Automotive exterior rear light Automotive exterior headlight Automotive interior ambient light Automotive cluster display3 Description
With increasing demand for animation in automotive lighting,LEDs must becontrolledindependently Therefore. LED drivers withdigitalinterfaces are essential to effectively drive pixel-controlled lighting applications. In exteriorlightingmultiple lamp functions are typically located on different PCB boards with off-board wires connected to each otherIt is diticuit for a traaitionasingle-ended intertace to mee the strict EMC requirements. Byusing anindustrial standard CAN physical laverthe UART-based FlexWire interface of the TPS******-Q1easily accomplishes long distance off-board communication without impacting EMC.
The TPS******-Q1 is a **-channel**-Vhigh-side LED driver that controls the *-bit output current and**-bit PWM duty cycles. The device meetsmultiple regulation requirements with LED open-circuitshort- to-ground,and single LED short-circuit diagnostics.A configurable watchdog also automatically sets fail- safe states when the MCU connection is lostand with programmable EEPROMTPS******-Q1can flexibly be set for different application scenarios.
