Datasheet - Detailed Description
7.11 Period Offset
Period Offset register defines the offset which is added to the period counter to shift the switching frequency. It also provides some additional
control bits.
This offset is only activated when frequency tracking is stopped. An offset has been provided as some types of motors operate better at slightly
below mechanical resonance.
Table 14
provides an example for 25MHz master clock and 200kHz nomnal driver frequency. Period offset is only
supposed to lower drive frequency.
Idle mode reduces power consumption while preserving the most recent frequency calibration. To further reduce power, the XPD pin must be
pulled to ground.
7.12 Hybrid Speed Register
The hybrid speed register allows the average voltage as seen by the motor to be set fromVDD to 2 x VDD. This provides a power efficient
method of reducing the speed of the motor. The value of the register can vary from0 (half bridge) to 128 (full bridge). The average voltage can
be calculated in the following manner.
VAVG = VDD + (RegisterValue *VDD / 128)
(EQ 2)
Where:
VDD is the supply voltage
