5.1.1
The 3 low side and 3 high side powerful push-pull output stages of the TLE7185-1E 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 below 1µs.
All 6 output stages have the same output power and thanks to the used bootstrap principle they can be switched
all up to 30kHz.
To ensure high gate voltages even at low battery voltages, the driver IC has an integrated charge pump. It allows
operation of normal level MOSFETs down to 5.5V supply.
Each output stage has its own short circuit detection block. For more details about short circuit detection see

The TLE7185-1E provides a feature tailored to the requirements in 12V automotive applications. Often the
operation of an application has to be assured even at 9V supply voltage or lower. Normally bridge driver ICs
