30V Dual Channel PMOSFET

2. Applications
1. General Description
y PWM applications
The PS4953A uses advanced trench technology
and design to provide excellent Rds(on) with low y Load switch
gate charge and operation with gate voltages as y Power management
low as 2.5V. This device is suitable for use as a
load switch or in PWM applications. Standard
Product PS4953A is Pb-free (meets ROHS & Sony
259 specifications). It is offered in the very popular 3. Features
SOP8 package y Vds=-30V, Id=-6A
y Rds(on)=52mohm (Vgs=-10V)
y Rds(on)=67mohm (Vgs=-4.5V)
y High Power and current handing capability
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.
