Table 5 Electrical specification parameters of the MLX90615 (continued)

Notes: All the communication and refresh rate timings are given for the nominal calibrated HFO frequency and

will vary with this frequency’s variations.

*SMBus compatible interface is described in details in the SMBus detailed description section. Maximum

number of MLX90615 devices on one bus is 127, higher pull-up currents are recommended for higher number of devices,

faster bus data 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 SMBus

communication.

All voltages are with respect to the Vss (ground) unless otherwise noted.
