This driver can facilitate low power consumption by direct PWM or PWM constant current control. There are various built-in protection circuits in this IC. It is possible to output an abnormal detection signal for Wired-OR that notifies each protection circuit operation, and this contributes to set high reliability.\u003c\/p\u003e\n\u003ch3\u003eConstant Current Mode or Direct PWM Mode Selection\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstant Current Mode:\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eBy default, this project works in constant current mode.
