Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality.
Provide a 5-V supply to VCC1 and valid logic input levels to data and enable inputs. VCC2 must be connected to a power supply capable of suppling the needed current and voltage demand for the loads connected to the outputs.
The design techniques in the following sections may be used for applications which fall within the following requirements.
Driver output voltage waveform with a two phase stepper motor; 12-V 20-Ω coils.
