TLE7183F Description and Electrical Characteristics 5 Description and Electrical Characteristics 5.1 MOSFET Driver 5.1.1 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.

TLE7183F Description and Electrical Characteristics 5.1.2 Operation at Vs<12V - Integrated Charge Pumps The TLE7183F 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 provide in such conditions clearly less than 9V to the gate of the external MOSFETs, increasing their RDSon and the associated power dissipation.

TLE7183F 5.2 Protection and Diagnostic Functions 5.2.1 Short Circuit Protection The TLE7183F provides a short circuit protection for the external MOSFETs. It is a monitoring of the drain-source voltage of the external MOSFETs. As soon as this voltage is higher than the short circuit detection limit, a timer will start to run. The short circuit detection level is programmed fix in the chip.

TLE7183F 5.2.4 Undervoltage Shut Down The TLE7183F has an integrated undervoltage shut down, to assure that the behavior of the device is predictable in all supply voltage ranges. If the voltage of a charge pump buffer capacitors CBx reaches the undervoltage shut down level for a minimum specified filter time, the gate-source voltage of all external MOSFETs will be actively pulled to low.

If one or two ENAx pins is pulled to low for a specified minimum time, the error registers are cleared and the external MOSFETs are switched off actively. During disable only the errors undervoltage shut down and overtemperature warning are shown.

TLE7183F 5.3 Shunt Signal Conditioning The TLE7183F incorporates a fast and precise operational amplifier for conditioning and amplification of the current sense shunt signal. Additionally, one reference bias buffer is integrated to provide an adjustable bias reference for the three OpAmps. The voltage devider on the VRI pin should be less than 50 kOhm, the filtering capacitor less than 1.2 µF - if needed at all. The gain of the OpAmp is adjustable by external resistors within a range of 5 to 15.
