Procurement Notes

Verify the exact part number suffix against official Toshiba documentation to ensure correct packaging and tape specifications. Confirm that the required operating temperature range aligns with the specified -20°C to 85°C ambient rating. Ensure PCB layout accommodates the thermal requirements of the WQFN package. Cross-reference the latest datasheet revision for any updates to electrical characteristics or recommended operating conditions prior to final procurement.

Selection Notes

Select this component when a fully integrated solution for bipolar stepper motors is required without external power transistors. It is suitable for applications needing 2A continuous output current within a 35V load voltage limit. Consider the 36-WQFN package size for space-constrained designs. Verify compatibility with the system's logic supply voltage range of 2V to 5.5V. This driver is appropriate where PWM control signals are available for step resolution management.
