| 20V P-Channel Power MOSFET General Description The AAT7551 is a dual low threshold MOSFET designed for the battery, cell phone, and PDA markets. Using AnalogicTechTM's ultra high density MOSFET 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 a SC70 package. AAT7551 Features * * * VDS(MAX) = -20V ID(MAX) 1 = -2.7A @ 25C Low RDS(ON): * 100 m @ VGS = -4.5V * 175 m @ VGS = -2.5V Dual SC70JW-8 Package Applications * * * Battery Packs Cellular & Cordless Telephones Battery-powered portable equipment D1 8 Preliminary Information Top View D1 7 D2 6 D2 5 1 S1 2 G1 3 S2 4 G2 Absolute Maximum Ratings Symbol VDS VGS ID IDM IS PD TJ, TSTG (TA=25C unless otherwise noted) Value -20 12 2.7 2.2 8 -0.6 1.2 0.75 -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 1 Junction-to-Ambient t<5 seconds 1 Junction-to-Foot 1 Typ 132 83 60 Max 165 104 72 Units C/W 7551.2003.08.0.61 1 20V P-Channel Power MOSFET Electrical Characteristics Symbol Description (TJ=25C unless otherwise noted) Conditions VGS=0V, ID=-250A VGS=-4.5V, ID=-2.7A VGS=-2.5V, ID=-2.0A VGS=-4.5V, VDS=-5V (Pulsed) VGS=VDS, ID=-250A VGS=12V, VDS=0V VGS=0V, VDS=-20V VGS=0V, VDS=-16V, TJ=70C 3 VDS=-5V, ID=-2.7A VDS=-10V, VDS=-10V, VDS=-10V, VDS=-10V, VDS=-10V, VDS=-10V, VDS=-10V, 2 AAT7551 Min -20 Typ Max Units V DC Characteristics BVDSS Drain-Source Breakdown Voltage RDS(ON) ID(ON) VGS(th) IGSS IDSS Drain-Source ON-Resistance On-State Drain Current 2 Gate Threshold Voltage Gate-Body Leakage Current Drain Source Leakage Current 2 80 140 -8 -0.6 100 175 m A V nA A S 100 -1 -5 4 5.9 1 2 22 10 20 40 -1.3 -0.6 gfs Forward Transconductance 2 Dynamic Characteristics 3 QG Total Gate Charge QGS Gate-Source Charge QGD Gate-Drain Charge tD(ON) Turn-ON Delay tR Turn-ON Rise Time tD(OFF) Turn-OFF Delay tF Turn-OFF Fall Time Source-Drain Diode Characteristics VSD Source-Drain Forward Voltage IS Continuous Diode Current 1 RD=3.7, RD=3.7, RD=3.7, RD=3.7, RD=3.7, RD=3.7, RD=3.7, VGS=-4.5V VGS=-4.5V VGS=-4.5V VGS=-4.5V, VGS=-4.5V, VGS=-4.5V, VGS=-4.5V, nC RG=6 RG=6 RG=6 RG=6 ns VGS=0, IS=-2.7A 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 7551.2003.08.0.61 20V P-Channel Power MOSFET Typical Characteristics (TJ = 25C unless otherwise noted) Output Characteristics 8 AAT7551 Transfer Characteristics 8 5V 4.5V 4V 3.5V 3V 2.5V ID (A) 6 VD=VG 25C -55C 125C 6 IDS (A) 4 4 2V 2 2 1.5V 0 0 0.5 1 1.5 2 2.5 3 0 0 1 2 3 4 5 VDS (V) VGS (V) On-Resistance vs. Drain Current 0.3 0.25 On-Resistance vs. Gate to Source Voltage 0.4 ID = 2.7A 0.3 RDS(ON) () 0.2 VGS = 2.5 V 0.15 0.1 0.05 0 0 2 4 6 8 RDS(ON) () 0.2 0.1 VGS = 4.5 V 0 0 1 2 3 4 5 ID (A) VGS (V) On-Resistance vs. Junction Temperature 1.6 1.5 0.4 Threshold Voltage ID = 250A Normalized RDS(ON) 1.4 1.3 1.2 1.1 1.0 0.9 0.8 0.7 0.6 VGS(th) Variance (V) VGS = 4.5V ID = 2.7A 0.3 0.2 0.1 0 -0.1 -0.2 -0.3 -50 -25 0 25 50 75 100 125 150 -50 -25 0 25 50 75 100 125 150 TJ (C) TJ (C) 7551.2003.08.0.61 3 20V P-Channel Power MOSFET Typical Characteristics (TJ = 25C unless otherwise noted) Gate Charge 5 4 3 2 1 0 0 1 2 3 4 5 6 AAT7551 Source-Drain Diode Forward Voltage 100 VD = 10V ID = 2.7A 10 VGS (V) IS (A) 1 TJ = 150C 0.1 0 0 .2 0.4 0 .6 0.8 TJ = 25C 1 1.2 QG, Charge (nC) VSD (V) Capacitance 600 Single Pulse Power, Junction to Ambient 50 45 Capacitance (pF) Ciss Power (W) 400 40 35 30 25 20 15 10 5 0 0.0001 200 Crss Coss 0 0 5 10 15 20 0.001 0.01 0.1 1 10 100 1000 VDS (V) Time (s) Transient Thermal Response, Junction to Ambient Normalized Effective Transient Thermal Impedance 10 1 .5 .2 0.1 .1 .02 .01 0.01 Single Pulse 0.001 0.01 0.1 1 10 100 1000 0.0001 Time (s) 4 7551.2003.08.0.61 20V P-Channel Power MOSFET Ordering Information Package SC70JW-8 Marking1 KDXYY Part Number (Tape and Reel) AAT7551IJS-T1 AAT7551 Note 1: XYY = assembly and date code.
