The SGM41526YTQQ24G/TR is a stand-alone Li-Ion and Li-polymer battery charger IC from SG Micro Corp, operating at a 1.6MHz switching frequency. It integrates PWM switches and gate drivers for automatic power path selection between battery and adapter.
Key electrical specifications include a high charge efficiency of up to 95.2%, ±0.4% charge voltage regulation, and ±5% charge current regulation. The device supports an input operating voltage range of 4.5V to 22V with an absolute maximum rating of 30V. It also features Dynamic Power Management (DPM) to prevent input source overload.
Safety features include cycle-by-cycle current limit, thermal regulation, thermal shutdown, and input under-voltage lockout (UVLO). The SGM41526 variant can charge 2-, 3-, or 4-cell batteries with a 4.2V/cell setting, while the SGM41527 offers adjustable charge voltage. Battery pack temperature monitoring is also supported for safe charging.
