How Does IC_HG4054M5/TR Work?
The IC_HG4054M5/TR functions using a constant current/constant voltage (CC/CV) charging algorithm. The charging process occurs in the following stages:
1. Pre-Charge Stage
- If the battery voltage is below a certain threshold, the IC enters a pre-charge mode, where a small current is applied to the battery to protect it from damage.
2. Fast Charge (Constant Current Mode)
- Once the battery reaches the minimum threshold, the IC supplies a constant current (programmed using an external resistor) to rapidly charge the battery.
3. Constant Voltage Mode
- As the battery reaches the target voltage, the IC switches to constant voltage mode, reducing the charging current gradually to prevent overcharging.
4. Charge Termination
- When the charging current drops below a defined threshold (typically 10% of the full charge current), the IC automatically terminates charging to prevent battery overcharging.
5. Standby Mode
- After charging is complete, the IC enters standby mode, consuming minimal power and ensuring energy efficiency.
