MPQ1918GQE-AEC1-P

Overview

The MPQ1918GQE-AEC1-P is a high-frequency half-bridge GaN/MOSFET driver designed for automotive applications, holding AEC-Q100 Grade 1 certification. It operates with independent upper (HS) and lower (LS) PWM inputs and supports floating bias voltages up to 100V DC. The device features an internal bootstrap switch with voltage clamping to prevent gate overvoltage, ensuring safe operation for enhancement-mode GaN FETs and low-threshold N-channel MOSFETs. It provides adjustable turn-on and turn-off capabilities via independent gate outputs and utilizes a FCQFN-14 (3mm x 3mm) package with wettable flanks for reliable surface-mount installation.

Feature Summary

• Independent TTL logic inputs for upper and lower channels
• Internal bootstrap switching with voltage clamping protection
• Adjustable drive strength through independent gate outputs
• Wettable flank packaging for enhanced solder joint inspection

Applications

• Driving enhancement-mode Gallium Nitride (GaN) FETs in half-bridge configurations
• Driving low gate threshold voltage N-channel MOSFETs in synchronous applications
• High-frequency power conversion systems requiring precise timing control

Procurement Notes

Verify the specific suffix against official Monolithic Power Systems documentation to confirm package type and tape/reel specifications. Ensure the ordering part number matches the required AEC-Q100 Grade 1 qualification level. Cross-reference the datasheet for exact thermal and electrical ratings before finalizing procurement to avoid compatibility issues with target semiconductor devices.

Selection Notes

Select this component when driving wide-bandgap semiconductors or low-Vgs MOSFETs in high-voltage half-bridge topologies. The integrated voltage clamp is critical for protecting GaN devices from excessive gate-source voltage. Consider the FCQFN-14 footprint for space-constrained designs requiring robust soldering reliability through wettable flank technology.
