The MAX810JD is a precision microprocessor (µP) supervisory circuit designed by NXP Semiconductors to monitor power supplies in digital systems. It provides a significant level of system reliability and accuracy required in critical applications. This supervisory circuit ensures that the system's microprocessor is reset to a known state during power-up, power-down, or brown-out conditions.

Key Features

• Voltage Monitoring: The device keeps a vigilant eye on the system voltage levels, ensuring they remain within specified thresholds for reliable operation.
• Power-On Reset: It generates a reset signal when the power supply turns on, maintaining the reset for an adequate period after the supply has reached a stable condition. This ensures the microprocessor starts up correctly every time.
• Manual Reset: An additional feature includes a manual reset input that allows for an external trigger to initiate a system reset.
• Low Power Consumption: Designed for energy-sensitive applications, the MAX810JD operates with low power consumption, making it an ideal choice for portable and battery-powered equipment.
• Compact Package: Available in a small outline package, it is suitable for space-constrained applications, allowing for efficient use of PCB real estate.
