BD83A04EFV-ME2

BD83A04EFV-ME2 is a 4 ch current driver integrated white LED driver IC for automotive and LCD backlight. It has MOS for boost and 4 ch current drivers for LED drive, making it ideal for high brightness LED drive. LED pin maximum voltage is 50V, making it suitable for driving medium LCD panels. The dimming is controlled by the PWM signal and can be set up to 20000 1 at 100Hz. It also supports analogue dimming and can accommodate even higher brightness ranges by combining with PWM dimming. DC/DC converter can be controlled for boost applications and the input operating voltage range is 4.5V to 48V. Application includes automotive CID (centre information display) panel, navigation cluster panel, HUD (head up display), other small and medium-sized LCD panel for automotive.
