, often found as the , is a highly integrated SMBus programmable, multi-chemistry battery charge controller

Output Current: Designed to deliver high efficiency with output currents often reaching up to 2A or 3A.

Downloading the official datasheet is non-negotiable for several reasons:

| Symptom | Possible Cause | Datasheet Section to Consult | | :--- | :--- | :--- | | Battery charges but no output | Overdischarge lock – DO pin low | Section 6.2 (Discharge Control Logic) | | Output present but won't charge | Overcurrent latch – CO pin low | Section 6.4 (Charge Overcurrent Detection) | | IC runs hot | Excessive VDD voltage or short on VM | Section 4 (Absolute Maximum Ratings) | | Intermittent protection trips | Noise on VM pin – missing capacitor | Figure 9 (Recommended Layout) |

Download Resources: For the most accurate and safe documentation, we recommend downloading from reputable component databases rather than random file-sharing sites. You can typically find the PDF by searching:
