1 Functional Diagram

2 General Description

The US90A/91A 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 the

connectivity with any external interface such as

hardware monitoring or Super I/O IC easier.

These features are combined with the Melexis

patented no-V_DDdesign to fit the IC in small 4-pin

VK and VA package.

The device is also delivered in DC package for

automatic assembly.
