Power-Output 7 (Mirror heater driver)
Output 7 is a high-side switch intended to drive ohmic loads like the heater of an exterior
mirror.
4.5.1
Protection and Diagnosis
4.5.1.1
Short Circuit of Output to Ground
If the high-side switch is turned on and the current rises above the shutdown threshold
I
SD for longer than the shutdown delay time tdSD, the output transistor is turned off and
the corresponding diagnosis bit is set. During the delay time, the current is limited to
I
SC
as shown in Figure 13.

Short circuit protection
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
Open Load
For the high-side switches, an open-load in OFF-state scheme is used as shown in
Figure 14. The output is pulled up by a current source
I
OpL. In OFF-state, the output
voltage is monitored and compared to the threshold
V
OpL. If the voltage rises above this
threshold, the open-load signal is set to high. This is equivalent to comparing the load
resistance to the value
V
OpL / IOpL. The open load error bit is latched and can be reset
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.
