MPQ18913GRPE-A-AEC1-Z

Overview

The MPQ18913GRPE-A-AEC1-Z is a high-frequency half-bridge transformer driver designed for automotive applications, certified to AEC-Q100 standards. It operates with an input voltage range of 5V to 30V and withstands up to 50V surge voltages. The device integrates control circuits, a switching power stage, and protection mechanisms into a single component. It supports configurable switching frequencies between 400kHz and 5MHz. The unit is housed in a compact QFN-10 package measuring 2mm by 2.5mm with wettable flanks.

Feature Summary

• Integrates advanced safety protections including over-current, short-circuit, over-voltage, and over-temperature safeguards with fault reporting capabilities.
• Utilizes soft-switching technology to optimize electromagnetic interference performance while supporting wide input voltage ranges.
• Features a low-profile QFN-10 package with wettable side terminals to facilitate automated inspection and reliable surface-mount assembly.

Applications

• Primary-side MOSFET drivers for isolated bias power supplies
• Gate driving for silicon carbide (SiC) field-effect transistors
• Gate driving for insulated-gate bipolar transistors (IGBTs)

Procurement Notes

Verify the specific suffix codes on the ordering information to confirm the exact tape-and-reel packaging configuration and temperature grade. Ensure that the procurement documentation explicitly states AEC-Q100 qualification status for automotive compliance. Cross-reference the manufacturer part number against official Monolithic Power Systems databases to validate authenticity and current production status before finalizing orders.

Selection Notes

Select this component when designing isolated power architectures requiring high-frequency operation up to 5MHz to minimize passive component size. The integrated protection suite reduces external circuit complexity compared to discrete solutions. Consider the 2mm x 2.5mm footprint constraints and ensure thermal management strategies align with the device's power dissipation characteristics in dense automotive environments.
