Overview
With the increasing demand for animation in automotive lighting, LEDs must be controlled independently. Therefore, LED drivers with digital interfaces are essential to effectively drive pixel - controlled lighting applications. In exterior lighting, multiple lamp functions are typically located on different PCB boards with off - board wires connected to each other. It is difficult for a traditional single - ended interface to meet the strict EMC requirements. By using an industrial - standard CAN physical layer, the UART - based FlexWire interface of the TPS929240 - Q1 easily accomplishes long distance off - board communication without impacting EMC. The TPS929240 - Q1 is a 24 - channel, 40V high - side LED driver that controls the 8 - bit output current and 12 - bit PWM duty cycles. The device meets multiple regulation requirements with LED open - circuit, short - to - ground, and single LED short - circuit diagnostics. A configurable watchdog also automatically sets FAILSAFE states when the MCU connection is lost, and, with programmable EEPROM, TPS929240 - Q1 can flexibly be set for different application scenarios.
