2 General description  
The MLX90401 is a three-phase brushless DC  
motor controller, designed to meet the needs of  
high volume, low cost motors with 60o or 120°  
electrical sensor phasing which do not require  
the expensive options needed for servo or other  
closed loop applications.

The use of CMOS technology offers dense logic  
as well as high voltage (60V) driver capabilities.  
The use of discrete low cost N-channel power  
FETs reduces overall system cost and the  
device provides all of the logic necessary to  
interface Hall-effect position sensors to N-  
channel power FETs. Upper N-channel power  
FETs require a gate drive in excess of the  
supply voltage V+, and with the device’s on-chip  
“boost” voltage, the use of all N-Channel power  
FETs is allowed. Control inputs are provided for  
motor speed, forward or reverse direction,  
disable, and braking. 60° or 120° electrical  
sensor phasing can be set externally.
