... Adjustable slew rates for optimized EMI 2 Brief functional Description The FAN7093_F085 is an integrated high current half bridge for electric motor drive applications. It contains one P-channel high- side MOSFET and one N-channel low-side MOSFET with an integrated control IC in one package. With the P-channel high- side switch the need for a charge pump is eliminated and therefore minimizing EMI ...

... MOSFETS also against over voltage, under voltage and over temperature. The dead time to prevent shoot through between P- and N- channel MOSFET is generated by the control IC too. The slew rate of the outputs can be adjusted through an external resistor connected to the SR pin. The FAN7093_F085 can be combined with other FAN7093_F085 to form Full-bridge and also 3-phase drive configurations. ...

... Quiescent Current 7 Power Stages The power stages of the FAN7093_F085 consist of a p-channel vertical DMOS transistor for the high side switch and a n-channel vertical DMOS transistor for the low side switch. All protection and diagnostic functions are located in the control die. Both switches can be operated kHz, allowing active freewheeling and thus minimizing power dissipation in the forward operation of the FAN7093_F085 Rev ...

... Repetitive use of the over temperature protection impacts lifetime. 7.2.4 Current Limitation The current is measured in both MOSFETS of the FAN7093_F085. As soon as the current is reaching the limit I , the low- or high-side MOSFET is deactivated and the other MOSFET activated for t CL During that time changes at the IN pin are ignored ...

... In combination with a typical inductive load, such as a motor, this results in a switched mode current limitation. This method of limiting the current has the advantage of greatly reduced power dissipation in the FAN7093_F085 compared to driving the MOSFET in linear mode. Therefore it is possible to use the current limitation for a short time without exceeding the maximum allowed junction temperature (e ...
