The DRV89xx-Q1 can alternatively be used for the mirrors targeting the mirror-fold, mirror x-y direction control and side indicator LED's as shown in Figure 135.
The half-bridges are connected in parallel to support the higher current requirement of the mirror fold application. Whereas, single half-bridges can be used for driving the low-current motors used for the mirror X and Y positioning. Moreover, the LED's used in side indicators, puddle lamp is lower current which can be easily driven by single half-bridges.
The driver is powered by the automotive battery with a 3.3-V regulated power supply generated for the supplying power to the digital pin (VDD). A micro-controller is connected to the DRV89XX-Q1 device with the SPI interface (4-lines) for control, configuration and diagnostics. The device operating or sleep state is controlled by the nSLEEP pin and nFAULT pins is used as an additional hardware diagnostics.
