1 Functional Diagram

2 General Description

The US62/63 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.

Frequency Generator or Rotation Detection is

available. The 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-V_DDdesign to fit the IC in a small 4-

pin VK package.
