49 ADT7476 and ADT7490 chip family. The ADT7473 and ADT7475 differ only in
56 The ADT747x uses the 2-wire interface compatible with the SMBus 2.0
58 temperatures and two (2) or more voltages. It has four (4) 16-bit counters
62 A sophisticated control system for the PWM outputs is designed into the
63 ADT747x that allows fan speed to be adjusted automatically based on any of the

116 The ADT747x has a 10-bit ADC and can therefore measure temperatures
117 with a resolution of 0.25 degree Celsius. Temperature readings can be
121 The datasheet is very detailed and describes a procedure for determining
125 -----------------
129 - point1: Set the PWM speed at the lower temperature bound
130 - point2: Set the PWM speed at the higher temperature bound
135 PWM outputs, and a given PWM output can be controlled by several temperature
136 channels. As a result, the ADT747x may compute more than one PWM value
137 for a channel at a given time, in which case the maximum value (fastest
143 At Tmin - hysteresis the PWM output can either be off (0% duty cycle) or at the
145 `pwm[1-*]_stall_disable sysfs attribute`. A value of 0 means the fans will shut
146 off. A value of 1 means the fans will run at auto_point1_pwm.
150 set the value in ms in the `temp[1-*]_smoothing` sysfs attribute.
