Комментарии об отличиях

BQ76920 ↔ SC8815

BQ76920: 3-5 cell battery AFE, 14/16-bit ADC, I2C/SPI, internal cell balancing (5mA), LDO 3.3V/5V, current sense 1mΩ shunt, alert pin, TQFN-20. SC8815: bidirectional buck-boost charger, QFN-32, VBAT 2.7-36V, I2C, 10-bit ADC, external N-MOSFETs (4 switches). ОТЛИЧИЯ: (1) SC8815 — charger controller с power conversion, BQ76920 — monitoring AFE без power path; (2) SC8815 требует external MOSFETs для power stage, BQ76920 имеет internal balancing FETs; (3) разрешение ADC 10-bit vs 14/16-bit; (4) карта регистров I2C полностью разная. Замена возможна только если требуется charger+monitoring, но НЕ как pure AFE replacement. Требуется адаптация firmware и добавление external power stage.
