BQ24193 Charge Controller Chip for Nintendo Switch

Description

The BQ24193 chip is a lithium-ion charge controller used on the Nintendo Switch motherboard. It plays a central role in battery management: voltage regulation, thermal safety, fast charging management, and communication with other components like the M92T36. In case of slow charging, absence of battery charging despite being plugged in, or power-related restarts, its replacement is often necessary to restore normal operation.
