FDG6331L
Integrated Load Switch
General Description
Features
This device is particularly suited for compact power
management in portable electronic equipment where
2.5V to 8V input and 0.8A output current capability are
needed. This load switch integrates a small N-Channel
power MOSFET (Q1) that drives a large P-Channel
power MOSFET (Q2) in one tiny SC70-6 package.
• –0.8 A, –8 V.
RDS(ON) = 260 mΩ @ VGS = –4.5 V
RDS(ON) = 330 mΩ @ VGS = –2.5 V
RDS(ON) = 450 mΩ @ VGS = –1.8 V
• Control MOSFET (Q1) includes Zener protection for
ESD ruggedness (>6KV Human body model)
Applications
• High performance trench technology for extremely
low RDS(ON)
• Power management
• Load switch
• Compact industry standard SC70-6 surface mount

Notes:
1. RθJA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting surface of
the drain pins. RθJC is guaranteed by design while RθJA is determined by the user’s board design.
2. Pulse Test: Pulse Width < 300µs, Duty Cycle < 2.0%.

FAIRCHILD’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE
EXPRESS WRITTEN APPROVAL OF FAIRCHILD SEMICONDUCTOR CORPORATION.
As used here in:
1. Life support devices or systems are devices or systems which, (a) are
intended for surgical implant into the body or (b) support or sustain life,
and (c) whose failure to perform when properly used in accordance with
instructions for use provided in the labeling, can be reasonably
expected to result in a significant injury of the user.

ANTI-COUNTERFEITING POLICY
Fairchild Semiconductor Corporation’s Anti-Counterfeiting Policy. Fairchild’s Anti-Counterfeiting Policy is also stated on our external website,
www.Fairchildsemi.com, under Sales Support.
Counterfeiting of semiconductor parts is a growing problem in the industry. All manufactures of semiconductor products are experiencing counterfeiting of their
parts. Customers who inadvertently purchase counterfeit parts experience many problems such as loss of brand reputation, substandard performance, failed
application, and increased cost of production and manufacturing delays. Fairchild is taking strong measures to protect ourselves and our customers from the
proliferation of counterfeit parts. Fairchild strongly encourages customers to purchase Fairchild parts either directly from Fairchild or from Authorized Fairchild
Distributors who are listed by country on our web page cited above. Products customers buy either from Fairchild directly or from Authorized Fairchild
Distributors are genuine parts, have full traceability, meet Fairchild’s quality standards for handing and storage and provide access to Fairchild’s full range of
up-to-date technical and product information. Fairchild and our Authorized Distributors will stand behind all warranties and will appropriately address and
warranty issues that may arise. Fairchild will not provide any warranty coverage or other assistance for parts bought from Unauthorized Sources. Fairchild is
committed to combat this global problem and encourage our customers to do their part in stopping this practice by buying direct or from authorized distributors.
