MP8040DN-LF-Z

Full Half-Bridge (H Bridge) Drivers Overview

The MP8040DN-LF-Z is a high-frequency, general-purpose half-bridge power driver from Monolithic Power Systems. It integrates upper and lower N-channel MOSFET power switches with a maximum drive capability of 9A peak current. The device operates within a wide input voltage range of 7.5V to 25V and supports switching frequencies up to 1.2MHz. Key electrical characteristics include ±9A peak output current, ±4.25A continuous output current, and a standby current of 2.5µA. It features protected 100mΩ internal power switches with cycle-by-cycle current limiting for both sourcing and sinking currents.
