Auto-OCP/Fan Curve 智能校正电流过流与风扇温控曲线

如何达到智能校正过电流保护点 (Auto-OCP)

※传统生产流程
INT 机台定 20A (举例) 准位 后, 人工调整可变电阻至设定点后点胶固定。

▲缺点
VR 调整需要额外人力, 且胶体易因时间或环温变化而产生质变, 或 VR 脱落…等等
◎ 极创方案(IC 与系统专利)
1. Housekeeping 内置 (IN1Txx 系列) INFSitronix Smart-auto-trim™ algorithm
2. IC 自动 ON-LINE 侦测设计电流并记录值

◎优点 (自动化生产)
1.维持原生产流水线, 仅需加装刻录治具
2.免除 VR 成本与风险
3. 省掉 OCP 调整时间
