BD94130EFV-M Datasheet | ROHM

Description BD94130MUF-M/BD94130EFV-M are embedded 24channel constant current drivers with 12bit PWM dimming and max 8-line switch controllers. This device can set LED constant current value by setting external ISET resistor. munication with μ-controller via SPI is feasible.
