... The TLE6280GP is a driver IC dedicated to control the external Mosfets forming the converter for high current 3 phase motor drives in the automotive sector. It incorporates fea- tures like short circuit detection, diagnosis and high output performance and combines it with typical automotive specific requirements like full functionality even at low battery voltages ...

... The dead times generated in the TLE6280GP are adjustable. The dead time generated by the TLE6280GP can be varied from 100ns to 4µs by connecting an external resistor from the DT pin to GND. The dead time has to be long enough to avoid a short between battery and GND, while the dead time should be as short as possible to reduce extra power dissipation in the external Mosfets ...

... Such measures could be the change of the duty cycle to a range of 10-90% or the ramp down of the motor. Undervoltage shut down: The TLE6280GP has an integrated undervoltage shut-down, to guarantee that the behavior of the device is predictable in all voltage ranges. If the voltage of a bootstrap capacitor C Gate-Source voltage of the affected external Mosfet will be actively pulled to low ...

... Fig. 5: Block diagram of ERR functionality dI/dt control In all high current PWM applications, transient overvoltages and electro-magnetic emmisions are critical items. The dI/dt regulation of the TLE6280GP helps to reduce transient overvolt- age as well as electro-magnetic emissions. Each real bridge configuration has stray inductance in each half-bridge. When the Mosfets in the bridge are switching and load current is flowing, the stray inductance together with the dI/dt in the halfbridge causies transient overvoltages ...

... Not filling the bootstrap capacitors might lead to low Gate-Source voltages mainly in highside and can cause a short circuit de- tection when the highside switches are activated. Not changing the ILx input signal after enabling the device may cause the lowside outputs to stay in off conditions. Datasheet TLE6280GP ) * ...
