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 V IN ≤ 1.5V + VBIAS and VBIAS is within the voltage range from 3.2V to 5.5V. On-resistance of load switch will be higher if VIN + 1.5V > VBIAS. Resistance curves of a typical sample device at different VBIAS = VIN at IOUT = -200mA are shown as below. Applications Information The basic DML1007LDS application circuit is shown in the second page. Component selection is explained below. Input Capacitor A capacitor of 10μF or higher value is recommended to be placed close to the IN pins of DML1007LDS. 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. Output Capacitor A capacitor of 0.1μF or higher value is recommended to be placed between the OUT pins and GND. The switching times are affected by the capacitance. A larger capacitor makes the initial turn-on transient smoother. This capacitor must be large enough to supply a fast transient load in order to prevent the output from dropping. Thermal Considerations To ensure proper operation, the maximum junction temperature of the DML1007LDS should not exceed +150°C. Several factors attribute to the junction temperate rise: load current, MOSFET on-resistance, junction-to-ambient thermal resistance, and ambient temperature. The maximum load current can be determined by: It is noted that the maximum continuous load current is 6A. Layout Guidelines Good PCB is important for improving the thermal performance of DML1007LDS. 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.
