The AMT49413K 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, and has been  
specifically designed for automotive applications.  
AMT49413K  
Automotive 3-Phase BLDC Controller and MOSFET Driver  
FEATURES AND BENEFITS  
DESCRIPTION  
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  
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  
and wettable flank (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
