Enable high
RDSon OUT5
After 50ms the bit can be cleared. If
over-current condition still exists, a
wrong load can be assumed.
OUT6 – 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.
3 ms) 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. OUT5 is
controlled by PWM2 input. All other
outputs are controlled by PWM1
input.
