Product Description

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 over-voltage protection circuit required in a low input voltage charger.
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.
The SGM4056 is available in Green TDFN-3×3-8L, TDFN-2×3-8L, TDFN-2×2-8L and SOIC-8 (Exposed Pad) packages and is rated over the -40℃ to +85℃ temperature range.
