Auto-OCP/Fan Curve 智能校正電流過流與風扇溫控曲線

如何達到智能校正過電流保護點 (Auto-OCP)

※傳統生產流程
INT 機台定 20A (舉例) 準位 後, 人工調整可變電阻至設定點後點膠固定。

▲缺點
VR 調整需要額外人力, 且膠體易因時間或環溫變化而產生質變, 或 VR 脫落…等等
◎ 極創方案(IC 與系統專利)
1. Housekeeping 內置 (IN1Txx 系列) INFSitronix Smart-auto-trim™ algorithm
2. IC 自動 ON-LINE 偵測設計電流並記錄值

◎優點 (自動化生產)
1.維持原生產流水線, 僅需加裝燒錄治具
2.免除 VR 成本與風險
3. 省掉 OCP 調整時間
