  • Description

    The A3934SLQ is a three-phase MOSFET controller designed for use with bipolar brushless DC motors. It enables the driving of all n-channel external power FETs, resulting in cost savings and minimizing power loss. This controller features a high-side drive block with bootstrap capacitors for floating positive supply and an intelligent FET monitoring circuit for proper gate voltage levels. It is suitable for applications with motor supplies ranging from 12 V to 28 V.
