Description

The TLE7188F 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. 150 ns fall and rise times.

Typical applications are cooling fan, water pump, electro-hydraulic and electric power steering. The TLE7188F is

designed for 12 V power net.
