Working Principle of MAX8868ETEV+

The MAX8868ETEV+ is a linear PMIC with integrated high-side and low-side voltage regulation, battery monitoring and cell balancing, and reverse battery and short-circuit protection. It is designed to provide accurate voltage and current regulation in battery-operated systems.

The MAX8868ETEV+ features a high-side buck regulator, a low-side buck-boost converter, and a 3-cell lithium-based battery monitor (3CBM) circuit. The high-side buck regulator provides up to 5A of current, while the low-side buck-boost regulator provides up to 3A. The 3CBM circuit monitors the voltage of up to three cells in parallel, and can be used to enable cell balancing and battery management.

The MAX8868ETEV+ also provides reverse battery and short-circuit protection in order to protect the system from unexpected faults. When the device detects a short-circuit or reverse battery condition, it will automatically shut down to protect the system.

Conclusion

The MAX8868ETEV+ is a highly integrated linear PMIC designed for battery-powered applications. It provides precision high-side and low-side voltage regulation, accurate battery monitoring and cell balancing, and reverse battery and short-circuit protection. The MAX8868ETEV+ is ideal for portable medical, consumer health, and wearables applications with multiple power sources.
