ROHM Product Detail

BD18354MUF-M
2ch带SPI和I2C接口的恒流/电压控制器(车载用)

BD18354MUF-M是2ch恒流恒压控制器。内置高边电流检测放大器。PWM调光占空比可以通过内置PWM发生电路自由设定。通过驱动外部P-ch FET来实现PWM调光。BD18354MUF-M通过SPI编程10位寄存器,可以支持LED电流的独立10位模拟调光和10位PWM调光。BD18354MUF-M可以在没有SPI通信的情况下,通过设置MODE引脚,从EEPROM读取数据启动。如果SPI通信出现错误,BD18354MUF-M将支持LIMP-HOME模式和STAND-ALONE模式。在LIMP-HOME模式下,它通过加载存储在连接的EEPROM中的寄存器设置来运行。在STAND-ALONE模式下,可以通过外部引脚设置独立的LED电流,并且在施加输入电源时,无需SPI通信即可保持LED电流输出。
