The BD94130EFV-ME2 from ROHM Semiconductor is an Automotive Qualified 24-Channel Constant Current LED Driver that is ideal for cluster, center infotainment display, and other automotive backlight applications. This LED driver requires an input voltage of 3 - 5.5 V and provides an output current of up to 80 mA. It integrates PWM dimming function, constant current drivers, 4/6/8-line switch controllers, digital level shifters, feedback control, and protection circuitries, making it a highly reliable solution. This LED driver allows for easy setting of the LED constant current value using an external internal set resistor. It enables seamless communication with the μ-controller via a built-in serial peripheral interface (SPI) for added convenience. This AEC-Q100-qualified LED driver includes short-circuiting protection (SCP), over-voltage protection (OVP), LED open/short detection, and abnormality output indication to prevent over-load-related damages. It is available in a surface-mount package that measures 18.5 x 9.5 x 1 mm.
