Panasonic offers LED drivers that save board space and development time.
Full-color LEDs available Provide the 24-channel type (AN37775A) as key products. The 9-channel type
(AN37777A) is also available for small board that does not have enough space for wires.
Data transfer type selectable based on the number of LEDs, preventing transfer delay between drivers Address selection type: AN37777A and AN37775A
24-channel type (AN37775A): IIC or SPI selectable
Built-in LDO that reduces the parts count (AN37775A, AN37777A) The LED power supply can be used to power the IC, thereby reducing the number of wires, harnesses, and connectors
Easy to collectively adjust the brightness of LEDs (AN37775A, AN37777A) The software-controlled brightness adjustment reduces the time to develop software,
allowing you to easily design amusement applications with user-adjustable brightness control.
High ESD noise immunity Provide a circuit to prevent logical errors due to transient voltage drop, simplifying the
design of applications.
