2通道温度监测器，提供双路、自动PWM风扇速度控制器

MAX6639可以监视自身温度和一路外部连接成二极管的晶体管温度，或两路外部连接成二极管的晶体管温度，这种晶体管通常内置于CPU、FPGA或GPU。2线串口采用标准的系统管理总线(SMBus™)，可执行写字节、读字节、发送字节以及接收字节命令，以读取温度数据、设置报警门限。可在任意时刻通过SMBus读取温度数据，三个可编程报警输出用于产生中断、禁止或高温关断信号。\n\n 内部双路PWM风扇转速控制器根据温度数据可调节两个冷却风扇的转速，系统运行在致冷状态时能够将风扇噪声降至最小，而在功耗上升时还可提供最大的致冷效果。通过风扇转速反馈实现速率调节，以便控制风扇转速，而不仅仅是PWM占 • 两个热敏二极管输入\n• 高达25kHz的PWM输出频率\n• 三个可选择的SMBus地址\n• 本地温度检测\n• 1°C远程测量温度精度\n• 两个PWM输出用于风扇驱动(开漏，可上拉至+13.5V)\n• 可编程风扇控制\n• 自动风扇旋转确保风扇启动\n• 受控的转速变化确保平稳的风扇转速调节\n• ±3%风扇转速测量精度\n• 温度检测始于POR，具有系统失效保护\n• /OT和/THERM输出用于禁止或关断控制\n• 测量温度高达+150°C\n• MAX6639F针对n = 1.021进行优化，实现Penryn兼容;
