General Description

Key Specification

BD94130MUF-M/BD94130EFV-M are embedded 24-

channel 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. Communication with μ-controller via SPI is

feasible.
