OUT5 OC
recovery enable
In case of an over-current
event the over-current
status bit (status register
0) is set and the output is
switched off. If the over-
current recovery enable bit
is set the output will be
automatically reactivated
after a delay time resulting
in a PWM modulated
current with a
programmable duty cycle
(Bit 13 of Input data
register 1).
Depending on occurrence
of overcurrent event and
internal clock phase it is
possible that one recovery
cycle is executed even if
this bit is set to zero.
Not ready bit
After switching the device
from standby mode to active
mode an internal timer is
started to allow charge pump
to settle before the outputs
can be activated. This bit is
cleared automatically after
start up time has finished.
Since this bit is controlled by
internal clock it can be used
for synchronizing testing
events(e.g. measuring filter
times).

OUT4 OC
recovery enable
0
Not used.

OUT3 OC
recovery enable
OUT5-HS
open-load
The open-load detection
monitors the load current in
each activated output stage. If
the load current is below the
open-load detection threshold
for at least 1 ms (tdOL) the
corresponding open-load bit
is set. Due to mechanical
/electrical inertia of typical
loads a short activation of the
outputs (e.g. 3ms) can be
used to test the open-load
status without changing the
mechanical/electrical state of
the loads.

OUT5 PWM
enable
If the PWM enable bit is
set and the output is
enabled (input register 0)
the output is switched on if
PWM input is high and
switched off if PWM input
is low.
