The EVAL6460 controlled by the EVAL_IBU-STR7 AN3097
14/34 Doc ID 16599 Rev 2
3. nAwake driving source (refer to the L6460 section - nAWAKE pin)
Figure 9. nAwake driving source
Here in the "master" position, place it in the alternative position on the board used as slave.
4. Awake input (refer to the L6460 section - nAWAKE pin)
Figure 10. Awake input
This jumper must be closed on the master board, in this way the nAWAKE pin can be driven
by the EVAL_IBU-STR7 board.
5. Stepper current sense resistor value
Figure 11. Stepper current sense resistor value
You can choose a different sense resistor value according to your application requirements.
Bridge 3 and 4 have three resistors available connected in parallel with value: 1 Ω, 2.2 Ω and
3.9 Ω.. By default these jumpers are all closed, and the resulting sense resistor is about 0.6
Ω.
