Description

The 3535 step motor driver is a full or half drive,

step phase sequencer with MOSFET three state

switching amplifiers and optoisolated circuits. The

drive also includes an automatic feature to lower

motor current by 50 anytime the motor is left at

rest for more than one second.

The amplifier regulates motor current by chopping

at a constant, inaudible frequency. Phase current is

selected from 32 levels by a DIP switch. Full or half

resolution is DIP switch selected.
