For brush motors

Reversible motor drivers

(up to 2A series)

BA6219BFP-Y, BA6222



Overview

These motor drivers are full bridge drivers for brush motor applications, supporting output currents of up to 2A. The output

modes are available in four modes, normal, reverse, stop (idling), and braking in accordance with input logic (2 inputs). The

output voltage can be optionally set by reference voltage setting pin.



Features

2) Built-in thermal shutdown circuit

3) Output voltage can be optionally set by reference voltage setting pin

4) High output voltage can be set by low voltage input because of it has 11.4dB gain (BA6222)

5) Low standby current



Applications

Audio-visual equipment; PC peripherals; Car audios; Car navigation systems; OA equipments
