www.DataSheet4U.com Freescale Semiconductor Document Number: MC33395 Technical Data Rev 4.0, 2/2007 Three-Phase Gate Driver IC The 33395 simplifies the design of high-power BLDC motor control design by combining the gate drive, charge pump, current sense, and protection circuitry necessary to drive a three-phase bridge configuration of six N-channel power MOSFETs. Mode logic is incorporated to route a pulse width modulation (PWM) or a complementary PWM output signal to either low-side or hig.
