By unifying the gate drive, charge pump, current sensor, and protection circuitry required to drive a three-phase bridge arrangement of six N-channel power MOSFETs, the 3 phase MOSFET Driver simplifies the design of high-power BLDC motor control.
The Global 3-Phase MOSFET Driver market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
By combining the gate drive, charge pump, current sensor, and protection circuitry required to operate a three-phase bridge arrangement of six N-channel power MOSFETs, the 33395 streamlines the design of high-power BLDC motor control.
To direct a pulse width modulation (PWM) or complementary PWM output signal to the bridge’s low-side or high-side MOSFETs, mode logic is used.
A reverse battery protection high-side MOSFET switch is similarly managed by detection and driving circuitry. Up to 28 kHz in PWM frequency range is feasible.
Built-in protective circuitry, which includes overvoltage shutdown, over temperature shutdown, overcurrent shutdown, and undervoltage shutdown, guards against damage to the MOSFET bridge and the drive IC.
Allegro Microsystems’ A4915 is a three-phase MOSFET driver that can drive the gates of six N-channel power MOSFETs at high currents.
Gate drive down to 7 V supply is guaranteed by an internal charge pump, and restricted gate drive down to 5 V is provided.
By avoiding complex software development, the gadget reduces time to market and lowers system costs for users.
For N-channel MOSFETs, a supply voltage that is higher than the source voltage of the high side MOSFET is produced using a bootstrap capacitor.
