Description
The TLE7189F 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 high output performance and combines it with typical automotive specific requirements like full functionality
even at low battery voltages. Its 3 high side and 3 low side output stages are powerful enough to drive MOSFETs
with 400nC gate charge with approx. 150ns fall and rise times.
