3 說明
在汽車儀表板及其他安全性能至關(guān)重要的 LED 驅(qū)動器 應(yīng)用中，為了確保 LED 亮度與色溫的一致性，針對多通道 LED 的性能需求日益提升。系統(tǒng)級安全考量因素要求檢測各種故障情況，因此會加深系統(tǒng)的復(fù)雜程度。
TLC6C5712-Q1 器件是一款 12 通道恒定灌電流 LED 驅(qū)動器。憑借 8 位點校正功能和高精度輸出電流，TLC6C5712-Q1 器件成為校正 LED 亮度和色溫變化的理想解決方案。該器件針對每個組件提供高級保護和診斷功能，可提升系統(tǒng)級穩(wěn)定性并簡化面向安全的設(shè)計。六個具有可編程映射功能的 PWM 輸入支持多種 LED 顏色調(diào)光配置并提供高調(diào)光比率。具有診斷功能的 16 位串行外設(shè)接口 (SPI) 支持以菊花鏈方式連接多個器件并簡化系統(tǒng)級設(shè)計。
