Current monitor

Following current image
(1/10.000) of the HS driver
will be multiplexed to CM
output:
Temperature
warning
This bit is for information
purpose only. It can be used
for a thermal management by
the microcontroller to avoid a
thermal shutdown.
10
Not ready bit
After switching the device from
standby mode to active mode
an internal timer is started to
allow charge pump to settle
before the outputs can be
activated. This bit is cleared
automatically after start up
time has finished. Since this bit
is controlled by internal clock it
can be used for synchronizing
testing events (e.g. measuring
filter times).

OUT5 - 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 PWM input
signal is high. The outputs of
OUT1-OUT3 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.
OUT5-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 13).
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.

registers. If bit 14 (disable

load status will be ignored.
