Overview CCH477 is a high-performance, low-cost single-coil DC brushless motor (fan) driver IC. This IC is manufactured using an innovative advanced high-voltage BiCMOS process. The chip includes a high-sensitivity Hall sensor, chopper offset cancellation module, Hall temperature compensation unit, voltage regulator, over-temperature protection, and low RDSON full-bridge driver, etc. The CCH477 has low power consumption, with a static current of only 2.5mA, far lower than similar products on the market, which helps to improve fan efficiency and reliability. CCH477 only provides Class A products, reducing customer inventory costs. CCH477 uses a TO-94 package.
