Overview
The SGM4056 is a cost-effective, fully integrated high input voltage single-cell Li-Ion battery charger. The charger uses a CC/CV charge profile required by Li-Ion battery. The charger accepts an input voltage up to 26.5V but is disabled when the input voltage exceeds the OVP threshold, typically 6.8V (SGM4056-6.8) or 10.5V (SGM4056-10.5), to prevent excessive power dissipation. The 26.5V rating eliminates the overvoltage protection circuit required in a low input voltage charger.
Applications
- Mobile Phones
- Blue-Tooth Devices
- PDAs
- MP3 Players
- Stand-Alone Chargers
- Other Handheld Devices
Key features
- The charge current and the end-of-charge (EOC) current are programmable with external resistors.
- When the battery voltage is lower than typically 2.55V, the charger preconditions the battery with typically 18% of the programmed charge current.
- When the charge current reduces to the programmable EOC current level during the CV charge phase, an EOC indication is provided by the CHG pin, which is an open-drain output.
- An internal thermal foldback function protects the charger from any thermal failure.
- Two indication pins (PPR and CHG) allow simple interface to a microprocessor or LEDs.
- When no adapter is attached or when disabled, the charger draws less than 1μA leakage current from the battery.
