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
