8.1 Application Information
The TPS929160-Q1 device with FlexWire interface easily generates independent brightness and ON and OFF
control for large amount LED units. The device allows each single LED as a pixel in large LED array or string to
display a complicated pattern or animation under accurate control. The FlexWire interface also supports to use
the CAN physical layer through external CAN transceiver for data transmission between master microcontroller
(MCU) and TPS929160-Q1, which allows the TPS929160-Q1 to be controlled by control module far away in
long distance. With these features, the single TPS929160-Q1 or multiple TPS929160-Q1 devices can drive
large volume LEDs with digital control interface for automotive lighting applications. The long distance, reliable
off-board communication with high EMC performance simplifies the system design in lower cost for automotive
application.
The TPS929160-Q1 can also operate as a standalone LED driver without master MCU. The FAIL-SAFE state
is designed to ensure the TPS929160-Q1 keeps operating in case the communication is lost or the master
MCU is damaged. TPS929160-Q1 can also use the FAIL-SAFE state without master MCU design for traditional
automotive lighting applications.
8.2 Typical Application
8.2.1 Smart Rear Lamp with Distributed LED Drivers
Use multiple TPS929160-Q1 devices to control large number of LED pixels for rear-lamp animation.
