Linear Chargers
HMI’s linear chargers feature a small size, simple to use, and fully programmable ICs to charge batteries. The linear charger ICs are great for noise-sensitive and space-limited applications. They provide all necessary functions to charge a battery in terms of two CCs (pre-charge and fast charge), CV, termination, auto-recharge, dual inputs (USB and wireless), and battery protection.
