Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix 'LG' corresponds to the eSIP-16K package variant when sourcing. Confirm RoHS3 compliance status as required by project specifications. Check for End-of-Life notices associated with the manufacturing date code. Ensure compatibility with through-hole assembly processes given the package type. Validate that the 11.4 V to 15 V supply range aligns with the target design constraints.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component for designs requiring high integration of LLC control and power switching. The eSIP-16K package facilitates thermal management via exposed pads. Consider the 600 mΩ on-resistance impact on conduction losses. Evaluate the need for automatic restart against system safety requirements. Verify that the 12.9 A peak current capability meets the transformer drive demands.
