BA829 is a 5-line serial-in / parallel-out driver from ROHM. It can drive a maximum of 300mA current of LED and has features such as low standby current and cascading connection. It is mainly used in AV equipment such as component stereo sets, videos and TV sets, PCs and control microcontroller mounted equipment.
This technical note describes the BA829 serial‑in/parallel‑out driver, a constant‑current output driver with an integrated shift register and latch. It details electrical characteristics, recommended operating conditions, pin functions, and ordering information for designers.
Key features include a maximum output current of 300 mA, support for up to eight LEDs via a five‑line interface, separate digital and power grounds, and a built‑in standby function. The document also provides absolute maximum ratings, timing charts, and application notes for reliable circuit design.
