Fan-Speed Regulators and Monitors with SMBus/I2C-Compatible Interface

General Description The MAX6650/MAX6651 fan controllers use an SMBus/I2C-compatible interface to regulate and monitor the speed of 5VDC/12VDC brushless fans with built in tachometers. They automatically force the fan’s tachometer frequency (fan speed) to match a preprogrammed value in the Fan-S

风扇转速调节器和监控器，带有SMBus™/I²C兼容接口

MAX6650/MAX6651风扇控制器使用SMBus/I²C兼容接口来调节和监控带内置转速计的5VDC/12VDC无刷风扇的速度。它们使用外部MOSFET或双极性晶体管来线性调节风扇两端的电压，从而自动强制风扇的转速计频率（风扇转速）与风扇转速寄存器中的预编程值相匹配。MAX6650通过监控其转速计输出来调节单个风扇的转速。MAX6651也可以调节单个风扇的转速，但它包含额外的转速计输入，可以监控多达四个风扇，并在并行使用时将它们作为一个单元进行控制。\n\n MAX6650/MAX6651提供通用输入/输出(GPIO)引脚，用作数字输入、数字输出或各种硬件接口。这些开漏输入/输出 • 适用于5V/12V风扇的闭环/开环风扇速度控制\n\n• 2线SMBus/I²C兼容接口\n\n• 监控转速计输出\n• 单个转速计(MAX6650)\n\n• 多达四个转速计(MAX6651)\n\n\n\n\n• 可编程警报输出\n\n• GPIO\n\n• 硬件全开覆盖\n\n• 同步多个风扇\n\n• 四个可选从机地址\n\n• 电源电压：3V至5.5V\n\n• 小型封装\n• 10引脚µMAX (MAX6650)\n\n• 16引脚QSOP (MAX6651);
