AO4832 Common-Drain Dual N-Channel Enhancement Mode Field Effect Transistor General Description The AO4832 uses advanced trench technology to provide excellent RDS(ON), low gate charge and operation with gate voltages as low as 2.5V. This device is suitable for use as a load switch or in PWM applications. Standard Product AO4832 is Pb-free (meets ROHS & Sony 259 specifications). AO4832L is a Green Product ordering option. AO4832 and AO4832L are electrically identical. Features VDS (V) = 30V ID = 8 A (VGS = 10V) RDS(ON) < 15m (VGS = 10V) RDS(ON) < 17m (VGS = 4.5) RDS(ON) < 23m (VGS = 2.5V) TSSOP-8 Top View D1/D2 S1 S1 G1 1 2 3 4 8 7 6 5 D1/D2 S2 S2 G2 D1 D2 G1 S1 G2 S2 Absolute Maximum Ratings TA=25C unless otherwise noted Parameter Symbol VDS Drain-Source Voltage VGS Gate-Source Voltage Continuous Drain Current A Pulsed Drain Current Power Dissipation A B Maximum 30 12 8 6 30 1.5 1 -55 to 150 Units V V A TA=25C TA=70C TA=25C TA=70C ID IDM PD TJ, TSTG W C Junction and Storage Temperature Range Thermal Characteristics Parameter Maximum Junction-to-Ambient A Maximum Junction-to-Ambient A Maximum Junction-to-Lead C Symbol t 10s Steady-State Steady-State RJA RJL Typ 64 89 53 Max 83 120 70 Units C/W C/W C/W Alpha & Omega Semiconductor, Ltd.

Copper, in a still air environment with TA =25C. The 20 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 JA is the sum of the thermal impedence from junction to lead RJL and lead to ambient. D. The static characteristics in Figures 1 to 6,12,14 are obtained using 80 s pulses, duty cycle 0.5% max. E. These tests are performed with the device mounted on 1 in 2 FR-4 board with 2oz. Copper, in a still air environment with TA=25C. The SOA curve provides a single pulse rating. Rev2: August 2005 THIS PRODUCT HAS BEEN DESIGNED AND QUALIFIED FOR THE CONSUMER MARKET.
