The FDS6900AS_NL is a dual P-Channel PowerTrench® MOSFET from Fairchild Semiconductor (now ON Semiconductor). This device is designed for battery protection and load switching applications where space is a premium. It integrates two P-Channel MOSFETs in a single package for efficient power management.

Applications:

• Battery protection circuits
• Load switching
• Power management in portable devices
• DC-DC conversion
• Power distribution

Features:

• Dual P-Channel MOSFETs: Two MOSFETs in a single package for space saving.
• Low on-resistance (RDS(on)): Minimizes conduction losses, enhancing efficiency.
• Logic level gate drive: Enables direct drive from low voltage logic circuits.
• Fast switching speed: Reduces switching losses for high-frequency operations.
• Small footprint: TSSOP-8 package for compact designs.

Benefits:

• Space saving: Integration reduces the footprint on the PCB.
• Improved energy efficiency: Low RDS(on) minimizes power dissipation.
• Simplified design: Logic level gate drive simplifies interfacing with control circuits.
• Reduced component count: Decreases BOM complexity and simplifies assembly.

Additional Details:

The FDS6900AS_NL features a drain-source voltage (VDS) rating of -20V and a continuous drain current (ID) rating of -3.5A per channel. The RDS(on) is typically 0.065 Ohms at VGS = -4.5V. The TSSOP-8 package is designed for surface mount assembly. The gate threshold voltage (VGS(th)) is between -0.4V and -1V, suitable for logic-level control. Its characteristics make it perfect for applications where efficiency and size are critical factors.
