BD9422EFV 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. BD9422EFV 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 BD9422EFV is available for the fail-safe design over a wide range output voltage.
6ch Constant LED drivers, available 400mA drive per 1ch.
Constant current accuracy ±1.8% (IC only)
Each 6ch external PWM inputs can control independent dimming .
Current Analogue (linear) dimming by VREF
1ch boost controller with current mode (external FET)
Several protection functions
DCDC part : OCP/OVP/UVLO/TSD
LED driver part :OPEN,SHORT detection
SHORT detection voltage is set by LSP terminal. Error detection output FAIL terminal inside (normal=Open, error=Drain)
Master/Slave mode inside
