Figure 18. Half-Bridge Current Limitation
OFFSET CHOPPING
If bit OFC_EN in the H-Bridge Control Register (HBCTL) is
set, HB1 and HB2 will continue to switch on the low-side
MOSFETs with the rising edge of the FGEN signal and HB3
and HB4 will switch on the low-side MOSFETs with the falling
edge on the FGEN input. In step motor applications this
feature allows the reduction of EMI due to a reduction of the
Coil Current

H-Bridge low-side
MOSFET will be switched
off if select current limit is
reached.
H-Bridge low-side
MOSFET will be turned on
with each rising edge of
the FGEN input.
