Component selection is explained below. The AOZ1334DI-02 is enabled when the ON pin is on active high with 1.2V or above voltage. The device is disabled when the ON pin voltage is 0.5V or lower. The EN input is compatible with both TTL and CMOS logic. VBIAS Voltage Range For optimal on-resistance of load switch, make sure the voltage is within 2.5V to 5.5V. On-resistance of load switch will be higher if the condition is not satisfied. Resistance curves of a typical sample device at VBIAS = VIN and at different output currents are shown as below. 4.3 RDSON (mΩ) 4.1 VBIAS = 2.5V VBIAS = 3.3V VBIAS = 5.0V VBIAS = 5.5V 3.9 Output Capacitor A capacitor of 10μF or higher value is recommended to be place between the OUT pins and GND. The capacitance does not affect the turn-on slew rate. However, a larger capacitor makes the initial turn-on transient smoother. Thermal Considerations To ensure proper operation, the maximum junction temperature of the AOZ1334DI-02 should not exceed 150°C. Several factors attribute to the junction temperate rise: load current, MOSFET on-resistance, junction-toambient thermal resistance, and ambient temperature. The maximum load current can be determined by: 4.2 4.0 Input Capacitor A capacitor of 10μF or higher value is recommended to be place close to the IN pins of AOZ1334DI-02. This capacitor can reduce the voltage drop caused by the in-rush current during the turn-on transient of the load switch. A higher value capacitor can be used to further reduce the voltage drop during high-current application.

Exceeding the maximum continuous load current may cause permanent damage to the device. Good PCB is important for improving the thermal performance of AOZ1334DI-02. Place the input and output bypass capacitors close to the IN and OUT pins. The input and output PCB traces should be as wide as possible for the given PCB space. Use a ground plane to enhance the power dissipation capability of the device. 5.0 4.9 VBIAS = 2.5V VBIAS = 3.3V 4.8 VBIAS = 5.0V VBIAS = 5.5V 4.7 TA = 85ºC 4.6 4.5 4.4 4.3 1 2 3 4 5 6 7 8 9 10 IOUT (A) Rev. 1.1 January 2016 www.aosmd.com Page 9 of 12 AOZ1334DI-02 Package Dimensions, DFN3x3_8L, EP1_S b1 D 8x bbb 8 e b C A B 8 aaa C 2x L E E1 L 1 1 aaa C 2x D1 TOP VIEW Pin1 Identification BOTTOM VIEW ccc C A1 Seating Plane A ddd C SIDE VIEW C RECOMMENDED LAND PATTERN Symbols Min. 1.60 0.40 0.30 0.30 0.65 1.30 2.60 1.60 Dimensions in millimeters 2.40 UNIT: mm A A1 b1 b c D D1 E E1 e L R aaa bbb ccc ddd 0.70 0.00 1.55 0.25 --2.90 2.35 2.90 1.50 Nom. 0.75 0.02 1.60 0.30 0.203 3.00 2.40 3.00 1.60 0.65 BSC 0.35 0.40 0.20 0.15 0.10 0.10 0.08 Max. 0.80 0.05 1.65 0.35 --3.10 2.45 3.10 1.70 0.45 Dimensions in inches Symbols Min.
