All PWM timing specifications are given for single PWM output. With large capacitive loads, a 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. 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. The maximum number of MLX90616xxx 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. The MLX90616 is always a slave device on the bus. The MLX90616 can work in both low-power and high-power SMBus communication. All voltages are referred to the Vss (ground) unless otherwise noted. |
