MP1921HQE-A-LF-Z

Overview

The MP1921HQE-A-LF-Z is a high-frequency half-bridge gate driver manufactured by Monolithic Power Systems. It operates within a supply voltage range of 9 V to 18 V and delivers a peak output current of 2.5 A. The device features non-inverting logic configuration with rise and fall times of 12 ns and 9 ns, respectively. Designed for surface-mount installation in a QFN-8 package, it supports operation at temperatures down to -40°C.

Feature Summary

High-speed switching capability with nanosecond propagation delays
Robust 100V blocking voltage rating for high-side applications
Compact surface-mount packaging suitable for dense layouts

Applications

Motor drive systems
Power supply circuits
Industrial control interfaces

Procurement Notes

Verify the specific suffix 'HQE' against official MPS documentation to confirm pinout and thermal pad configuration differences from standard variants. Ensure the selected component matches the required lead-free RoHS compliance status. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring fast switching speeds and moderate current drive capabilities for half-bridge topologies. Consider the 18V maximum supply limit and the specific QFN-8 thermal requirements. Evaluate the 2.5A output current against the target gate charge requirements of the connected power devices to ensure adequate drive strength without exceeding thermal limits.

Part Context

This part belongs to the MP1921 series of half-bridge drivers from Monolithic Power Systems. The series provides solutions for driving high-side and low-side power switches in various power conversion applications. The HQE variant specifically denotes the QFN-8 package type, distinguishing it from other package options like SOIC-8 available within the same functional family.
