Functional Features

• Overvoltage Protection: Monitors the input voltage and triggers a fault condition if it exceeds the set threshold.
• Undervoltage Protection: Detects when the input voltage falls below the specified threshold and initiates a fault condition.
• Overcurrent Protection: Monitors the load current and activates a fault condition if it surpasses the programmed threshold.
• Fault Reporting: Provides an open-drain output to indicate the occurrence of a fault condition.
• Enable Control: Allows for enabling or disabling the protection controller.
• Power Good Output: Indicates that the input voltage is within the acceptable range.

Advantages and Disadvantages

Advantages: - Wide operating voltage range enables compatibility with various power supply systems. - Robust protection against overvoltage, undervoltage, and overcurrent conditions ensures the safety of connected devices. - Low quiescent current minimizes power consumption. - Compact MSOP package allows for space-efficient integration into electronic systems.

Disadvantages: - Limited fault reporting options (open-drain output only). - Requires external components for complete power management system implementation.

Working Principles

The LM5067MM-1/NOPB operates by continuously monitoring the input voltage and load current. It compares these values against the user-programmed thresholds for overvoltage, undervoltage, and overcurrent conditions. If any of these thresholds are exceeded, the controller triggers a fault condition by activating the fault output and shutting down the power supply. The enable control input allows for manual enable/disable functionality, while the power good output provides an indication of the input voltage status.
