#99170 - spi
Responding to: Ian Bell's previous message
The common way how to interface this kind of chips is an SPI-chain. In this way it is address-less (addressing requires extra pins -> cost) and virtually unlimited length of chain. See similar parts from Toshiba and Allegro or search back for the part Erik is using now.

PS Erik: the current regulation input, does it specifically require a resistor or a current source would do?
