The CC6402A is a high-performance, single-coil, brushless DC motor (fan) driver chip. This chip is manufactured using an innovative advanced high-voltage BiCMOS process, 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 CC6402A 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 CC6402A 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 jamming process and ensuring that the fan will not burn out during a stall, greatly improving the reliability of the fan. The CC6402A can withstand a momentary high voltage of 40V, ensuring fan reliability in various application environments. The CC6402A integrates reverse connection protection, eliminating the need for an external reverse connection protection diode, saving customers costs. The CC6402A is available in TO-94 and SOT335 packages and operates over a temperature range of -40~125°C.
