TLE7183QU
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, electrohydraulic 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.
