Special care must be taken not to put two MLX90615 devices with the same SD addresses on the
same bus as MLX90615 does not support ARP[1].
The MD can force the MLX90615 into low consumption mode “sleep mode”.
8.4.2 Differences with the standard SMBus specification (reference [1])
There are eleven command protocols for the standard SMBus interface. The MLX90615 supports only two of
them. Not supported commands are:
Supported commands are:
8.4.3 Detailed description
The SDA pin of the MLX90615 can operate also as a PWM output, depending on the EEPROM settings. If
PWM is enabled, after POR the SDA pin is directly configured as a PWM output. The PWM mode can be
avoided and the pin can be restored to its Serial Data function by issuing SMBus request condition. If SMBus
is the POR default, the request does not have to be sent.
All conditions on the SCL and SDA/PWM lines are described in detail below.
