The CC6403/4 is a high-performance single-coil DC brushless motor (fan) driver IC. This IC is manufactured using an innovative advanced high-voltage BiCMOS process, which is optimized for Hall sensors and motor drives. The chip includes a high-sensitivity Hall sensor, a chopper offset cancellation module, a Hall temperature compensation unit, a voltage regulator, and a low RDSON full-bridge driver, etc. The CC6403/4 has low power consumption, with a static current of only 2mA, far lower than similar products on the market, helping to improve fan efficiency and reliability. The CC6403/4 integrates a stall protection function. When the fan stalls, it automatically stops supplying power to the coil and enters the self-start state, thereby reducing power consumption during the fan stall process, ensuring that the fan will not burn out during a stall, greatly improving the reliability of the fan. The CC6403/4 can withstand a momentary high voltage of 40V, ensuring the reliability of the fan in various application environments. The CC6403 has a speed counting function (FG), and the CC6404 has a lock-rotation alarm function (RD). The CC6403/4 is available in SOT89-5 and SOT335 packages, with an operating temperature range of -40~125°C.
