Enable high
RDSon OUT7
After 50ms the bit can be
cleared. If over-current
condition still exists, a wrong
load can be assumed.
OUT8 – 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.

If the PWM1/2 enable bit is set
and the output is enabled
(input register 0) the output is
switched On if PWM1/2 input is
high and switched off if
PWM1/2 input is low. OUT7 is
controlled by PWM2 input. All
other outputs are controlled by
PWM1 input.
