Are you looking for a highly reliable, low-noise, and cost-effective solution for your brushless DC (BLDC) motors? The JY01 BLDC Motor Controller IC is engineered to meet your needs. Designed for both Hall sensor and sensorless motor applications, this versatile chip simplifies your peripheral circuit design while maximizing motor performance and lifespan.

Featuring the upgraded JY01 firmware, this IC integrates advanced JYKJ full-condition safety start technology, providing comprehensive overload, stall, and short-circuit protection for your drive system.

• Dual Drive Modes: Smoothly compatible with both Hall sensor motors and sensorless BLDC motors.

• Ultra-Low Noise (SPWM): Driven by Sinusoidal-like SPWM mode, it significantly restrains electromagnetic noise for whisper-quiet operation.

• Smart Protections: Equipped with active overload protection (0.1V threshold), motor shaft lock/stall protection (2.5s window), and instant short-circuit protection.

• Flexible Soft Start: Selectable soft-start periods (1S, 3S, and 10S options) to protect your motor and power supply from current spikes.

• Linear Speed Regulation: Supports wide range linear speed adjustments (0V - 5V).

The JY01 motor controller is widely adopted by electronic engineers globally for:

• Consumer & Home Appliances: Vacuum cleaners, air conditioning fans, high-end toys, air blowers.

• Automotive Parts: Electric windows, electric seat adjustments, auto fuel pumps.

• Smart Devices & Robotics: Balancers, electric scooters, robots, mower motors.

• Industrial & Handheld Tools: Grinding machines, hand drills, engraving machines, electric screwdrivers.

The JY01 is a dual-mode Brushless DC motor controller IC designed to drive both Hall sensor and sensorless BLDC motors. It integrates SPWM control, current regulation and multiple protection functions.

Yes. JY01 features a multi-functional Pin 1 (FO/EL). Connecting Pin 1 to VSS or 5V sets it to Hall sensor mode; offering 0.1V–4V to Pin 1 configures it for sensorless motor driving.

When the IS pin voltage reaches 0.1V, overload monitoring activates, limiting the current to maintain a stable drive state. If the IS pin voltage exceeds 0.2V due to an emergency, JY01 instantly shuts down all outputs within 4.5µs to prevent damage.

No. JY01 is a hardware-based motor controller IC and does not require firmware programming.
