This prevents downstream circuits from pulling high standby current from the supply. Integrated control logic, driver, power supply and discharge FET eliminates the needs for any external components, which reduce solution size and bill of materials (BOM) count. Enable Control The DML1008LDS device allows for enabling the MOSFET in an active-high configuration. When the VBIAS supply pin has an adequate voltage applied and the ON pin is at logic high level, the MOSFET will be enabled. Similarly, when the ON pin is at logic low level, the MOSFET will be disabled. An internal pull down resistor to ground on the ON pin ensures that the MOSFET will be disabled when not being driven. Power sequencing The DML1008LDS device will function with any power sequence, but the output turn-on delay performance may vary from what is specified. To archives the specified performance, there are two recommended power sequences: 1.) VVBIAS VIN VON 2.) VIN VVBIAS VON Input Capacitor A capacitor of 10F or higher value is recommended to be placed close to the IN pins of DML1008LDS. 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 0.1F or higher value is recommended to be placed between the OUT pins and GND pin. 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. VIN and VVBIAS Voltage Range For optimal on-resistance of load switch, make sure VIN 1.5V + VVBIAS and VVBIAS is within the voltage range from 3.2V to 5.5V. On-resistance of load switch will be higher if VIN + 1.5V > VVBIAS. Resistance curves of a typical sample device at different V VBIAS = VIN at IOUT = -200mA are shown as below.

To reduce the voltage drop in high current rails, the device implements an ultra-low resistance N-channel MOSFET which can be operated input voltage range from 0.8V to 3.5V.

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: Where ILOAD(MAX) is the maximum allowable current on load (A). (6A for DML1008LDS) TJ(MAX) is the maximum allowable junction temperature. TC is the case temperature of the device. JC= junction to case thermal impedance. This parameter is highly dependent upon PCB layout. PCB Layout Consideration 1. Place the input/output capacitors CIN and COUT as close as possible to the IN and OUT pins. 2. 3. The power traces which are IN trace, OUT trace and GND trace. They should be short, wide and directly for minimize parasitic inductance. Place CVBIAS capacitor near the device pin. 4. Connect the signal ground to the GND pin, and keep a single connection from GND pin to the power ground behind the input or output capacitors. For better power dissipation, holes are recommended to connect to the exposed pad's landing area with a large copper polygon on the other side of the printed circuit board. The copper polygons and exposed pad shall connect to IN pin on the printed circuit board. 5.
