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 5
A (typ.).
1) Output current of 400mA (Max.) can be driven.
2) Equipped with strobe terminal.
3) High input impedance.
Applications
Hammer solenoid drivers
Relay drivers
LED drivers
