MP86884DQKTE-LF-P

Full Half-Bridge (H Bridge) Drivers Overview

The MP86884DQKTE-LF-P is a monolithic half-bridge driver from Monolithic Power Systems, designed for high-current applications. It integrates high-side and low-side power MOSFETs with gate drivers to minimize parasitic inductance and optimize dead-time. The device supports a wide input voltage range of 4.5V to 14V and delivers up to 55A continuous output current per phase. Operating at switching frequencies between 100kHz and 1MHz, it accepts three-state PWM signals. Key features include Accu-Sense current sampling, temperature monitoring, overcurrent protection, and overtemperature protection (OTP). Packaged in a compact 6mm x 6mm TQFN.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix 'LF' indicates lead-free compliance and 'E' denotes tape-and-reel packaging configuration. Confirm that the component status aligns with design requirements, as related models may have different lifecycle statuses. Ensure compatibility with existing thermal management solutions given the high current density in the TQFN package.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component when a single-chip solution for high-current phases is required to save board space. It is suitable for designs needing integrated protection against overcurrent and overheating without external discrete components. Consider the 6mm x 6mm footprint constraints and the need for adequate PCB copper area for thermal dissipation during high-load operations.
