Technical Data
Three-Phase Gate Driver IC
33395
33395T
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.
THREE-PHASE
GATE DRIVER IC
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.
