Output Stages

The 3 low side and 3 high side powerful push-pull output stages of the TLE7183F are all floating blocks, each with

its own source pin. This allows the direct connection of the output stage to the source of each single MOSFET,

allowing a perfect control of each gate-source voltage even when 200A are driven in the bridge with rise and fall

times clearly below 1µs.

All 6 output stages have the same output power and thanks to the used charge pump principle they can be

switched all up to 30kHz.

Its output stages are powerful enough to drive MOSFETs with 400nC gate charge with approx. 150ns fall and rise

times or even to run 12 MOSFETs with 200nC each with fall and rise times of approx. 150ns.

Maximum allowed power dissipation, max. junction temperature and the limited current capabilities of the charge

pump limit the use for higher frequencies.

Each output stage has its own short circuit detection block. For more details about short circuit detection see

Chapter 5.2.1.
