Application Information
The DML1012LDS is a single channel, 6A load switch in an 8-pin V-DFN3030-8 (Type R) package. To reduce the voltage drop in high current rails, the device implements an ultra-low resistance N-channel MOSFET operated input voltage range from 0.8V to 3.5V. The device has very low leakage current during off state. This prevents downstream circuits from pulling high standby current from the supply. Integrated control logic, driver, power supply and discharge FET eliminate the needs for any external components, which reduce solution size and bill of materials (BOM) count. Enable Control The DML1012LDS 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 is enabled. Similarly, when the ON pin is at logic low level, the MOSFET is disabled. Power Sequencing The DML1012LDS device will function with fixed power sequence, and the performance of output turn-on delay may vary from what is specified. To achieve the specified performance, there are two recommended power sequences: 1.) VBIAS VIN VON 2.) VIN VBIAS VON Input Capacitor A capacitor of 10μF or higher value is recommended to be placed close to the IN pins of DML1012LDS. 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 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 pin. The switching time is 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 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 V IN + 1.5V > VBIAS. Resistance curves of a typical sample device at different V BIAS = VIN at IOUT = -200mA are shown as below. RDS(ON) (mΩ)

DML1012LDS Application Information (continued) Thermal Considerations To ensure proper operation, the maximum junction temperature of the DML1012LDS 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: Where ILOAD(MAX) is the maximum allowable current on load (A). (6A for DML1012LDS) TJ(MAX) is the maximum allowable junction temperature. TC is the case temperature of the device. θJC = 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. The power traces, which are IN trace, OUT trace and GND trace, should be short, wide and directly for minimizing parasitic inductance. 3. 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 th e input or output capacitors. 5. 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. PGND (Power) CIN COUT CVBIAS VOUTVIN GND (Signal) IN VBIAS ON OUT GND IN IN EPAD OUT OUT
