8.5.2 Request condition
If PWM is enabled, the MLX90615’s SMBus Request condition is needed to disable PWM and reconfigure
SDA/PWM pin before starting SMBus communication. Once disabled, PWM can only be enabled by
switching the supply Off-On. The MLX90615’s SMBus request condition requires forcing the SCL pin LOW for
a period longer than the request time (t
8.5.3 PWM is disabled
If PWM is disabled by means of EEPROM the SDA/PWM pin is directly used for the SMBus communication
after POR.
