Lithium Battery Charging Series Product Introduction

Linear Charging Series Chips

Halo Microelectronics' linear charging product series features small chip size, simple operation, and easy programming to adjust charging parameters. Linear charging chips are very suitable for applications sensitive to noise and with limited space. These products integrate all necessary battery charging functions, including pre-charging, fast charging, constant voltage charging, charge termination, and automatic recharging. They also support dual input (USB charging and wireless charging) and battery protection functions.

Switching Charging Series Chips

Halo Microelectronics' switching charging product series offers programmable charging parameters, high charging efficiency, and automatic switching of charging states. This product series also provides automatic recharging and composite battery protection functions, and minimizes power loss when the input adapter voltage varies greatly.

Switched-Capacitor Charging Series Chips

Halo Microelectronics' switched-capacitor charging product series is well-known among customers for supporting 2C-4C battery fast charging. The independently developed dual-phase charging topology of Halo Microelectronics achieves extremely small voltage ripple under high-current charging. This product series has four different operating modes: forward 1:1 (bypass) and 2:1 CP, reverse 1:2 CP and 1:1 (bypass). It also supports applications in various system environments and can work with USB PD adapters to charge batteries safely and quickly.
