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
