OUT8 – HS
on/off
If a bit is set the selected
output driver is switched
on. If the corresponding
PWM enable bit is set
(Input Register 1) the
driver is only activated if
PWM1 (PWM2) input
signal is high. The outputs
of OUT1-OUT5 are half
bridges. If the bits of HS-
and LS-driver of the same
half bridge are set, the
internal logic prevents that
both drivers of this output
stage can be switched on
simultaneously in order to
avoid a high internal
current from VS to GND.
In test mode (CSN>9.5V)
this bit combinations are
used to multiplex internal
signals to the DO-output.

OUT8 – HS
over-current
In case of an over-current
event the corresponding status
bit is set and the output driver
is disabled. If the over-current
Recovery Enable bit is set
(Input Register 1) the output
will be automatically
reactivated after a delay time
resulting in a PWM modulated
current with a programmable
duty cycle (Bit 21).
If the over-current recovery bit
is not set the microcontroller
has to clear the over-current
bit (Reset Bit) to reactivate the
output driver.
