Description
The SA8833C is a bipolar stepper-motordriver with dual, built-in full-bridgesconsisting of N channel powerMOSFETs.
It operates from a supply voltage rangeof 2.7V to 15V and can deliver motorcurrent up to 1.0A per channel. Theinternal safety features includeovercurrent protection, short-circuitprotection, sinking and sourcing currentlimits implemented with externalsensors, under-voltage lockout andthermal shutdown. InternalAn over-temperature output flag isavailable to indicate thermal shutdown.
The SA8833C is available in5.0mm×6.4mm ETSSOP16L andQFN3X3-16 package.
