9 Application and Implementation
NOTE
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI's customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
The DRV10975 is used in sensorless 3-phase BLDC motor control. The driver provides a high performance, high
reliability, flexible and simple solution for appliance fan, pump, and HVAC applications. The following design in
Figure 39 shows a common application of the DRV10975. For the DRV10975Z sleep mode device, a Zener
diode must be placed in parallel with the 10-µF VREG capacitor as shown in Figure 39. The Zener diode must
meet the requirements listed in Table 11
