Product Description

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
