A3931, A3930 - Automotive 3-Phase BLDC Controller and MOSFET Driver

A3931 Description

A3930 and A3931 Automotive 3-Phase BLDC Controller and MOSFET Driver .
The A3930 and A3931 are three-phase brushless DC (BLDC) motor controllers for use with N-channel external power MOSFETs.

A3931 Features

* ▪ High current three-phase gate drive for N-channel MOSFETs ▪ Synchronous rectification ▪ Cross-conduction protection ▪ Charge pump and top-off charge pump for 100% PWM ▪ Integrated commutation decoder logic ▪ Operation over 5.5 to 50 V supply voltage range ▪ Extensive diagnostics output ▪ Provides

A3931 Applications

* A key automotive requirement is functionality over a wide input supply range. A unique charge pump regulator provides adequate (>10 V) gate drive for battery voltages down to 7 V, and allows the device to operate with a reduced gate drive at battery voltages down to 5.5 V. Power dissipation in the
