BA6950FS_10 Datasheet, PDF (1/10 Pages) Rohm – Reversible Motor Drivers for 0.8A or less (1 Motor)

Reversible Motor drive IC Series for Brush Motors
Reversible Motor Drivers
for 0.8A or less (1 Motor)
BA6950FS, BA6951FS
No.10008EBT01
 Overview
These drivers are reversible motor drivers that can directly drive brush motor which require forward and reverse rotations.
Four modes of output setting are available by the use of input logic (2 inputs); forward, reverse, stop (idling), and braking. In
addition, since voltage applied to motors varies in accord with the control terminal, motor rotating speed can be optionally
set and by the built-in current feedback amplifier, the motor can be driven at a constant speed.
 Features
1) Four-mode outputs of forward, reverse, stop (idling), and braking are enabled in compliance with two inputs
2) Motors can be driven at a constant speed by a current feedback amplifier
3) Built-in thermal shutdown circuit
4) Built-in current limiting function (BA6951FS)
 Applications
Audio-visual equipment; PC peripherals; Car audios; Car navigation systems; OA equipments
 Absolute maximum ratings (Ta=25°C, All voltages are with respect to ground)
