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.
