Product Introduction
As the demand for animated effects in automotive lighting continues to grow, independent control of LEDs has become essential. Consequently, LED drivers with digital interfaces are critical for effectively driving pixel-controlled lighting applications. In exterior lighting, multiple lamp functions are typically located on different PCBs and interconnected via off-board wiring. Conventional single-ended interfaces struggle to meet stringent EMC requirements. The TPS929160-Q1's UART-based FlexWire interface leverages an industry-standard CAN physical layer, enabling long-distance off-board communication without compromising EMC performance.
The TPS929160-Q1 is a 16-channel, 40V high-side LED driver capable of controlling 8-bit output current and 12-bit PWM duty cycle. The device features LED open-circuit, short-to-ground, and single-LED short-circuit diagnostics to satisfy multiple regulatory requirements. A configurable watchdog automatically sets a fail-safe state upon loss of MCU connection, and through a programmable EEPROM, the TPS929160-Q1 can be flexibly configured to accommodate various application scenarios.
