概览

ADM1030 是一款符合 ACPI 标准的两沟道数字温度计和温度过低/过高报警器，用于计算机和热管理系统。该器件提供的更高 1°C 准确度针对 Pentium® III 而优化，让系统设计人员能够安全降低温度保护带，提高系统性能。脉宽调制 (PWM) 风扇控制输出通过变化输出占空比来控制冷却风扇的速度。占空比值介于 33%-100% 之间，可对风扇进行平滑控制。风扇的速度可使用 tach 输出，通过风扇的 TACH 输入进行监控。TACH 输入可编程为模拟输入，允许通过感应电阻确定 2 线风扇的速度。该器件还会检测失速的风扇。专用风扇速度控制环路即使在没有 CPU 软件的干预之下也能提供控制。它还会确保 CPU 或系统锁定时，风扇仍然可以基于温度测量值进行控制，风扇速度可进行调节以校正系统温度中的任何变化。风扇速度还可使用现有的 ACPI 软件进行控制。
