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)
signal to either the low-side MOSFETs or high-side MOSFETs of the bridge, or
to provide complementary PWM outputs to both the low- and high-sides 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 an ambient temperature range of
-40°C ≤ T_A ≤ 125°C and 5.5 V ≤ V_IGN ≤ 24 V supply.
