5.1.1 Output Stages
The six powerful push-pull output stages of the TLE7183QU are floating blocks, each one of them with its own
source pin which can be directly connected to the source pin of an external MOSFET. This enables a perfect
control of each MOSFET’s gate-source voltage even if a current of 200A is driven in the bridge.
All output stages have the same high output power. A single output stage is able to drive a single MOSFET with
400nC gate charge (or two MOSFETs with 200nC) achieving rise and fall times of approx. 150ns.
They can be switched with a frequency of up to 30kHz. The usability at higher frequencies is limited by the
maximum allowed power dissipation, the max. junction temperature and the limited current capabilities of the
charge pump.
Each output stage has its own short circuit detection block. Please see Chapter 5.2.1 for short circuit detection
details.
