MBI6329 ∣ FALD LED Backlight Driver IC ∣ Automotive Lighting ∣Macroblock



48-Channel LED Driver with 1:8 Time-Multiplexing

MBI6329Q is an advanced 48-channel high power constant current full-array local dimming (FALD) backlighting LED driver. It is designed to support up to 1:8 time-multiplexing and control up to 384 LED dimming zone applications using internal Pulse Width Modulation (PWM) control with selectable 14 / 13 / 12-bit color depth and independent current dimming control (of each LED current sink) to improve contrast ratio for HDR applications.

The embedded S-PWM technology easily reduces the flickers and improves the image fidelity when MBI6329Q displays.

Both compulsory and real-time LED error open/short detection and protection are included during both start-up and regular operation. Besides, MBI6329Q also provides DC/DC feedback control, ghost elimination function, and over-temperature protection features.
