TI Team,
Is it possible to configure high-side breaking in DRV8703D-Q1 / DRV8702D-Q1 ?
Customer needs:
Datasheet is confusing:
Hi Piotr,
To operate with the customer's conditions, MODE=Hi-Z (with current regulation). During current regulation, LOW side FET is enabled during the TOFF when current regulation is active. As noted in the image below from the datasheet, current regulation will only work when driving in high-side configuration (other motor terminal connected to GND). If you plan on driving in low-side configuration (motor connected between SH and VM), MODE=1 is recommended.
Unfortunately it is not possible to recirculate current through the HIGH side FET when current regulation is enabled (MODE=Hi-Z).
This is a typo on the datasheet. Current regulation is disabled when MODE=1.
Regards,
Pablo Armet
