FDMA905P-VB Product details
Back to previous pageProduct introduction：
The FDMA905P-VB is a Single P-MOSFET deeply optimized for low-voltage power switching scenarios. The Trench process balances low switching losses with high reliability, and the DFN6(2X2) package achieves an excellent balance between heat dissipation and board area. The combination of -20V voltage tolerance, -10A current capability, and 20mΩ on-resistance (@VGS=10V) makes it an ideal high-density alternative to traditional SOT-23 or SOP-8 packaged devices, especially suitable for compact applications like portable devices and battery protection.

VDS=-20V: Suitable for 3.7V/7.4V/12V systems, providing ample margin for battery voltage fluctuations and load spikes, reducing breakdown risk.
VGS=±20V: Compatible with a wide range of logic level drives, can be directly connected to MCU/PMIC, simplifying peripheral drive circuit design.
Vth=-0.6V (Typical): Low threshold voltage, suitable for low-voltage domain drive, can still be fully turned on even when battery voltage decays.
RDS(on)=20mΩ @ VGS=10V: Ultra-low on-resistance, significantly reduces full-load power consumption, minimizes heat generation, improves system efficiency; also provides 40mΩ (VGS=2.5V) and 28mΩ (VGS=4.5V) options to suit different drive voltages.
ID=-10A: Ample continuous current margin, can handle peak demands of most portable and load switch applications.
Package DFN6(2X2): Ultra-small size, low parasitic parameters, supports high-frequency switching, significantly saves PCB area and assembly costs.
Domain and module applications：
Portable Device Power Management: Low internal resistance improves boost/buck efficiency, extends battery life; DFN6 small package aids ultra-thin design.
Battery Protection Modules: Fast response ensures microsecond-level shutdown during overcurrent/short circuit; low internal resistance reduces self-heating of the protection board.
Load Switch: Suitable for power rail on/off control; low threshold voltage allows direct drive by 1.8V/2.5V logic, simplifying control circuits.
Low-Voltage Motor Drive: Low PWM switching losses, smoother motor operation, significantly lower driver temperature rise.
Consumer Electronics Control Modules: Compatible with multi-level logic drive, suitable for high-volume, low-cost products like smart wearables and USB switches.
LED Lighting Driver: Low conduction voltage drop reduces constant current source power loss, supports multi-channel parallel connection, improves overall luminaire efficacy.
DC-DC Converters: Replaces standard P-Channel devices in synchronous rectification, offering significant light-load efficiency advantages, beneficial for module miniaturization.
Selection Summary: The FDMA905P-VB achieves a balance between performance margin, package size, and system cost. It is a cost-effective general-purpose choice for -20V low-voltage P-Channel switching applications, particularly suitable for projects with strict requirements on space, power consumption, and heat dissipation.
