Engine Cooling Fans

Belt-driven cooling fans will soon be a way of the past. For better fuel efficiency, battery and engine cooling fans are now controlled electronically—and our power ICs are designed with decades of expertise in efficiently controlling the electric motors in these applications. Plus, our brush and brushless motor controller ICs and power management ICs are all designed and qualified for the demanding under-hood environment.

Check out our BLDC MOSFET pre-driver ICs for brushless motors, full-bridge MOSFET pre-driver ICs for brush motors and power management ICs for powertrain electronic control modules.
