... The maximum reference voltage accepted by the device depends from the supply voltage Vs (see 2. To reduce the switching losses the base bias of the bridge's low side NPN transistor is proportional to the DAC output, then the output current driving capability is also proportional to the DAC output voltage (see DAC=100 proportional for lower percentages) ...

... The monostable output is high during the pulse time, toff , which is determined by the time components R The single pulse switches off the power feed to the motor winding, causing the winding current to decrease during toff new trigger signal should occur during toff ignored. 3.5 Output stage The output stage contains four darlington transistors (source drivers) four saturated transistors (sink drivers) and eight diodes, connected in two H bridge ...

... Also, some stepper motors have such high core losses that they are not suited for switch mode current regulation. Unused inputs should be connected to proper voltage levels in order to get the highest noise immunity. As the circuit operates with switch mode current regulation, interference generation problems might arise in some applications ...
