OUT6 OC
Recovery Enable
After 50ms the bit can be cleared.
If over-current condition still exists, a
wrong load can be assumed.
OUT11 – 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.

OUT11 PWM1
Enable
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. OUT9
and OUT10 is controlled by PWM2
input all other outputs are controlled
by PWM1 input.
