MP1921HS-A-LF-Z

Overview

The MP1921HS-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 a rise time of 12 ns and a fall time of 9 ns, with a maximum propagation delay of 16 ns. It is housed in an SOIC-8 surface-mount package and supports non-inverting configurations. The component is rated for operation between -40 °C and +125 °C.

Feature Summary

High-speed switching capability with nanosecond-level rise and fall times for efficient power stage control
Robust half-bridge topology supporting dual independent outputs for complete bridge driving applications
Wide operating temperature range suitable for demanding industrial and automotive environments

Applications

Motor drive systems requiring precise gate signal generation
Industrial power conversion circuits utilizing half-bridge topologies
Automotive electronics applications needing reliable high-frequency switching

Procurement Notes

Verify the specific suffix 'A' against official MPS documentation to confirm pinout and electrical characteristics match your design requirements. Confirm RoHS compliance status through authorized distributors. Check for obsolescence notices as this part may have limited availability compared to newer revisions. Ensure ESD handling protocols are followed during storage and assembly.

Selection Notes

Select this component when a dedicated half-bridge driver with moderate output current is required. Compare performance metrics such as propagation delay and output current against alternative drivers in the same series. Consider package constraints and thermal management needs for the SOIC-8 footprint. Evaluate compatibility with input logic levels and supply voltage ranges of the target application.

Part Context

This device belongs to the MP1921 series of high-frequency gate drivers from Monolithic Power Systems. It complements other variants like the MP1921HQ which utilizes a QFN-8 package. The series focuses on providing reliable switching signals for power MOSFETs and IGBTs in compact form factors suitable for space-constrained designs.
