Part Information Review and Datasheet Update

flux

Reviewed the parametric symbol grouping and updated the findings in MAX77961BEFV12+ Datasheet, Symbol, and Footprint Review.
Summary: the grouping is usable but not fully library-quality. Main issues: STBY should not be in Status/Interrupt, DISQBAT should be Hardware Control, AVL/PVL should be Bias Supplies, CSINP/CSINN should be CHGIN/Input Current Sense, and BST/LX pins should be Switching Power Stage rather than generic Power Input.

Fix the symbol sections and pin groupings to match the datasheet.

flux

I’ll apply the recommended datasheet-aligned section and pin group names across all 30 terminals, then verify the resulting symbol organization.

flux

Fixed the parametric symbol organization across all 30 terminals.
Updated sections and pin groups now follow the datasheet functional blocks: CHGIN / Input Current Sense, Switching Power Stage, System / Battery Power Path, Hardware Control, Charger Programming, Bias Supplies, I2C Communication, Status / Interrupt Outputs, Thermal / Battery Monitor, and Ground. Verified afterward, and the relevant terminal review checks returned no issues.

  • Voltage Regulator IC 1 Output 30-FC2QFN (4x4)
The MAX77960B/MAX77961B are high-performance wide-input 3A (MAX77960B)/6A (MAX77961B) buckboost chargers with Smart Power Selector™ and operate as a reverse buck converter without an additional inductor, allowing the ICs to power USB on-the-go (OTG) accessories. The devices integrate low-loss power switches and provide high efficiency, low heat, and fast battery charging in a small solution size. The reverse buck has true load disconnect and is protected by an adjustable output current limit. The devices are highly flexible and programmable through I2C configuration or autonomously through resistor configuration. The battery charger includes the Smart Power Selector to accommodate a wide range of battery sizes and system loads. The Smart Power Selector allows the system to start up smoothly when an input source is available even when the battery is deeply discharged (dead battery) or missing. For battery safety/authentication reasons, the ICs can be configured to keep charging disabled, and allow the DC-DC to switch and regulate the SYS voltage. The system processor can later enable charging using I2C commands as appropriate. Alternatively, the ICs can be configured to automatically start charging.
