transition of the actual fan operation as the desired fan speed changes. The Update Time is set as
shown in Table 6.33.

Fan Configuration 2 Register
The Fan Configuration 2 Register controls the tachometer measurement and advanced features of the
RPM based Fan Speed Control Algorithm.
Bit 6 - EN_RRC - Enables ramp rate control when the fan driver is operated in the Direct Setting mode
or the Direct Setting with LUT mode.
‘0’ (default) - Ramp rate control is disabled. When the fan driver is operating in Direct Setting mode
or Direct Setting with LUT mode, the PWM setting will instantly transition to the next programmed
setting.
‘1’ - Ramp rate control is enabled. When the fan driver is operating in Direct Setting mode or Direct
Setting with LUT mode, the PWM setting will follow the ramp rate controls as determined by the
Fan Step and Update Time settings. The maximum PWM step is capped at the Fan Step setting
and is updated based on the Update Time as given by Table 6.33.
Bit 5 - GLITCH_EN - Disables the low pass glitch filter that removes high frequency noise injected on
the TACH pin.
‘0’ - The glitch filter is disabled.
‘1’ (default) - The glitch filter is enabled.
Bits 4 - 3 - DER_OPT[1:0] - Control some of the advanced options that affect the derivative portion of
the RPM based Fan Speed Control Algorithm as shown in Table 6.35. Note that the default derivative
options disable the ramp rate control maximum step settings. To take advantage of the full ramp rate
control, limit derivative options to the disabled or basic derivative settings.
