8-channel high current driver
BA6212
The BA6212 is a monolithic IC including 8 circuits and capable of high current drive. Capable of using a current as
high as 400mA, it has a strobe pin, and is thus ideal for use as a driver circuit in thermal printers. Its input can be
directly coupled to CMOS devices.
Applications
Thermal printers
Motors
Relays
LEDs and other drivers
Features
1) High current drive capability of 400mA (Max).
2) 8 circuits included.
3) Equipped with a strobe pin.
4) Easy installation due to inputs and outputs being
aligned in the same direction.
5) Input can be directly connected to CMOS devices.
