Microchip Technology Launches New Gate Driver IC for Three-Phase Brushless DC Motors
Microchip Unveils MCP8027: A Comprehensive 3-Phase Brushless Motor Gate Driver for Enhanced Efficiency and Control
BonChip Electronics, a trusted distributor of Microchip Technology's innovative motor control solutions, is excited to announce the release of the MCP8027. This advanced gate driver simplifies the design process for 3-phase brushless DC (BLDC) motors, empowering engineers to create high-performance and efficient motor control systems.
Integrated Solution for Streamlined BLDC Motor Driver Design
The MCP8027 integrates a comprehensive set of features, eliminating the need for multiple discrete components:
- Three Half-Bridge Drivers: Capable of delivering a peak output current of 0.5 A at 12 V, these drivers are specifically designed to control high-side and low-side NMOS MOSFET transistors for efficient motor operation.
- Shoot-Through, Over-Current, and Short-Circuit Protection: Built-in protection mechanisms safeguard the driver and connected components from potential electrical hazards.
- Power Module: The MCP8027 incorporates a buck converter with an output power of 750 mW, providing sufficient power to a companion microcontroller. Additionally, integrated 5 V and 12 V low dropout voltage regulators can deliver a current of 30 mA. This eliminates the need for external power supplies, simplifying system design. (The buck regulator can be deactivated if not required.)
- Operational Amplifiers (Op-Amps): Three operational amplifiers enable precise monitoring of motor current for effective control and feedback mechanisms.
- Comparator and Level Translators: These features enhance signal conditioning and compatibility within the driver circuit.
- Over-Temperature Sensor: Integrated thermal protection ensures safe operation by monitoring the device temperature and taking corrective actions if necessary.
Designed for Flexibility and Performance
The MCP8027 caters to diverse design requirements:
- Wide Operating Temperature Range: Functions reliably within a temperature range of -40°C to +150°C, suitable for various industrial environments.
- Package Options: Available in both 40-lead 5 x 5 QFN and 48-lead 7 x 7 TQFP packages, offering flexibility for space-constrained designs.
EV83F07A Evaluation Board: Simplifying BLDC Motor Driver Development
Microchip also offers the EV83F07A evaluation board, specifically designed to showcase the capabilities of the MCP8027:
- Cost-Effective and Adaptable: This two-layer board provides a cost-effective platform for evaluating the MCP8027's features and allows for customization to meet specific application needs.
- High Current Handling Capacity: The board is designed to handle larger currents, making it suitable for various motor control applications.
- Microcontroller and Algorithm Flexibility: Utilizes the dsPIC33CK128MP503 microcontroller, also from Microchip, and offers jumper configurability to enable exploration of different algorithms, such as sinusoidal single shunt FOC or trapezoidal motor control, in either sensor or sensorless modes.
