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.
