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 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 kHz 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
