BD82A26MUF-ME2 Image

The BD82A26MUF-ME2 from ROHM Semiconductor is an Automotive Qualified 6-Channel White LED Driver IC that has been designed for LCD backlight systems. It requires an input voltage of 3.0-48 V. This AEC-Q100-qualified LED driver consists of a low-side FET/pre-driver, circuits for DC/DC control logic, PWM comparator, error amplifier, minimum channel selector, and current driver. It includes six channels for current drivers to drive the inputs of the LED driver, making it suitable for high-brightness LED drive applications. The LED driver IC uses a PWM signal to control the dimming, and also supports analog dimming to accommodate even higher brightness ranges when combined with PWM-based dimming. It provides current mode boost output using boost DC-DC converters.

This LED driver IC integrates under voltage lockout (UVLO), over-voltage protection (OVP), temperature-shutdown protection (TSD), LED anode/cathode short-circuit protection (Anode/Cathode), LED open/short protection (LED Open/Short), and over-current protection (OCP) to prevent false triggers or over-heating-related damages. It is available in a surface-mount package that measures 5 x 5 x 1 mm and is ideal for automotive small/medium-sized LCD panels, cluster panels, head-up display (HUD), and automotive center information display (CID) panel navigation applications.
