JUYI Tech JY03B 9-36V Wide Voltage Sensorless BLDC Motor Control IC
Highly Integrated Motor Driver Chip Simplified Motor Drive Design
JY03B - High-Integration Sensorless BLDC Motor Driver IC
Simplify Your Motor Design. Enhance Performance. Reduce Cost.
The JY03B is a highly integrated sensorless BLDC motor driver IC, designed to simplify motor control systems while delivering stable, efficient, and reliable performance. By integrating the core control circuit, MOSFET driver, and internal voltage regulators (12V & 5V LDO), the JY03B significantly reduces external component requirements—helping engineers accelerate development and lower overall system cost.

Key Features
  • High Integration Design - Built-in control logic, MOS driver, 12V & 5V LDO (excluding power MOSFETs)
  • Ultra-Simple Peripheral Circuit - Minimal external components required
  • Sensorless Control - No Hall sensors needed, simplifies system design and improves reliability
  • Advanced Protection Functions - Over-current, over-voltage/under-voltage, stall protection with auto-restart, thermal protection, and short-circuit protection
  • High Efficiency & Low Noise - Optimized PWM (16kHz) for better balance between efficiency and acoustic noise
  • Strong Startup Capability - Excellent load-start performance
  • Flexible Control - Analog speed control (VR input), direction control (ZF pin), startup torque adjustment (QD pin)
  • Wide Compatibility - Supports both Y (star) and Delta connected BLDC motors

Core Advantages
  • Fully Integrated Solution - Combines multiple critical functions into a single chip, reducing PCB size and BOM cost
  • Faster Development - Almost no complex tuning required—engineers can quickly complete system design
  • Reliable Performance - Integrated protection and optimized control ensure stable motor operation under various conditions
  • Hardware-Based Control - No MCU programming required, ideal for cost-sensitive and fast-deployment projects
