Abstract

A current-mode control Li-ion battery charger is proposed in this paper. The main architecture adopts two-loop current-mode control in the constant current (CC) and the constant voltage (CV) stages. Compare to the voltage-mode control, the proposed architecture reduces the complexity significantly. Trickle-current mode provides complete battery charging process to protect the battery. The built-in battery resistance detector is proposed to achieve aging detection while charging. The proposed charger is fabricated in TSMC 0.35-μm process, achieving 78% power efficiency.
