The US79KUA is the most advanced Smart Fan Control Hall IC. It is designed for 5V and 12V cooling commutation. The chip contains many features to allow survival in a harsh environment. The IC was designed to eliminate all discrete components such as capacitors, resistors, transistors, diodes, PC board and associated labor, replacing US$0.25 to US$0.35 in direct cost.

The K rating guarantees proper operation up to an ambient temperature of 125°C. Hall IC circuitry and power FET output provide a low power dissipation cool chip.

Locked Rotor conditions are detected by the IC when there is no motion for one second and will shut off the motor drive for five seconds. Then, the IC will turn on the drive current for one second. This sequence continues indefinitely until the locked rotor condition is fixed. This feature prevents overheating.

Features and Benefits
  • Built-in Reverse Voltage Protection
  • Built-in RFI Filter
  • Power Efficient CMOS and Power MOSFET Drivers allow 400mA without overheating
  • Built-in Zener Diodes Protect Outputs
  • Eliminates all Fan Components
  • Eliminate PC Board
  • 5V and 12V Operation
  • High Sensitivity for switching symmetry
  • Locked Rotor Shutdown
