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. All PWM timing specifications are given for single PWM output (factory default for MLX90614xAx). For the extended
PWM output (factory default for the MLX90614xBx) each period has twice the timing specifications (refer to the PWM
detailed description section). 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 7.6, “Switching between PWM and SMBus communication” for
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 MLX90614xxx devices on
one bus is 127, higher pullup currents are recommended for higher number of devices, faster bus data transfer rates, and
increased reactive loading of the bus.
MLX90614xxx is always a slave device on the bus. MLX90614xxx can work in both low-power and high-power SMBus
communication.
All voltages are referred to the Vss (ground) unless otherwise noted.
Power saving mode is not available on the 5V version (MLX90614Axx).
