48V BLDC Motor Position Control

BLDC motor applications have been increasing rapidly due to the demand for smaller, high-efficiency products. The core of a BLDC motor design is a robust and reliable motor control circuit paired with a versatile MCU for a safe control algorithm. Key components of a motor control circuit include a MOSFET driver, versatile MCU, voltage regulators, cell balancer, and battery charger. This 48V position control system integrates these components to deliver precise and efficient motor control for various industrial applications.

System Benefits:

• Utilizes an ultra-low power MCU for energy efficiency.
• Offers a fast wake-up time of 4µs for responsive control.
• Features an integrated 12-bit ADC with an op amp and comparator.
• Provides accurate cell balancing and monitoring with customer-programmable EEPROM for customization.
