    JUYI JY02A Brushless Motor Driver IC 3-Phase Sensorless BLDC Controller, High Efficiency 5V SPWM Drive Chip for Smart Pumps, Cooling Fans, Air

    Overview

    The JY02A is a fully integrated sensorless BLDC motor driver IC, designed for simple application, high efficiency, and reliable protection. It eliminates the need for external comparators or programming, offering excellent adaptability for various BLDC motor systems.

    Typical applications: Robotic vacuums, automotive water pumps, circulation pumps, fans, compressors, power tools, automatic doors, AGV vehicles, and other BLDC-driven systems.

    Main Features

    • Operating Voltage: 4.5 V – 5.5 V
    • Drive Mode: SPWM, 13 kHz
    • Motor Type: Sensorless 3-phase BLDC motor
    • Speed Control: 0–5 V analog input
    • Rotation Direction: Forward / Reverse (Z/F control)
    • Soft Start & Smooth Reversal
    • Built-in BEMF Detection Circuit
    • Current, Voltage, Temperature, and Short-Circuit Protection
    • Adaptive Startup and Power Factor Correction
    • Automatic Restart after fault
    • Operating Temperature: –50 °C – 125 °C

    Functional Highlights

    • Over-Current & Constant Current Control: Maintains stable drive current when IS > 40 mV; protection triggered at ≥ 90 mV.
    • Blocked-Rotor Protection: Auto-restart up to 10 times; stops if restart fails.
    • Temperature Protection (TC Pin): Works with NTC 10K 3950; activates near 100 °C.
    • Soft Direction Change: Smooth transition between CW/CCW, protecting MOSFETs and motor.
    • Speed Signal Output (FG): Outputs one pulse per commutation for precise speed feedback.
    • Startup Torque Control: Adjustable via QD (0–2.5 V); typical range 0–0.8 V.

    Typical Application Circuits

    • Low Power: 7.5–28 V DC / 3 A / 30 W
    • Medium Power: 12–36 V DC / 16 A / 500 W
    • High Voltage: 80–265 VAC / 1 A / 150 W

    Package

    • Standard SSOP-20
    • Compact design, ideal for small-space applications

    Notes

    • JY02A is a second-generation sensorless BLDC controller integrating all key circuits for efficient and stable motor control.
    • Specifications are subject to change for performance improvement. Please confirm with the latest datasheet before design use.
