US62 General Description
The US62 is a one-chip solution for driving two-coil brushless DC cooling fans.
Based on the advanced Melexis CMOS process, the IC contains a Hall-effect sensor, dynamic offset correction and low side output drivers.
The Frequency Generator open-drain output makes easier the connectivity with any external interface such as hardware monitoring or Super I/O IC.
These features are combined with the Melexis patented no-VDD design to fit the IC in a small 4-pin VK package.
