Dual Ideal Diode Power Management Module with LM66200, 1.6 V to 5 V Input, 2.5 A Output and Automatic Power Source Switchover
The 7Semi LM66200 Dual Ideal Diode Module is a compact and efficient power management solution designed to automatically select between two power sources while maintaining uninterrupted power delivery to the load. Built around the Texas Instruments LM66200 dual ideal diode controller, the module supports input voltages from 1.6 V to 5 V and load currents up to 2.5 A. Its low-loss MOSFET-based architecture provides significantly lower voltage drop and higher efficiency than conventional diode OR-ing circuits, making it ideal for battery-powered and low-voltage systems.
The module continuously monitors both input supplies and automatically switches to the higher available voltage without interruption, ensuring reliable operation in battery backup, redundant power supplies, and portable electronic devices. Integrated reverse current protection prevents unwanted backflow between power sources, improving system safety and reliability. Its compact form factor allows easy integration into embedded electronics, IoT devices, robotics, medical equipment, and industrial control systems.
