Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify product status carefully as this component is marked Not Recommended for New Designs (NRND). Confirm availability through authorized distributors, noting that stock may be limited or restricted. Ensure compliance with RoHS requirements before procurement. Check for specific shipping restrictions applicable to your region. Validate that the FC-TQFN(4x6) package fits your PCB layout constraints.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this driver when a robust half-bridge solution with 40A output capability is required. It is suitable for designs needing integrated fault protection against overcurrent and thermal events. Consider the 29-FC-TQFN(4x6) package size for space-constrained layouts. Verify that the 14V maximum load voltage aligns with the external MOSFET gate drive requirements. Ensure the control logic operates within the specified 4.5V to 5.5V supply range.

Full Half-Bridge (H Bridge) Drivers Part Context

This part belongs to the MP86885 series of specialized PMIC components from Monolithic Power Systems. It functions as a dedicated gate driver rather than a complete switching regulator. The device complements other MPS power management solutions by providing the necessary drive signals for external power switches in efficient power conversion topologies.
