PRODUCTION DATA
Analog input based motor control can be configured by setting SPD_CTRL_MODE to 00b. In this mode, the duty command (DUTY CMD) varies with the analog voltage input (VSPEED) on the SPEED/WAKE pin or DACOUT/SOx/SPEED_ANA pin (configurable via DAC_SOX_ANA_CONFIG) VSPEED. When 0 < VSPEED < VEN_SB, DUTY CMD is set to zero and the motor is stopped. When VEN_SB < VSPEED < VANA_FS, DUTY CMD varies linearly with VSPEED as shown in #GUID-B27547AD-41E8-4454-9E76-67BDD54D8890 . When VSPEED > VANA_FS, DUTY CMD is clamped to 100%.
With DACOUT/SOx/SPEED_ANA pin used as the analog control input, the SLEEP/WAKE pin can be independently used to control the sleep or standby entry and exit as described in Table 7-3
