Краткое описание:
12-Channel Automotive 40-V High-Side LED Driver with FlexWire Interface
Дополнительная информация
The TPS929121-Q1 is a 12-channel, 40-V high-side LED driver designed for automotive lighting applications. It features 8-bit output current control and 12-bit PWM duty cycles per channel. The device utilizes the FlexWire interface, a UART-based communication protocol designed to meet strict EMC requirements over long distances by using an industry-standard CAN physical layer. It includes integrated diagnostics for LED open-circuit, short-to-ground, and single-LED short-circuit conditions, alongside a programmable EEPROM for flexible configuration and a watchdog timer for fail-safe operation.
