DC Brushless Motor Driver IC PT-3016x Frequency Output Divide 1/1.5/2 Overview The PT3016x is a universal DC brushless motor driver IC. PT3016x is design for varies motor applications. PT3016x driver IC can use for signal coil DC and traditional double coil DC brushless motor. This driver IC accepts the hall IC input and drives the motor coil directly without any other describe transistor. Driver IC can drive the DC brushless motor to start operation at the lowest voltage of 1.5V, but this IC can operate for a wide voltage range from 2.0V up to 6.5V. PT3016x driver IC can support large current up to 400mA Applications Package: SOT-26 b1 1 GND 2 O1 3 HE E1 O2 SOT-26 e D 5 VDD 4 HIN C Hall IC FG A Input Devices A2 A1 Motor lock protection Built-in protection circuit for transient output Frequency Generation output Low power dissipation and high driving efficiency Ultra-low start voltage 6 X### : PT-3016 X = A---divide 1 X = B---divide 1.5 X = C---divide 2 ###---year, week code. b Features X### Single coils DC brushless motor.
