AON4803

AON4803 Dual P-Channel Enhancement Mode Field Effect Transistor General Description The AON4803 uses advanced trench technology to provide excellent R DS(ON), low gate charge and operation with gate voltage as low as 1.8V. This device is suitable for use as a load switch or in PWM applications. Standard Product AON4803 is Pb-free (meets ROHS & Sony 259 specifications). Features VDS (V) = -20V ID = -3.4A (V GS = -4.5V) RDS(ON) < 90mΩ (VGS = -4.5V) RDS(ON) < 120mΩ (VGS = -2.5V) RDS(ON) < 165mΩ (VGS = -1.8V) D1 S1 G1 S2 G2 1 2 3 4 8 7 6 5 D1 D1 D2 D2 D2 G1 S1 G2 S2 DFN3X2-8L Absolute Maximum Ratings TA=25°C unless otherwise noted Parameter Symbol VDS Drain-Source Voltage Gate-Source Voltage TA=25°C Continuous Drain Current A Pulsed Drain Current Power Dissipation Junction and Storage Temperature Range Parameter: Thermal Characteristics MOSFET A t ≤ 10s Maximum Junction-to-Ambient A Steady-State Maximum Junction-to-Ambient C Steady-State Maximum Junction-to-Lead B MOSFET -20 ±8 -3.4 -2.7 -15 1.7 1.1 -55 to 150 Typ 51 88 28 Max 75 110 35 Units V V A VGS TA=70°C TA=25°C TA=70°C ID IDM PD TJ, TSTG Symbol RθJA RθJL W °C Units °C/W Alpha & Omega Semiconductor, Ltd. AON4803 Electrical Characteristics (TJ=25°C unless otherwise noted) Symbol Parameter Conditions ID=-250µA, VGS=0V VDS=-16V, VGS=0V TJ=55°C VDS=0V, VGS=±8V VDS=VGS ID=-250µA VGS=-4.5V, VDS=-5V VGS=-4.5V, ID=-3.4A RDS(ON) Static Drain-Source On-Resistance TJ=125°C VGS=-2.5V, ID=-2.5A VGS=-1.8V, ID=-1.5A gFS VSD IS Forward Transconductance VDS=-5V, ID=-3.4A 4 Diode Forward Voltage IS=-1A,VGS=0V Maximum Body-Diode Continuous Current -0.3 -15 73 103 100 135 7 -0.76 -1 -2 540 VGS=0V, VDS=-10V, f=1MHz VGS=0V, VDS=0V, f=1MHz 72 49 12 6.1 VGS=-4.5V, VDS=-10V, ID=-3.4A 0.6 1.6 10 VGS=-4.5V, VDS=-10V, RL=2.9Ω, RGEN=3Ω IF=-3.4A, dI/dt=100A/µs 2 Min -20 Typ Max Units V STATIC PARAMETERS BVDSS Drain-Source Breakdown Voltage IDSS IGSS VGS(th) ID(ON) Zero Gate Voltage Drain Current Gate-Body leakage current Gate Threshold Voltage On state drain current -1 -5 ±100 -0.65 -1 90 125 120 165 µA nA V A mΩ mΩ mΩ S V A pF pF pF Ω DYNAMIC PARAMETERS Ciss Input Capacitance Coss Crss Rg Output Capacitance Reverse Transfer Capacitance Gate resistance 700 SWITCHING PARAMETERS Qg Total Gate Charge Qgs Gate Source Charge Qgd tD(on) tr tD(off) tf trr Qrr Gate Drain Charge Turn-On DelayTime Turn-On Rise Time Turn-Off DelayTime Turn-Off Fall Time Body Diode Reverse Recovery Time 7.9 nC nC nC ns ns ns ns ns nC 12 44 22 21 7.5 Body Diode Reverse Recovery Charge IF=-3.4A, dI/dt=100A/µs A: The value of R θJA is measured with the device mounted on 1in FR-4 board with 2oz. Copper, in a still air environment with TA =25°C. The value in any given application depends on the user's specific board design. The current rating is based on the t ≤ 10s thermal resistance rating. B: Repetitive rating, pulse width limited by junction temperature. C. The R θJA is the sum of the thermal impedence from junction to lead RθJL and lead to ambient. D. The static characteristics in Figures 1 to 6,12,14 are obtained using 80 µs pulses, duty cycle 0.5% max. 2 E. These tests are performed with the device mounted on 1 in FR-4 board with 2oz. Copper, in a still air environment with TA=25°C. The SOA curve provides a single pulse rating. Rev 0. December 2007 THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
