NY1 Lineup
LED Controller & Driver
NY1系列產品為單晶片CMOS的LED控制驅動合成IC。不需外加震盪電阻，每個Output可分別提供不同的電流輸出並搭配軟體電流控制來驅動不同亮度的LED，還可選擇定電流輸出以保護LED。閃燈合成方式可任意組成出各種閃爍方式，藉由製造過程中更換Code光罩，可將不同的閃燈資料寫入ROM中。用戶可使用簡便的 Q-Light 工具軟體來快速地進行開發。
特性：
- 寬廣的工作電壓： 1.6V ~ 6.4V。
- 最多有512個閃燈格(Step)，可規劃成32個閃燈組(Sentence)。
- 閃燈最多為5通道或7通道輸出(所有I/O都設為輸出腳)，每段方波還可分別定義成0%~100%不同的高度，讓LED產生漸明或漸暗的效果。
- 每個輸出腳都可分別設定為不同的電流。(光罩選擇)
- 特殊功能選項 ”雜訊觸發” (Noise-Trigger)。(此功能常見於電子打火機和手機天線的應用)
- 低壓復位(LVR) 選項，當電壓瞬間低於1.5V時，IC 會自動復位。(光罩選擇)
