LB11867FV-TLM-E Typical application Circuitry

LB11867FV-TLM-E

The LB11867FV-TLM-E is a versatile chip designed for driving three-phase brushless DC motors, commonly found in cooling fans for electronic devices. It integrates a Hall sensor for rotor position sensing, enabling efficient and smooth motor operation.

Requests for Applications

Small cooling fans in laptops, servers, and other small electrical devices are a perfect fit for this chip. It can be used for small fans in consumer electronics and portable cooling solutions.

Key Parameters

- Supply voltage range: 2.5V to 12V

- Output current capability: Up to 1A

- Integrated Hall sensor for rotor position detection

- Power-saving mode for reduced energy consumption

- Soft switching feature for quieter operation

- Frequency generator (FG) output for speed feedback

Circuit Design for a Laptop Cooling Fan

1. Power Supply Connection: Attach the LB11867FV-TLM-E power source to the VCC (pin 4) and ground it at GND (pin 5) of the LB11867FV-TLM-E. Ensure the voltage is within the safe operating range.

2. Motor Coil Connections: Link the LB11867FV-TLM-E motor coils to OUT1 (pin 9), OUT2 (pin 10), and OUT3 (pin 11) for phase driving.

3. Hall Sensor Integration: Utilize the internal Hall sensor, eliminating the need for external connections.

4. Speed Regulation: Implement a PWM signal to the PWM (pin 7) for controlling the motor's speed through duty cycle adjustments.

5. Monitoring Motor Speed: Connect the FG (pin 6) to a monitoring system to track the fan's speed via the generated pulse signal.

6. Stabilization Capacitor: Place a bypass capacitor near the VCC and GND pins to ensure a stable power supply and mitigate noise.

Considerations for Circuit Design

- Adhere to the maximum voltage rating to avoid chip damage.

- Employ decoupling capacitors to minimize power supply fluctuations.

- Manage the chip's temperature to prevent performance degradation.

- Implement proper PCB layout practices to minimize EMI and ensure consistent operation.

Incorporating the LB11867FV-TLM-E into your design with these guidelines ensures efficient and reliable operation for three-phase brushless DC motors in compact cooling applications.
