JY01 Brushless DC Motor Controller IC for Hall & Sensorless BLDC Motors | SPWM Motor Driver Chip with Soft Start, Constant Current, Overload Protection & Speed Control

The JY01 is a professional Brushless DC (BLDC) Motor Controller IC designed for both Hall sensor and sensorless BLDC motors. Featuring SPWM sinusoidal drive, soft start, overload protection, constant current control, stall protection and speed feedback output, it provides a reliable, low-noise and highly efficient motor control solution for industrial and consumer electronics.

The JY01 Brushless DC Motor Controller IC is a highly integrated BLDC motor control solution developed by JUYI Tech for compact, reliable and cost-effective motor driver designs.

Unlike conventional controller ICs that only support one motor type, JY01 integrates both Hall sensor and sensorless control modes in a single chip, allowing engineers to simplify PCB design while reducing BOM cost.

Designed with advanced SPWM (Sinusoidal PWM) control technology, the JY01 delivers smoother motor operation, reduced acoustic noise and improved electromagnetic compatibility (EMC).

Its built-in safety functions—including overload protection, constant current control, rotor lock protection and soft start—help improve overall system reliability while protecting both the motor and power electronics.

The JY01 is suitable for a wide range of BLDC motor applications, from miniature embedded motor drivers to industrial motor control systems.

Supports both Hall Sensor BLDC Motors and Sensorless BLDC Motors with one controller IC.

Generates near-sinusoidal SPWM waveforms for:

• Lower motor noise
• Reduced vibration
• Improved efficiency
• Better EMC performance

Selectable soft-start periods:
