Drives the external high-side and low-side switching MOSFETs to step down the voltage for battery charging.
OZ8681L / 8681L QFN16 - контроллер заряда - ICishka 8681l ic datasheet
: It typically utilizes two high-side current sensors to maintain accurate monitoring of the energy flow into and out of the battery cells. icishka.com Technical Specifications Drives the external high-side and low-side switching MOSFETs
This is the most common trap area. Do not assume the chip is faulty just because it has power. Use an oscilloscope to monitor the control signal (e.g., LOT6_CHG ) that enables the IC's main power supply. This signal comes from the EC or another logic controller. If it is not present, the EC may be preventing charging due to another fault (e.g., a communication error with the battery). a communication error with the battery).
