Reduce static and switching power loss

Worcester, Massachusetts,- 亚博棋牌游戏Allegro MicroSystems announced new IC dual full bridge PWM motor, with office automation, automotive, industrial and consumer markets as the goal.The AllegroA4970 motor ICAdopt the DMOS output technology, can also drive a bipolar stepper motor of two winding or two-way control dc motor.Can withstand voltage of 45 V two bridge, including 750 mA output current internal pulse width modulation (PWM) control.

For PWM current control, maximum output current depends on the user's choice of the reference voltage and induced resistance.Two logic level input can choose the output current limit for the maximum level of 0%, 33%, 67% or 100%.Each bridge "phase" input determines the direction of load current.

The device packaging is 24 pin surface installation wide-body SOIC, with two pairs of bat type pin (LB).Pin the weaving structure enables device with a minimum of space to achieve maximum heat dissipation effect.Fog the encapsulated as lead-free packaging, with 100% of tin plating pin frame.
