Provide - Hall IC Fan Drivers - Technology [Veckway]

US90/US91 is a device that has twoUnipolar coilA single-chip solution for driving three wire fansIntegrated circuit58彩票The output driver has instantaneous protection that can be copied, and the logic output pin (FG/RD) is an open drain output. For the US90, it has a frequency generator (FG)/tachometer output, while for the US91, it has a rotation detection (Rp) output, which normally outputs a low level and outputs a high level when the Hall switch changes by less than 4Hz.
