A6278ELWTR-T規(guī)格書詳情

A6278ELWTR-T屬于集成電路(IC)的LED驅(qū)動器。由Allegro MicroSystems制造生產(chǎn)的A6278ELWTR-TLED 驅(qū)動器器件屬于 LED 驅(qū)動器電源管理集成電路 (PMIC) 系列,可通過標稱固定電壓的電源為負載(通常為發(fā)光二極管)提供電流,并且電流可控。它與用于電壓調(diào)節(jié)的類似產(chǎn)品的主要區(qū)別在于,這類器件提供較低的反饋電壓(以提高系統(tǒng)能效),而且通常可對器件工作點進行外部控制,可在照明應用中用于實現(xiàn)調(diào)光功能。

Description

The A6278 and A6279 devices are specifically designed for LED display applications. Each of these BiCMOS devices includes a CMOS shift register, accompanying data latches, and NPN constant-current sink drivers. The A6278 contains 8 sink drivers, while there are 16 in the A6279.

The CMOS shift register and latches allow direct interfacing with microprocessor-based systems. With a 3.3 or 5 V logic supply, typical serial data-input rates can reach up to 25 MHz. The LED drive current is determined by the user’s selection of a single resistor. A CMOS serial data output permits cascading between multiple devices in applications requiring additional drive lines. Open LED connections can be detected and signaled back to the host microprocessor through the SERIAL DATA OUT pin.

Features and Benefits

? 3.0 to 5.5 V logic supply range

? Schmitt trigger inputs for improved noise immunity

? Power-On Reset (POR)

? Up to 90 mA constant-current sinking outputs

? LED open circuit detection

? Low-power CMOS logic and latches

? High data input rate

? 20 ns typical staggering delay on the outputs

? Internal UVLO and thermal shutdown (TSD) circuitry
