Description
The ML4411ACS is an electronic component model in the IC Chips product category. It is designed to provide complete commutation for delta or wye wound Brushless DC (BLDC) motors without the need for signals from Hall Effect Sensors. This IC senses the back EMF of the three motor windings to determine the proper commutation phase angle using Phase Lock Loop techniques. It is capable of commutating virtually any 3-phase BLDC motor and is not affected by PWM noise or motor snubbing. The ML4411ACS has improved braking and brown-out recovery circuitry compared to the ML4410.
Specifications and features
- Back-EMF commutation provides maximum torque for minimum "spin-up" time for spindle motors
- Accurate, jitter-free phase locked motor speed feedback output
- Linear or PWM motor current control
- Easy microcontroller interface for optimized start-up sequencing and speed control
- Power fail detect circuit with delayed braking
- Drives external N-channel FETs and P-channel FETs
- Back-EMF comparator detects motor rotation after power fail for fast re-lock after brownout
Application Scenarios
The ML4411ACS can be used in various applications that require commutation control for delta or wye wound BLDC motors. It is particularly suitable for applications where signals from Hall Effect Sensors are not available or reliable. Some application scenarios include:
- Electric vehicles
- Robotics
- Industrial automation
- HVAC systems
Comparison
Advantages- Provides complete commutation without the need for signals from Hall Effect Sensors
