TLE71851EXUMA1

The TLE71851EXUMA1 from Infineon is an automotive grade 3-phase bridge driver in 36 pin DSO package. This robust low cost 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. It is especially designed for low battery voltage and therefore specified down to 5.5V supply voltage. Typical applications are cooling fan, fuel pump, water pump, oil pump, electro-hydraulic and electric power steering. The TLE7185-1E is designed for 12V power net.
