BQ25638 powers internal bias circuits from the higher voltage of VBUS versus BAT. When either voltage rises above its undervoltage lockout (UVLO) threshold, all registers are reset to their POR values and the I2C interface is enabled for communication. A non-maskable INT pulse is generated, after which the host can access all of the registers.
