| Standard ICs 6-channel high current driver BA6256 The BA6256 is a low voltage, high current driver with six circuits, and is designed for applications such as LEDs, relays, solenoids, and other driver devices which operate at low voltages. This driver is particularly ideal for direct drive of CMOS controlled devices and other devices with a low input current of 5A (typ.). *Applications drivers Hammer solenoid Relay drivers LED drivers Features 1) Output current of 400mA (Max.) can be driven. 2) Equipped with strobe terminal. * 3) High input impedance. *Block diagram ST 1 16 VCC IN1 2 15 OUT1 IN2 3 14 OUT2 IN3 4 13 OUT3 IN4 5 12 OUT4 IN5 6 11 OUT5 IN6 7 10 OUT6 GND 8 Sub 9 N.C. *Absolute maximum ratings (Ta = 25C) Parameter Power supply voltage Power dissipation Input voltage Output current Operating temperature Storage temperature In this case, Tj = 15C.
