TLE7185-1E

3相桥式驱动器IC 3-Phase Bridge Driver IC

Description:

The is a driver IC dedicated to control the 6 to 12 external MOSFETs forming the converter for high current 3 phase motor drives in the automotive sector. It incorporates features like short circuit detection, diagnosis and combines it with typical automotive specific requirements. The TLE7185-1E is especially designed for low battery voltage and therefore it is specified down to 5.5V supply voltage. Typical applications are cooling fan, water pump, electro-hydraulic and electric power steering. The TLE7185-1E is designed for 12V power net.
