Maximum number ofMLX90615 devices on one bus is 127, higher pullup currents are recommended for higher number of devices, faster busdata transfer rates, and increased reactive loading of the bus.MLX90615 is always a slave device on the bus. MLX90615 can work in both low-power and high-power SMBuscommunication.All voltages are with respect to the Vss (ground) unless otherwise noted.3901090615 Page 7 of 30 Data SheetRev 00128/Aug/2008
