A3930 and A3931

Automotive 3-Phase BLDC Controller and MOSFET Driver

Features and Benefits

Description

▪ High current 3-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

TheA3930andA3931are3-phasebrushlessdc(BLDC)motor

controllers for use with N-channel external power MOSFETs.

They incorporate much of the circuitry required to design a

cost effective three-phase motor drive system, and have been

specifically designed for automotive applications.

A key automotive requirement is functionality over a wide

input supply range. A unique charge pump regulator provides

adequate (>10V) gate drive for battery voltages down to 7V,

and allows the device to operate with a reduced gate drive at

battery voltages down to 5.5V. Power dissipation in the charge

pumpisminimizedbyswitchingfromavoltagedoublingmode

at low supply voltage to a dropout mode at the nominal running

voltage of 14V.

▪ Provides +5 V Hall sensor power

▪ Low-current sleep mode

A bootstrap capacitor is used to provide the above-battery

supply voltage required for N-channel MOSFETs.An internal

charge pump for the high-side drive allows for dc (100% duty

cycle) operation.

Package: 48 Lead LQFP with exposed

thermal pad (suffix JP)

Internal fixed-frequency PWM current control circuitry can

be used to regulate the maximum load current. The peak

load current limit is set by the selection of an input reference

voltage and external sensing resistor. The PWM frequency is

set by a user-selected external RC timing network. For added

flexibility, the PWM input can be used to provide speed and
