Feature

• 120 degrees square wave drive sensorless operation

• Motor speed is controlled by external PWM input signal

• Pre-driver for external Pch/Nch MOSFET (3 phase drive by 6 pre-driver output signal)

• Selectable lead angle setting

• Built-in 8bit ADC to detect over/under operating voltage

• Built-in 1ch comparator to detect EMF zero cross point for motor position detection

• Automated start duty control to maintain start up torque

• Abnormal detections (motor over-current, over voltage, under voltage, IC over temperature)

• Built-in internal 4 MHz OSC (at external R=39kΩ)

• Built-in 5V regulator with power on reset function

• Operating temperature：-40 to 125℃

• Small flat package SSOP-24pin (0.65 mm pitch)
