Engine Cooling

The engine cooling fan is a high duty cycle motor that gets used a lot. In city traffic the engine cooling fan may be on continuously. This application needs to be the most reliable for without it the engine can be ruined. ST is there with cost effective solutions. ST’s solutions CONTROL the most reliable engine cooling fan motors, the brushless motor. ST’s brushless ELECTRONICS COMPONENTS provide for a very reliable and cost effective solution utilizing the motor’s back EMF to detect rotor position avoiding the need for expensive, high temperature hall effect transistors. Providing solutions from the embedded MICROCONTROLLER to the power SWITCHES, from VOLTAGE regulation to the serial communications physical layer, ST has the answer for your engine cooling fan control needs
