Document order number: MC33395/D Rev 2.0, 01/2004 MOTOROLA SEMICONDUCTOR TECHNICAL DATA Advance Information 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) 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.

Key Features

  • Drives Six N-Channel Low RDS(ON) Power MOSFETs.
  • Built-In Charge Pump Circuitry.
  • Built-In Current Sense Comparator and Output Drive Current Limiting.
  • Built-In PWM Mode Control Logic.
  • Built-In Circuit Protection.
  • Designed for Fractional to Integral HP BLDC Motors.
  • 32-Terminal SOIC Wide Body Surface Mount Package.
  • 33395 Incorporates a.
