Description

The TLE7183QU driver IC is designed to control 6 to 12 external MOSFETs forming the converter for high current

3 phase motor drives in the automotive sector. It includes features like short circuit detection, 2-bit error diagnosis

and high output performance. It meets the typical requirements of automotive applications, e.g. full functionality

even at low battery voltages. Its 3 high side and 3 low side output stages are powerful enough to drive MOSFETs

with a gate charge of 400 nC with rise and fall times of approximately 150 ns.

Typical applications are cooling fan, water pump, electro-hydraulic and electric power steering. The TLE7183QU

is designed for a 12 V power net.

Several options are available for the fixed short circuit detection level.
