DMG4468LFG-VB Product details
Back to previous pageProduct introduction：
DMG4468LFG-VB is a Single N-MOSFET deeply optimized for low-voltage, high-current power switching scenarios. The Trench process combines ultra-low on-resistance with fast switching characteristics, and the DFN8(3X3) package achieves an excellent balance between thermal performance and board area. The combination of 30V withstand voltage, 30A current carrying capacity, and 13mΩ on-resistance makes it an ideal choice for high-density power conversion, battery protection, and motor drive applications, especially suitable for systems with strict requirements on power density and temperature rise.

VDS=30V: Suitable for 5V/12V/24V systems, providing sufficient voltage spike margin and reducing avalanche breakdown risk.
VGS=±20V: Compatible with a wide range of logic levels, can be directly connected to MCU/PMIC, simplifying drive circuit design.
Vth=1.7V (Typical): Can enter the fully enhanced region with low gate drive voltage, adapting to battery voltage decay and low-voltage startup scenarios.
RDS(on)=13mΩ @ VGS=10V: Ultra-low on-resistance, significantly reduces full-load conduction losses, improving system efficiency and reducing thermal burden.
ID=30A: Strong continuous current capability, confidently handling steady-state and transient current demands of high-power loads.
Package DFN8(3X3): Small size, low parasitic inductance, supports high-frequency switching, while optimizing PCB layout density and thermal conduction path.
Domain and module applications：
DC-DC Converters: Replaces traditional Schottky diodes in synchronous rectification applications; heavy-load efficiency is significantly improved, facilitating module miniaturization and high power density design.
Battery Protection Modules: 30A high current carrying capacity and microsecond-level switching response ensure fast shutdown during overcurrent/short circuit; low internal resistance reduces temperature rise of the protection board.
Low-Voltage Motor Drives: Low PWM switching losses, combined with low on-resistance, result in smoother motor operation and significantly lower controller heat generation.
Automotive Auxiliary Power Supplies: 30V voltage margin adapts to 12V automotive bus fluctuations; wide operating temperature range ensures reliability in harsh environments.
Portable Device Power Management: Small package and high efficiency aid ultra-thin design, extending battery life, suitable for high-density portable applications.
Power Tools and Industrial Controls: High current margin and robust thermal performance meet heavy-duty conditions, enhancing overall system robustness.
LED Lighting Drivers: Low conduction voltage drop reduces constant current source power consumption, supports multi-channel parallel connection, improving overall luminaire efficacy and reliability.
Selection Summary: The DMG4468LFG-VB perfectly combines 30A high current, 13mΩ ultra-low on-resistance, and a small DFN8(3X3) package within the 30V voltage platform. It is a high-performance, versatile choice for low-voltage, high-current switching applications, particularly suitable for projects with strict requirements on power density, efficiency, and thermal management.
