MM4009

Load switch IC is switch IC that have power supply line ON/OFF control and overcurrent protection. In addition to overcurrent protection, it also has built-in protection such as reverse current protection, making it appropriate for protecting power systems in a variety of applications.

Outline

This IC is load switch IC with built-in overcurrent protection function suitable for HDMI requirements (5V, 300mA) and other applications. Supports load currents up to 300mA, and when the output current to the load exceeds threshold, it switches to constant current operation and limits the output current to protect the load or input device from abnormal conditions. It also has a built-in soft start function to suppress inrush current and prevent voltage drop, and built-in function to prevent reverse current when the output voltage exceeds the input voltage, making it possible to protect the input device. Certified to the safety standard IEC62368-1, it is appropriate for protecting power system circuits in a variety of applications.
