BA6209中文资料Reversible motor driver数据手册ROHM规格书

描述 Description

Reversible motor driverThe BA6209 and BA6209N are reversible-motor drivers suitable for brush motors. Two logic inputs allow three output modes : forward, reverse, and braking. The motor revolving speed can be set arbitrarily by controlling the voltage applied to the motor with the control pin voltage VR.\u0001

特性 Features

1) Power transistors can handle a large current (1.6A maximally).
2) Brake is applied when stopping the motor.
3) Built-in function to absorb rush currents generated by reversing and braking.
4) Motor speed controlling pin.
5) Small standby current.
   (VCC= 12V, IO= 5.5mA typically)
6) Stable operation during mode changes either from forward to reverse or vice versa.
7) Interface with CMOS devices.

\u0001Applications
VCRs and cassette tape recorders
