DML1012ALDSQ Application Information General Description
The DML1012ALDSQ 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 DML1012ALDSQ 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 DML1012ALDSQ 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 DML1012ALDSQ. 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 VIN ≤ 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.
