AAT8543 Datasheet, PDF (1/6 Pages) Advanced Analogic Technologies – 20V P-Channel Power MOSFET

General Description
The AAT8543 is a low threshold P-channel MOSFET
designed for the battery, cell phone, and PDA mar-
kets. Using AnalogicTech's ultra-high-density MOS-
FET process and space-saving, small-outline, J-lead
package, performance superior to that normally
found in a TSOP-6 footprint has been squeezed into
the footprint of an SC70JW-8 package.
Applications
• Battery Packs
• Battery-Powered Portable Equipment
• Cellular and Cordless Telephones

1. Based on thermal dissipation from junction to ambient while mounted on a 1" x 1" PCB with optimized layout. A 5-second pulse on a
1" x 1" PCB approximates testing a device mounted on a large multi-layer PCB as in most applications. R_θJF + R_θFA = R_θJA where the
foot thermal reference is defined as the normal solder mounting surface of the device's leads. R_θJF is guaranteed by design; howev-
er, R_θCA is determined by the PCB design. Actual maximum continuous current is limited by the application's design.
2. Pulse test: Pulse Width = 300µs.
