MCP8024-H/MP

Overview

The MCP8024-H/MP is a fully integrated three-phase brushless DC (BLDC) motor driver manufactured by Microchip Technology. It operates within a supply voltage range of 6V to 28V and utilizes a 40-QFN (5x5 mm) package with an exposed pad for thermal management. The device supports PWM interfaces and includes built-in control functions for commutation and direction management. Designed for robust performance, it features an operating temperature range from -40°C to +150°C. The component integrates pre-drivers configured as three half-bridges to drive external power MOSFETs, providing a compact solution for motor control applications.

Feature Summary

• Integrates control logic for commutation and direction management alongside pre-driver outputs for three half-bridge configurations.
• Supports PWM interface signals for precise speed and torque control of brushless DC motors.
• Engineered for high-temperature reliability with an extended junction temperature rating up to 150°C.
• Utilizes a compact 40-pin QFN package with an exposed thermal pad to facilitate efficient heat dissipation.

Applications

• Brushless DC (BLDC) motor control in industrial automation systems
• Fan and pump drives in HVAC equipment
