the driver will be turned off and the Overcurrent / Short to
latched until the fault register is read via SPI. The driver will remain in the off condition
for the short circuit refresh time (see table below,
the driver will automatically turn on again. If the short condition is no longer present, the
channel will operate normally. If the short circuit condition persists, the driver will be
cycled off after the short sense time once again. The refresh time has been chosen for
minimal increase in power dissipation during a continuous fault condition.
In order to prevent false detection of an overcurrent / short to
on” transition of the low-side output transistor, the detection circuit is disabled for a
blanking time (see

The output transistor control circuit includes a current limit feature that will limit the
transistor current to a maximum value (see table below,
the device from excessive current flow.
If a new average current command or configuration command is received for a shorted
channel while that channel is within the short circuit refresh time, the new data will be
stored but the channel will remain in the off state until the refresh time expires. The new
data will become active when the short circuit condition is released.
