| 20V P-Channel Power MOSFET General Description The AAT8308 is a low threshold P Channel MOSFET designed for the battery, cell phone, and PDA markets. Using AnalogicTechTM's proprietary ultrahigh density Trench technology, and space saving small outline J-lead package, performance superior to that normally found in a larger footprint has been squeezed into the area of a TSOP6 package. AAT8308 Features * * * VDS(MAX) = -20V ID(MAX) 1 = -4.5A @ 25C Low RDS(ON): * 60 m @ VGS = -4.5V * 110 m @ VGS = -2.5V TSOPJW-8 Package Advanced Information Applications * * * * Battery Packs Cellular & Cordless Telephones Battery-powered portable equipment Load Switches D 8 Top View D 7 D 6 D 5 1 S 2 S 3 S 4 G Absolute Maximum Ratings Symbol VDS VGS ID IDM IS PD TJ, TSTG (TA=25C unless otherwise noted) Value -20 12 4.5 3.6 24 -1.3 2.0 1.3 -55 to 150 Description Drain-Source Voltage Gate-Source Voltage Continuous Drain Current @ TJ=150C 1 Units V TA = 25C TA = 70C 1 Pulsed Drain Current 2 Continuous Source Current (Source-Drain Diode) Maximum Power Dissipation 1 A TA = 25C TA = 70C W C Operating Junction and Storage Temperature Range Thermal Characteristics Symbol RJA RJA2 RJF Description Junction-to-Ambient steady state Junction-to-Ambient t<5 seconds Junction-to-Foot 1 1 1 Typ 92 50 33 Max 112 62 40 Units C/W C/W C/W 8308.2003.06.0.63 1 20V P-Channel Power MOSFET Electrical Characteristics Symbol Description (TJ=25C unless otherwise noted) Conditions Min -20 48 85 -24 -0.6 100 -1 -5 7 7.1 1.8 2.9 TBD TBD TBD TBD -1.3 -1.3 60 110 AAT8308 Typ Max Units V m A V nA A S DC Characteristics BVDSS Drain-Source Breakdown Voltage VGS=0V, ID=-250A VGS=-4.5V, ID=-4.5A RDS(ON) Drain-Source ON-Resistance 2 VGS=-2.5V, ID=-3.3A ID(ON) On-State Drain Current 2 VGS=-4.5V, VDS=-5V (Pulsed) VGS(th) Gate Threshold Voltage VGS=VDS, ID=-250A IGSS Gate-Body Leakage Current VGS=12V, VDS=0V VGS=0V, VDS=-20V IDSS Drain Source Leakage Current VGS=0V, VDS=-16V, TJ=70C 3 gfs Forward Transconductance 2 VDS=-5V, ID=-4.5A Dynamic Characteristics 3 QG Total Gate Charge VDS=-10V, RD=2.2, VGS=-4.5V QGS Gate-Source Charge VDS=-10V, RD=2.2, VGS=-4.5V QGD Gate-Drain Charge VDS=-10V, RD=2.2, VGS=-4.5V tD(ON) Turn-ON Delay VDS=-10V, VGS=-4.5V, RD=2.2, tR Turn-ON Rise Time VDS=-10V, VGS=-4.5V, RD=2.2, tD(OFF) Turn-OFF Delay VDS=-10V, VGS=-4.5V, RD=2.2, tF Turn-OFF Fall Time VDS=-10V, VGS=-4.5V, RD=2.2, Source-Drain Diode Characteristics VSD Source-Drain Forward Voltage 2 VGS=0, IS=-4.5A IS Continuous Diode Current 1 nC RG=6 RG=6 RG=6 RG=6 ns V A Note 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. RJF + RFA = RJA where the foot thermal reference is defined as the normal solder mounting surface of the device's leads. RJF is guaranteed by design, however RCA is determined by the PCB design. Actual maximum continuous current is limited by the application's design. Note 2: Pulse test: Pulse Width = 300 s Note 3: Guaranteed by design. Not subject to production testing. 2 8308.2003.06.0.63 20V P-Channel Power MOSFET Ordering Information Package TSOPJW-8 Marking Part Number (Tape and Reel) AAT8308ITS-T1 AAT8308 Package Information TSOPJW-8 0.325 0.075 2.40 0.10 0.65 BSC 0.65 BSC 0.65 BSC 2.85 0.20 7 3.025 0.075 0.9625 0.0375 1.0175 0.0925 0.04 REF 0.055 0.045 0.010 0.15 0.05 0.45 0.15 2.75 0.25 All dimensions in millimeters. 8308.2003.06.0.63 3 20V P-Channel Power MOSFET AAT8308 AnalogicTech cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in an AnalogicTech product.
