6ch boost LED driver which constant setting can be shared by I²C control - BD9423EFV

BD9423EFV is a high efficiency driver for white LEDs and designed for large LCD panel. This IC is built-in high current drive and high responsibility type 6ch LED drivers and 1ch boost DCDC converter. BD9423EFV has some protect function against fault conditions, such as the over-voltage protection (OVP), LED OPEN and SHORT protection, the over current limit protection of DCDC (OCP). Therefore BD9423EFV is available for the fail-safe design over a wide range output voltage. Moreover the functions and the detection voltage can be controlled by the I²C. This enables for the constant setting of external parts to be shared by I²C control, nevertheless the different usage condition.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
