HA13408
9-Channel Power Driver
ADE-207-206 (Z)
1st Edition
July 1996
Description
The HA13408 9-channel power driver IC is designed to drive dot matrix printer head. This IC can drive 9
pins without using any external components. HA13408 can be used for 2 system four-phase step drive, as
every channel is used independently.
Features
High output current: 1.5 A/channel Max
High sustaining voltage: 50 V Min
Low saturation voltage
Low supply current
Low input current
Compatible with TTL, LSTTL & 5 V CMOS
Low thermal resistance package
Zener diodes
