NCV70624DW010R2G Typical application Circuitry

NCV70624DW010R2G

The NCV70624DW010R2G is an advanced motor driver integrated circuit (IC) designed for automotive applications, specifically targeting brushless DC (BLDC) motors used in applications like electric power steering, engine cooling fans, and HVAC blowers. This IC is known for its robust design, high efficiency, and integration of features that facilitate precise control and protection of the motor.

Application Scenarios:

In automobile systems that need BLDC motor control that is dependable and effective, the NCV70624DW010R2G is frequently utilized. Its applications include but are not limited to, power steering systems, HVAC systems for temperature control within the vehicle, and cooling fans that ensure the engine operates within the optimal temperature range.

Parameter Features:

Key features of the NCV70624DW010R2G include multiple control modes for BLDC motors, integrated power MOSFETs for driving the motor, a wide supply voltage range, built-in protection features such as overcurrent, overtemperature, and undervoltage lockout, and support for CAN communication for interfacing with other automotive systems.

Example Application Circuit - Electric Power Steering System:

- Supply Voltage Connection (Pin VBAT): Connect the VBAT pin to the vehicle's battery. This connection powers the integrated MOSFETs that drive the BLDC motor. A large capacitor should be placed close to this pin to filter any spikes or noise from the battery, ensuring stable operation.

- Ground Connection (Pin PGND): Secure a solid connection to the vehicle's ground. This is crucial for the operation of the NCV70624DW010R2G, ensuring that the return paths for the currents through the motor driver are low resistance.

- Motor Connection (Pins U, V, W): Connect these pins to the three phases of the BLDC motor. The NCV70624DW010R2G drives these phases in a sequential manner to rotate the motor. The sequence and timing are controlled internally by the IC based on the motor position feedback, which ensures efficient operation of the motor.

- Motor Position Feedback (Pins HALL1, HALL2, HALL3): Connect these pins to the Hall effect sensors of the BLDC motor. These sensors provide feedback on the motor's position, which is critical for commutating the motor accurately and efficiently.

- Control Interface (CANH, CANL): Utilize these pins to connect the NCV70624DW010R2G to the vehicle's CAN bus. This interface allows for control commands to be received from the vehicle's electronic control unit (ECU) and for status information to be sent back to the ECU, enabling sophisticated control strategies and diagnostics.

Design Considerations:

A circuit designed for the NCV70624DW010R2G needs to take into account a number of factors:

- Thermal Management: The IC and the motor it drives can generate significant heat. It is essential to implement sufficient cooling, such as ventilation or heatsinks, to avoid overheating and guarantee dependable performance.

- Power Supply Filtering: Given the harsh electrical environment in vehicles, incorporating robust filtering on the power supply lines is essential to protect the IC from voltage spikes and noise.

- Protection Features Utilization: Make full use of the built-in protection features. Design the circuit to ensure that conditions triggering these protections (like overcurrent or overtemperature) are avoided under normal operation but can act swiftly when needed to prevent damage.

- PCB Layout: Pay careful attention to the PCB layout, especially the paths carrying high currents to and from the motor and the power supply. In order to reduce resistance and inductance, these pathways should be wide and brief.

- CAN Interface Integrity: Ensure the integrity of the CAN communication lines with appropriate termination resistors and by keeping the differential pairs matched in length to facilitate reliable communication with the vehicle's ECU.

Incorporating the NCV70624DW010R2G into an electric power steering system demands careful attention to these design considerations, enabling the development of a system that offers reliable, efficient, and safe operation. The IC's advanced features and integrated protections make it a compelling choice for automotive BLDC motor control applications.
