below this critical level, the device generates a reset signal that lasts a minimum of 140ms, ensuring that the µP has sufficient time to return to a safe state before resuming normal operation. This feature is crucial for preventing system errors and data corruption that can occur during power instability.

One of the key features of the MAX6384SX23 is its low power consumption, which makes it an ideal choice for battery-powered applications. With a supply current of only 1.2µA, this reset circuit contributes to the overall power efficiency of the system, helping to extend battery life and reduce energy costs.

The device is offered in a compact, surface-mount SOT/µSOT package, making it suitable for space-constrained applications. It supports a wide operating temperature range from -40°C to +125°C, allowing it to function reliably in harsh environmental conditions. The MAX6384SX23 also includes a manual reset input, providing a convenient way for users to initiate a system reset when needed.

Furthermore, the MAX6384SX23 features an active-low, push-pull reset output, which provides a strong signal to the µP for immediate response. This design eliminates the need for external pull-up resistors, simplifying the circuit design and saving board space.

In summary, the MAX6384SX23 from Maxim Integrated is a versatile and energy-efficient solution for µP system stability. Its precise voltage monitoring, low power consumption, and robust feature set make it a top choice for engineers looking to enhance the reliability of their electronic systems.
