Procurement Notes

Verify the specific suffix (VF) corresponds to the required tape-and-reel packaging configuration if automated assembly is planned. Confirm that the 32-SSOP footprint matches the target PCB design. Ensure the supply voltage limits align with the system's power rails to prevent damage to the internal MOSFET structures.

Selection Notes

Select this component when driving bipolar stepper motors with currents up to 1.5A are required. The wide load voltage range accommodates various motor specifications. Consider the 32-SSOP package size for space-constrained designs. Verify compatibility with the desired microstepping or drive mode requirements before finalizing the design.
