TECHNICAL NOTE

Motor Driver IC Series for Printers

DC Brush Motor Driver

for Paper Feed or Carriage Use

BA6920FP-Y, BA6219BFP-Y

●Description

The BA6920FP-Y and BA6219BFP-Y are full-on drivers for motors with DC brushes. They operate in forward rotation mode, reverse rotation

mode, stop (idling) mode, or brake mode, that are selectable according to the input logic (two inputs). The output voltage can be set through

the output voltage setting pin.

●Features

1) Large output current. (BA6219BFP-Y)

2) Built-in thermal shutdown circuit

3) The output voltage can be set flexibly through the output voltage setting pin.

4) Built-in standby (stop) circuit. (BA6920FP-Y)

●Applications

Devices that use DC brush motors, such as photo printers, scanners, mini printers, and fax machines.

●Absolute maximum ratings
