TYPICAL APPLICATIONS
The following figure shows a typical automotive lighting
application (only one vehicle corner) using an external PWM
clock from the main MCU. A redundancy circuitry has been
implemented to substitute light control (from MCU to
watchdog) in case of a Fail-safe condition.
It is recommended to locate a 22 nF decoupling capacitor
to the module connector.
