Notes: All the communication and refresh rate timings are given for the nominal calibrated HFO frequency and
will vary with this frequency’s variations.
1. With large capacitive load lower PWM frequency is recommended. Thermal relay output (when
configured) has the PWM DC specification and can be programmed as push-pull, or NMOS open drain. PWM is
free-running, power-up factory default is SMBus, refer to section 8.6, “Switching between PWM and SMBus
communication” for more details.
2. For SMBus compatible interface on 12V application refer to Application information section. SMBus
compatible interface is described in details in the SMBus detailed description section. Maximum number of
MLX90614 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.
MLX90614 is always a slave device on the bus. MLX90614 can work in both low-power and high-power SMBus
communication.
All voltages are referred to the Vss (ground) unless otherwise noted.
Sleep mode is not available on the 5V version (MLX90614Axx).
