BTS5566G集成電路（IC）的LED驅(qū)動器規(guī)格書PDF中文資料

BTS5566G屬于集成電路（IC）的LED驅(qū)動器。由英飛凌科技股份公司制造生產(chǎn)的BTS5566GLED 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?？蓪ζ骷ぷ鼽c進行外部控制，可在照明應(yīng)用中用于實現(xiàn)調(diào)光功能。

Overview

The SPOC - BTS5566G is a five channel high-side smart power switch in PG-DSO-36-34 package providing embedded protective functions. It is especially designed to control standard exterior lighting in automotive

applications. It is designed to drive lamps up to 3*27W + 2*10W. Configuration and status diagnosis isdone via SPI. Additionally, there is a current sense signal available for each channel that is routed via a multiplexer to a single diagnosis pin. The SPOC - BTS5566G provides a fail-safe function via limp home input pin.
