Fan Controller and Remote Temperature Sensor with SMBus Serial Interface

General Description The MAX1669 fan controller includes a precise digital thermometer that reports the temperature of a remote sensor. The remote sensor is a diode-connected transistor—typically a low-cost, easily mounted 2N3906 PNP type—replacing conventional thermistors or thermocouples. Remote

风扇控制器及远端温度传感器，带有SMBus串行接口

MAX1669风扇控制器包含一个高精度的数字温度计，可报告远程传感器的温度。远程传感器是一个二极管连接式晶体管（通常为低成本、易于安装的2N3906 PNP型），可取代传统的热敏电阻或热电偶。对于多个制造商的晶体管来说，远程精度为±3°C，无需校准。MAX1669具有独立的风扇控制器，其低电流逻辑输出需要外部电源元件来与直流无刷风扇进行接口。风扇控制器有两种工作模式：用于驱动风扇电机的低频（20Hz至160Hz）PWM模式，或产生可变直流控制电压的高阻抗DAC输出。在PWM模式下，FAN频率可同步至一个外部时钟。\n\n 其他主要特性包括用于风扇存在检测的通用输入/输出(GPIO)， • 测量远程CPU温度\n\n• 无需校准\n\n• 用于风扇的20Hz至160Hz PWM输出\n\n• PWM频率同步输入(260kHz)\n\n• 灵活的风扇接口：线性或PWM\n\n• SMBus 2线串行接口\n\n• 可编程欠温/过温警报\n\n• 反ALERT锁存中断输出\n\n• 反OVERT恒温器输出\n\n• 两个GPIO引脚\n\n• 一次写入配置保护\n\n• 支持SMBus警报响应\n\n• ±3°C温度精度（-40°C至+125°C，远程）\n\n• 3µA待机电源电流\n\n• 电源电压范围：+3V至+5.5V\n\n• 小型16引脚QSOP封装\n\n• 远程二;
