... SPD pin. ComDel - Adjusts the Commutation Delay The ZXBM1017 has a fixed internal commutation delay of 100us, however, there may be cases where this needs to be adjusted to a different value. A resistor can be attached to this pin to enable the delay to be lengthened or shortened dependant upon application ...
