CrossChip CC6404
CC6403/4 is a one-chip solution for driving single-coil brushless DC fans and motors ， which is fabricated with innovative high voltage BiCMOS process. It includes high sensitivity hall sensor, chopper stabilized amplifier, dynamic offset cancellation, thermal protection and a low RDSON full bridge driver. With the benefit of the advanced process, the chip consumed power is very low, just only 2mA, much smaller than the drivers fabricated by bipolar process.| Part No. | CC6404 |

GENERAL DESCRIPTION
Its robustness perfectly suits for consumer applications. CC6403/4 has auto-restart function. When the fan is mechanically blocking, IC will shutdown the coil current and restart every time until the blocking release. Thus, the current flow the coil is low enough and protect the fan from over-heating. CC6403/4 can withstand the instantaneous 40V high voltage to ensure the reliability of the fan in various application environments. CC6403 has Speed counting function (Tachometer Output FG), CC6404 has Locking alarm function (Alarm Output RD). CC6403/4 is available in two packages, which are SOT89-5 and SOT335. The operation temperature range is -40~125°C.FEATURES
