is it OK to use TUSB8041 without EEPROM and without SPI configuration? What does the default configuration looks like?

    Hi Hanno,

    If the TUSB8041 is used without EEPROM or SMBUS, the device configurations are set by the pin states sampled immediately after reset completes.  The pins (FULLPWRMGMTz, GANGED, PWRCTLx, PWRCTL_POL, etc) set the power management mode, battery charging enable and power control polarity.
