Description
Revolution Pulse Output. Pulses per revolution=motor poles ÷ 2 × 3.
Digital Ground
Voltage Regulator Output. A 0.1µF (minimum) capacitor should be connected between this
pin and ground.
Positive Input of Torque Error Amplifier
Output of Torque Error Amplifier
Negative Input of Torque Error Amplifier
Current Feedback Output
PWM Duty Control Input. Designed to directly control the PWM duty cycle in stand-alone
operation.
External Resistor of Clock Generator. Designed for determining the frequency of the
internal clock generator.
Analog Ground
Current Feedback Input
Angle Shift Input. Designed for correcting the lead angle of PWM output signals. The range
is from 0° to 60° related to the induced magnetic voltage.
Motor Drive Voltage-Sensing Resistor. Designed for determining the voltage level of over-
voltage protections.
Thermistor Voltage Input. Connect to a NTC (Negative Temperature Coefficient)
thermistor for the over-temperature protection.
Overload Time-Out Programmable Input. Connect to a capacitor for determining the time
delay of overload protection.
Fault Flag. Open-drain output, LOW: system failure.
