33395 Datasheet | Freescale Semiconductor

.. 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 bining 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 plementary PWM output signal to either low-side or high-side MOSFETs of the bridge. Detection and drive circuitry are also incorporated to control a reverse battery protection high-side MOSFET switch. PWM frequencies up to 28 k Hz are possible. Built-in protection circuitry prevents damage to the MOSFET bridge as well as the drive IC and includes overvoltage shutdown, overtemperature shutdown, overcurrent shutdown, and undervoltage shutdown. The device is parametrically specified over ambient temperature range of -40°C ≤ TA ≤ 125°C and 5.5 V ≤ VIGN ≤ 24 V supply.
