PS8205A
20V Dual Channel NMOSFET
2. Applications
1. General Description
y Battery management in nomadic equipment
The PS8205A uses advanced trench technology
and design to provide excellent Rds(on) with low y DC motor control
gate charge. This device is suitable for use in high y DC-DC converters
efficiency switching applications, DC/DC y Power management in portable/desktop PCs
conversion, CPU power delivery and Synchronous
rectification. Standard Product PS8205A is Pb-free
(meets ROHS & Sony 259 specifications). It is
offered in the very popular TSSOP8 package 3. Features
y Vds=20V
y Id=6A (Vgs=8V)
y Rds(on)=<28mohm (Vgs=4.5V)
y Low capacitance minimizes driver loss
y Optimized gate charge minimizes switching
loss

Absolute Maximum Ratings
Stress greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. These stress ratings only, and functional operation of the device at these or any conditions beyond
those indicated under recommended Operating Conditions is not implied. Exposure to “Absolute Maximum
Rating” for extended periods may affect device reliability. Use of standard ESD handling precautions is
required..
