3 description
With the increasing demand for animation in the field of automotive lighting, it is necessary to
LED for separate control. Therefore, LED drive with digital interface
The filter is very important for effectively driving pixel controlled lighting applications. stay
In exterior lighting, multiple lamp functions are usually connected to each other by non onboard lines
On different PCB boards. The traditional single ended interface is difficult to meet the strict
EMC requirements. By using the industry common can physical layer,
Tps929120-q1 UART based flexible wire interface can be easily implemented
Now long-distance non onboard communication will not affect EMC performance.
Tps929120-q1 is a 12 channel 40V high side LED driver
It can control 8-bit output current and 12 bit PWM duty cycle. This device
The device has led open circuit, ground short circuit and single LED short circuit diagnosis functions,
It can meet a variety of adjustment requirements. Configurable when MCU connection is lost
The watchdog can also automatically set the fail safe status. With programmable
EEPROM can be flexibly set for different application scenarios
