... L9341 FUNCTIONAL DESCRIPTION The U511 is a PWM quad low side driver for in- ductive loads. The duty cycle of the internal gen- erated PWM signal is set by a microcontroller via a serial interface for each output. An output slope limitation for both dv/dt and di /dt is implemented to reduce RFI. The PWM generation is realized avoiding a simultaneous output switching ...
