drive applications. Integrated desaturation logic pro-

vides ground fault protection as well as other mode of

over current protection. Soft shutdown is initiated in

the event of any overcurrent/ground fault conditions,

and all six outputs are simultaneously turned off. Out-

put drivers have separate turn on/off pins to facilitate

independent gate drive impedance with EMI soft turn

on. Optimum matched delays between phases, and

between high/low side enables small deadtime, thus

improving low speed performance. The brake driver

eliminates additional circuits.
