Full Half-Bridge (H Bridge) Drivers Procurement Notes

This component is officially classified as obsolete by the manufacturer and is no longer in production. Sourcing new units may be difficult or limited to surplus channels. Verify authenticity carefully when purchasing from third-party distributors. Ensure that any available stock matches the exact part number and package type. Consider immediate qualification of replacement parts to mitigate supply chain risks associated with end-of-life components.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this module only if legacy system compatibility is required and no direct functional equivalent is available. Evaluate thermal management requirements due to the 150°C junction temperature limit. Confirm that the 29-SIP footprint fits existing PCB layouts. Since it is obsolete, prioritize designs that allow for easy migration to newer IPM families with improved efficiency and availability.
