US90A / US91A

24V Hall IC Fan Driver

Features and Benefits 

  • Low cost 
  • High sensitivity Hall Sensor 
  • Locked rotor protection and auto-restart 
  • Power-efficient CMOS and power MOSFETs 
  • Built-in output protection clamping diode 
  • Integrated tachometer (US90A) or alarm (US91A) signal output 
  • 2-coil fan driver with FG/RD output in 4-pin VK / VA and 8-pin narrow SOIC packages (all RoHS Compliant)

Application Examples 

  • 12V/24V fans 
  • Peak current up to 500mA

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-VDD design to fit the IC in small 4-pin VK and VA package. The device is also delivered in DC package for automatic assembly.
