6-channel high current driver

BA664

The BA664 is an IC with a built-in clamp diode, developed for the purpose of minimizing attachments, and contains a

Darlington transistor array of six circuits with input resistance. Input and output are directed in the same direction by

DIP Pin 14, with the layout optimized to facilitate mounting.

Applications drivers

Hammer solenoid

Relay drivers

LED drivers

Small motor drivers

Lamp drivers

•

Features Darlington transistor array

1) 6-circuit

2) Current of 100mA (Max.) can be driven.

3) Input and output are directed in the same direction,

for easy mounting.

4) Can be coupled with MOS ICs.

5) High current transfer ratio.

6) High voltage withstanding values of 38V for input

and 27V for output.

7) Clamp diode for inductive load drive built in.
