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.
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.
