With this kwarg, multiple sensors can be used on one bus without fiddling with the ADDR/SDA line. Each sensors VCC has to be connected to a GPIO pin. Sensors can then be enabled one by one, setting a new address each time. Up to 4 sensors can be used on one bus this way.

With the kwarg
addr_reg, multiple sensors can be used on one bus without fiddling with the ADDR/SDA line. The sensors ADDR register is set to its value upon initialization.Each sensors VCC has to be connected to a GPIO pin. Sensors can then be enabled one by one, setting a new address each time. Up to 4 sensors can be used on one bus this way.
Example, VCC of TLV493Ds connected to D4 and D17:
It's surely not as nice of an API as it could be, but I didn't really have a better idea on an easy way to get multiple sensors working.
