3. Increase the V_Testmode voltage level to 7.4 V and Vpower_in to 6.2 V. Now, left click “Write OTP
Values” from the GUI. This will program the OTP bits of a blank device with user-configured values.
CAUTION
Never exceed Vpower_in beyond 6.5 V in any circumstances to prevent
damaging the EVM.
4. In order to ensure that OTP are programmed properly, step 4 provides a means for read-back option.
To enable read-back, first reduce the V_Testmode voltage level back to 6.2 V and Vpower_in to 5.0 V
and left click “Read OTP Values”. If the GUI does not give any error message, it ensures the correct
OTP programming. This means the device is ready to be used in stand-alone mode at the end-
application circuit.
5. The final test to ensure proper OTP programming, power down both power supplies, disconnect the
USB2ANY. Reconnect the motor to EVM and reapply 6.2 V and 5.0 V, don’t connect USB2ANY and
open the jumper J1 on motherboard. The motor will start rotating confirming that the OTP are
programmed and device is ready to use.
NOTE:
The DRV10963 blank version is not available off-the-shelf for direct purchase, contact TI
sales or distributors for further details if custom settings for production with a blank version is
desired.
