RPM-Based Fan Controller with HW Thermal Shutdown  
Datasheet  
The Pushed Temperature Registers store user programmed temperature values that can be used by  
the look-up table to update the fan control algorithm. Data written in these registers is not compared  
against any limits and must match the data format shown in Table 6.3.

Register  
The TRIP_SET Voltage Register stores data that is measured on the TRIP_SET Voltage input. Each  
bit weight represents mV of resolution so that the final voltage can be determined by adding the  
weighting of the set bits together.

Ideality **  
These registers store the ideality factors that are applied to the external diodes.  
The External Diode 3 channel will use the settings for the External Diode 2 channel.  
Beta Compensation and Resistance Error Correction automatically correct for most diode ideality  
errors, therefore it is not recommended that these settings be updated without consulting SMSC.  
Only the lower three bits can be written. Writing to any other bit will be ignored.  
The Ideality Factor Registers are software locked.
