BD18354MUF-M
車用2ch定電流/電壓控制器，帶SPI和I2C介面
BD18354MUF-M是一個2通道定電流電壓控制器。內建高側電流檢測放大器。PWM調光佔空比可透過內建PWM產生電路自由設定。PWM調光透過驅動外部P通道FET實現。BD18354MUF-M可透過SPI編程10位元暫存器，支援單獨的10位元類比調光和10位元PWM調光，用於LED電流。BD18354MUF-M可透過設定MODE引腳，無需SPI通訊，從EEPROM讀取資料啟動。如果SPI通訊出現錯誤，BD18354MUF-M將支援LIMP-HOME模式和STAND-ALONE模式。在LIMP-HOME模式下，它透過載入連接的EEPROM中儲存的暫存器設定來操作。在STAND-ALONE模式下，可透過外部引腳設定單獨的LED電流，並可在施加輸入電源時保持LED電流輸出，無需SPI通訊。
