3-Phase BLDC Controller and MOSFET Driver

FEATURES AND BENEFITS

DESCRIPTION

The AMT49413 is a 3-phase brushless DC (BLDC) motor

controller for use with N-channel external power MOSFETs.

It incorporates much of the circuitry required to design a cost-

effective three-phase motor drive system.

TheAMT49413providesfunctionalityoverawideinputsupply

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 pump

is minimized by switching from a voltage doubling mode at

low supply voltage to a dropout mode at the nominal running

voltage of 14V.

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 QFN with exposed thermal pad

(suffix EV)

Internal fixed-frequency PWM current control circuitry can

be used to regulate the maximum load current. The peak load

currentlimitissetbytheselectionofaninputreferencevoltage

and external sensing resistor. The PWM frequency is set by a
