ML4420CS Product Details
The ML4420 motor controller provides complete commutation for delta or wye wound Brushless DC (BLDC) motors without the need for signals from Hall Effect Sensors to indicate rotor position. It senses the back EMF of the motor windings(no neutral required) to determine the proper comrmutation phase sequence using PLL techniques. The ML4420 uses a patented Back-EMF sensing technique which will commutate virtually any 3-phase BLDC motor and is insensitive to PWM noise and motor snubbing circuitry. The ML4420 controls the motor current with a constant off-time PWM or with a microprocessor controlled constant frequency PWM input. The velocity loop can becontrolled with an external microprocessor or through an analog feedback loop. An accurate, jitter-free, VCO output is provided, equal to the commutation frequency of the motor. The ML4420 modulates the gates of external N-channel power MOSFE Ts to regulate the motor current and directly drives the P-channel MOSFETs. The ML4420 supports enhancements like a blanker circuit to prevent false retriggering of the one shot during a motor current spike and circuitry to ensure that there is no shoot through in any state.
■Less than 200mW power dissipation
■Patented Back-EMF commutation technique provides jitterless torque for minimum"spin-up"time
■PWM motor current control
■Microprocessor based start-up algorithm allows for optimized start-up sequencing，speed control and support for variable motor loads
■Back-EMF comparator output senses motor rotationafter power fail for fast re-lock after brownout
■Onboard power fail detect monitor
■Onboard motor braking circuit allows life'braking on command层Drives external N-ch&P-ch FETS
■Enhanced version of the ML4410&ML4411
