LB11867FV-MPB-H Typical application Circuitry

LB11867FV-MPB-H

A three-phase brushless motor driver integrated circuit (IC) intended for compact cooling fans is the LB11867FV-MPB-H. It integrates a Hall sensor amplifier, motor control logic, and an output power stage in a single chip. This integration enables compact and efficient motor drive systems with simplified wiring and reduced component count.

Functionality: The LB11867FV-MPB-H controls the rotational speed of a three-phase brushless motor by varying the duty cycle of the PWM signals applied to the motor windings. It supports both lead angle control and speed control modes, allowing for optimized performance in different applications.

Applications: This chip is commonly used in cooling fans for electronic devices, such as computers, servers, and telecommunications equipment. Its compact size and efficient operation make it suitable for applications where space is limited and energy efficiency is important.

Parameters: Key parameters of the LB11867FV-MPB-H include its operating voltage range, output current capability, and PWM frequency range. It typically operates within a voltage range of 4.5V to 16V and can drive motors with currents up to 1A. The PWM frequency range is usually from a few kHz to tens of kHz, allowing for smooth motor control.

Circuit Design for a Cooling Fan Application:

1. Power Supply Connection: Connect a stable power source within the operating voltage range to the VCC pin (pin 1) of the LB11867FV-MPB-H. Ensure proper decoupling with a capacitor close to the VCC pin to filter out noise.

2. Motor Connections: Connect the three motor windings to the OUT1 (pin 8), OUT2 (pin 9), and OUT3 (pin 10) pins of the chip. These pins drive the motor phases.

3. Hall Sensor Inputs: Connect the outputs of the Hall sensors in the motor to the HA (pin 5), HB (pin 6), and HC (pin 7) pins. These inputs provide rotor position feedback for commutation.

4. PWM Speed Control: Attach a PWM signal to pin 3 (PWMIN) to adjust speed. The motor speed is determined by the duty cycle of this signal.

5. Lead Angle Adjustment: If lead angle control is required, connect a resistor to the LA pin (pin 2) to set the lead angle.

Design Considerations:

- Thermal Management: Ensure adequate heat dissipation for the LB11867FV-MPB-H, as it generates heat during operation. Use a heatsink if necessary.

- Motor Parameters: Choose a motor that is compatible with the output current and voltage specifications of the LB11867FV-MPB-H.

- EMI Suppression: Implement measures to suppress electromagnetic interference (EMI) generated by the motor and the driver IC, such as using snubber circuits and proper PCB layout techniques.

In summary, the LB11867FV-MPB-H is a versatile motor driver IC suitable for driving three-phase brushless motors in cooling fan applications. Its integration of control and power stages simplifies circuit design and reduces the overall system size. When designing a circuit with the LB11867FV-MPB-H, it is important to consider thermal management, motor compatibility, and EMI suppression to ensure reliable and efficient operation.
