Three-Phase Power MOSFET Controller

The A3938 is a three-phase, brushless DC Motor Controller It has a high-current Gate drive capability that allows driving of a wide range of Power MOSFETs and CAN support motor supply voltages to 50 V. The A3938 integrates a bootstrapped high-side driver to minimize the external component count required to drive N-Channel MOSFET drivers.
Internal fixed off-time, PWM current-control circuitry CAN be used to regulate the maximum load current to a desired value. The peak load current limit is set by the users selection of an input reference voltage and external sensing resistor. A userselected external RC Timing network sets the fixed off-time pulse duration. For added flexibility, the PWM input CAN provide speed/torque control where the internal current control circuit sets a limit on the maximum current.
