5.1.1
The 3 low side and 3 high side powerful push-pull output stages of the TLE7189QK 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 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
