Table 3: MLX90401 electrical specifications  
7 General description  
7.1 Overview  
The MLX90401 contains all functions for controlling three-phase brushless DC motors in open loop  
applications.  
The MLX90401 supports following control functions:  
speed control  
forward or reverse rotation  
braking  
disable  
The chip contains:  
a rotor position decoder for proper commutation sequencing  
a voltage reference that supplies power for the sensors  
a pulse width modulator (PWM) based on a frequency programmable sawtooth oscillator  
three top and three bottom drivers  
Using a bootstrap/charge pump combination, the MLX90401 also generates a boost voltage to drive the top  
power FET. In this way the application only uses N-channel power FETS, to reduce overall system cost.  
The MLX90401 provides commutation from Hall-effect sensors, and can be configured for motors with 60°  
or 120° sensor electrical phasing, by means of a select pin.  
Undervoltage lockout is provided.
