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

風(fēng)扇轉(zhuǎn)速調(diào)節(jié)器和監(jiān)控器，帶有SMBus?/I2C兼容接口

MAX6650/MAX6651風(fēng)扇控制器使用SMBus/I2C兼容接口來(lái)調(diào)節(jié)和監(jiān)控帶內(nèi)置轉(zhuǎn)速計(jì)的5VDC/12VDC無(wú)刷風(fēng)扇的速度。它們使用外部MOSFET或雙極性晶體管來(lái)線性調(diào)節(jié)風(fēng)扇兩端的電壓，從而自動(dòng)強(qiáng)制風(fēng)扇的轉(zhuǎn)速計(jì)頻率（風(fēng)扇轉(zhuǎn)速）與風(fēng)扇轉(zhuǎn)速寄存器中的預(yù)編程值相匹配。MAX6650通過(guò)監(jiān)控其轉(zhuǎn)速計(jì)輸出來(lái)調(diào)節(jié)單個(gè)風(fēng)扇的轉(zhuǎn)速。MAX6651也可以調(diào)節(jié)單個(gè)風(fēng)扇的轉(zhuǎn)速，但它包含額外的轉(zhuǎn)速計(jì)輸入，可以監(jiān)控多達(dá)四個(gè)風(fēng)扇，并在并行使用時(shí)將它們作為一個(gè)單元進(jìn)行控制。\n\n MAX6650/MAX6651提供通用輸入/輸出(GPIO)引腳，用作數(shù)字輸入、數(shù)字輸出或各種硬件接口。這些開漏輸入/輸出 ? 適用于5V/12V風(fēng)扇的閉環(huán)/開環(huán)風(fēng)扇速度控制\n\n? 2線SMBus/I2C兼容接口\n\n? 監(jiān)控轉(zhuǎn)速計(jì)輸出\n? 單個(gè)轉(zhuǎn)速計(jì)(MAX6650)\n\n? 多達(dá)四個(gè)轉(zhuǎn)速計(jì)(MAX6651)\n\n\n\n\n? 可編程警報(bào)輸出\n\n?
