Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific manufacturer datasheet version when sourcing, as documentation dates vary between 1999 and 2006. Confirm that the SIP-9 package matches your PCB footprint requirements. Ensure the application voltage remains within the 4.5V to 15V limit to prevent damage. Check for RoHS compliance status if environmental regulations apply to your project.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component for simple reversible DC motor control requiring up to 700mA. The SIP-9 package suits through-hole designs where space is less constrained than surface mount options. Consider the limited operating temperature range if the environment exceeds 60°C. This driver is suitable for basic automation tasks rather than high-power industrial machinery.
