MAX31790 Description
The MAX31790 controls the speeds of up to six fans using six independent PWM outputs. The desired fan speeds (or PWM duty cycles) are written through the I2C interface. The outputs drive “4-wire” fans directly, or can be used to modulate the fan’s power terminals using an external pass transistor.
