5-channel high current driver
BA612
The BA612 is a high-current driver IC, and contains an array of five Darlington
transistors, each with input resistance. Input and output can be directed in the same direction using DIP Pin 14, with the layout optimized to facilitate mounting.
Applications Hammer solenoid drivers Relay drivers LED drivers
Features 1) 5-circuit Darlington
transistor array. 2) Large current (up to 400mA) can be driven. 3) Input and output pins are aligned in the same direction, for easy mounting.
4) High current transfer ratio. 5) Can be coupled with MOS ICs.
