AH9485 and AH9486 single phase, all-in-one, low noise smart motor driver family from Diodes Inc.

The AH9485/86 are single-chip motordriver ICs with an integrated HBridge switch and high-sensitivity Hall sensors for driving of small low-profile, single-coil, brushless DC motors and cooling fans.

The output stage "soft switching" minimizes acoustic switching noise and electromagnetic interference (EMI) providing a low noise solution. For system flexibility the family offers versatile DC Voltage and PWM speed control options.

The AH9485/86 features rotor lock detect, shutdown and automatic restart. The AH9485 features an open-drain Frequency Generator tachometer (FG) output, while AH9486 has a Rotation Detect alarm (RD) output, both to interface externally to monitor speed and rotation status.

They are packaged in the flat-pin TSOT26F package to help place the device in a PCB cut-out to minimize overall component height.

Applications

  • 5V BLDC cooling fans, motors, extractors and pumps
  • Notebook and desktop PCs cooling fans and blowers
  • Instrumentation and equipment power supply cooling fans
