HA13408
HA13408 is 9-Channel Power Driver manufactured by Hitachi Semiconductor.
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 ponents. HA13408 can be used for 2 system four-phase step drive, as every channel is used independently.
