4.5
Output 7 is a high-side switch intended to drive ohmic loads like the heater of an exterior
mirror.
4.5.1
4.5.1.1
If the high-side switch is turned on and the current rises above the shutdown threshold
I
the corresponding diagnosis bit is set. During the delay time, the current is limited to
as shown in
Figure 13
The output stage stays off and the error bit set until a status register reset is sent to the
SPI or a power-on reset is performed.
4.5.1.2
For the high-side switches, an open-load in OFF-state scheme is used as shown in
Figure
voltage is monitored and compared to the threshold
threshold, the open-load signal is set to high. This is equivalent to comparing the load
resistance to the value
by the SPI status register reset or by a power-on reset.
The pull-up current can be switched on and off by the OpLxON bits. This bit should be
set to LOW (i.e. pull-up current switched off) if an output is used to drive LEDs because
they may emit light if biased with the pull-up current.
