MPQ18913GRPE-AEC1-Z

Overview

The MPQ18913GRPE-AEC1-Z is a high-frequency half-bridge transformer driver designed for automotive applications and qualified to AEC-Q100 standards. It integrates control circuits, switching power stages, and protection mechanisms into a single device, serving as an ideal primary-side MOSFET driver for isolated bias supplies powering SiC FETs, silicon FETs, and IGBTs. The component supports a wide input voltage range of 5V to 30V with 50V surge tolerance and features a configurable switching frequency from 400kHz to 5MHz. It utilizes soft-switching technology to optimize EMI performance and includes comprehensive safety protections such as OVP, OCP, SCP, OTP, and UVLO.

Feature Summary

• Integrates control logic, switching power stage, and protection circuitry to simplify isolated bias supply design
• Supports wide input voltage range up to 30V with 50V surge capability for robust operation
• Configurable switching frequency range enables optimization of resonant topologies like LLC converters
• Advanced protection suite includes overcurrent, short-circuit, overvoltage, overtemperature, and undervoltage lockout

Applications

• Primary-side MOSFET driving in isolated power supplies for SiC FET biasing
• Gate driving for silicon FETs and IGBTs in automotive environments
• High-frequency transformer drivers utilizing LLC or similar resonant topologies
• Automotive electronic systems requiring AEC-Q100 qualified components

Procurement Notes

Verify the specific suffix 'Z' indicates tape-and-reel packaging when ordering. Confirm AEC-Q100 automotive qualification status matches project requirements. Ensure compatibility with the EVQ18913-D-01A evaluation board for initial testing. Check lead times as availability may vary due to automotive demand. Validate pinout and thermal pad specifications against PCB layout guidelines.

Selection Notes

Select this component for designs requiring integrated isolation barrier management without external gate drive ICs. The wide frequency range allows trade-offs between efficiency and passive component size. Consider the QFN-10 package dimensions for space-constrained layouts. Verify that the 30V input limit aligns with the system's maximum operating voltage and transient conditions.

Part Context

This part belongs to the MPQ18913 series of high-frequency transformer drivers from Monolithic Power Systems.
