| ROHM Begins Shipping BD81A76EFV-M Samples
| Supports 12-inch LCD panels with 6-channel output
| Contributed to the platformization of LCD panel control boards

Recently, the adoption of LCD panels in automotive navigation systems, instrument clusters, and head-up displays (HUDs) is being rapidly promoted in the automotive sector to improve visibility and aesthetics. The enlargement of panels is also occurring simultaneously.

Accordingly, the requirements for the number of lights and brightness of LCD backlight LEDs are becoming more diverse, and LED drivers are required to include multi-channel operation, advanced dimming, and prevention of LED flicker.

Accordingly, ROHM announced on the 21st that it has developed the LED driver IC 'BD81A76EFV-M' for automotive LCD backlights.

BD81A76EFV-M is an LED driver IC for automotive LCD backlights with 6-channel output (120mA/ch) capable of supporting 12-inch class LCD panels.

The BD81A76EFV-M employs ROHM's step-up/step-down control technology to widely support LCD panel applications.

For example, when compared with a 6-channel output LED driver, a standard product that uses only boost control cannot drive 6 channels × 6 to 10 LEDs (36 to 60 LEDs). On the other hand, the new product can support 6 channels × 1 to 10 LEDs (6 to 60 LEDs).

This allows for broad support with a single LED driver, not only for large LCD panels but also for small and medium-sized LCD panels, contributing to the platformization of LCD panel control boards considering model expansion.

In addition, while typical 4-channel output products can only handle LCD applications up to the 8-inch class, this product can handle applications of the 10- to 12-inch class. Through ROHM’s patented PWM dimming technology, a dimming ratio of 10,000:1 (@100Hz) for LEDs suitable for center information displays (CID) and cluster panels is achieved, contributing to improved visibility and aesthetics in automotive LCD panel applications.

The BD81A76EFV-M achieves a standby current of 10µA and complies with the automotive reliability standard 'AEC-Q100'. It is also equipped with a spectrum spreading function for EMI countermeasures and satisfies the international standard 'CISPR 25' for noise in the automotive sector.

The BD81A76EFV-M, suitable for driving backlight LEDs for 12-inch class LCD panels used in automobiles such as car navigation systems, CIDs, cluster panels, HUDs, electronic mirrors, and small and medium-sized LCD panels, began sample shipments at 800 yen per unit in July 2019 and is scheduled to begin mass production with a production capacity of 100,000 units per month starting in October 2019.
