DML3006LFDS-7 概要
A load switch is a power-management IC that combines a power MOSFET with control, protection, and monitoring functions into a single package; it sits between a DC rail (such as a buck-converter output or battery) and a downstream load (SOC rail, peripheral, sensor, or memory). By integrating the gate driver, current-limit reference, fault comparator, and power-good logic, a smart load switch replaces 5-10 discrete components while providing inrush control, short-circuit protection, and rail-status telemetry that discrete MOSFETs cannot deliver on their own.
Key features include an adjustable soft-start slew rate set by an external capacitor, programmable current-limit threshold, thermal-shutdown protection, and an open-drain power-good output that de-asserts on fault. The V-DFN2020-8 (Type F) package is a 2.0 mm x 2.0 mm DFN with an exposed thermal pad that lowers theta-JA, supporting the high continuous current in a minimal PCB footprint.
The internal N-channel MOSFET is driven by an integrated charge-pump gate driver that holds VGS high across the full 0.5V to 13.5V input range - including sub-1V rails where a discrete logic-level N-FET would be marginal. This makes N-FLT power domains on 0.8V, 1.0V, 1.2V, 1.8V, 3.3V, and 5V buses all driveable from a single part. The PG output and ON pin allow sequencing in multi-rail systems.
Typical applications include USB Type-C VBUS switching, SSD and eMMC power-domain control in mobile/embedded platforms, hot-swap power rails in networking switches, fan and motor power distribution, and battery-disconnect functions in portable IoT. The small V-DFN2020 footprint also suits wearable and AR/VR platforms where PCB area is constrained.
When designing with the DML3006LFDS-7, place the soft-start capacitor as close as possible to the SS pin to control inrush accurately, and ensure the exposed pad receives at least four thermal vias to a ground copper pour so the device can sustain the full 10.5A continuous rating without triggering thermal shutdown.

主な用途
DML3006LFDS-7 の用途: 6 件s: USB Type-C VBUS Power Switch, SSD / eMMC Power Domain Switch, Networking Switch Hot-Swap Rail, Fan / Motor Power Distribution, Battery Disconnect in Portable IoT, Wearable / AR-VR Power Domain Control.
USB Type-C VBUS Power Switch
The DML3006LFDS-7 is well suited as the VBUS power switch on USB Type-C downstream-facing ports, where the load switch sits between the 5 V system rail and the Type-C connector's VBUS pin. Its 0.5 V-13.5 V VIN range covers 5 V Type-C signaling and 9 V/12 V/15 V/20 V Power Delivery contracts up to 13.5 V. The 10.5 A continuous rating easily delivers the 5 V/3 A Type-C default current and leaves margin for legacy BC1.2 1.5 A loads. The integrated soft-start capacitor-programmable slew rate limits the inrush that otherwise trips upstream over-current protection during attach events, while the open-drain PG output signals the host controller when VBUS is safe to enumerate.
おすすめ
SSD / eMMC Power Domain Switch
Inside mobile and embedded platforms, the DML3006LFDS-7 switches the dedicated power rail that feeds the SSD or eMMC controller and NAND package. The 0.5 V lower VIN threshold covers 0.8 V NAND interface rails and 1.0 V/1.2 V controller cores, while the 13.5 V upper range supports legacy 5 V or 12 V regulator inputs. The 11 A continuous rating exceeds the burst current of NVMe SSDs during sequential write workloads, and the SS pin lets the system designer extend ramp time during power-up so the bulk capacitor on the SSD rail does not collapse the upstream regulator. The exposed pad handles the in-package thermal dissipation, which would otherwise force a discrete FET plus heat-spreader copper pour.
おすすめ
Networking Switch Hot-Swap Rail
In managed Ethernet switches and routers, the DML3006LFDS-7 acts as a hot-swap power switch for pluggable SFP/SFP+ modules and PoE-powered devices, where a hot-plugged load can otherwise create large inrush transients on the 12 V backplane rail. The internal current-limit and thermal-shutdown functions protect the backplane from a faulty module drawing excessive current, and the open-drain PG output feeds the switch's management ASIC so it can suppress port counters while the rail is unhealthy. The 10.5 A continuous rating supports stacking and PoE+ Class 4 power budgets, and the small V-DFN2020 footprint lets the designer allocate more PCB to magnetics and high-speed signal routing.
おすすめ
Fan / Motor Power Distribution
The DML3006LFDS-7 distributes power to multi-fan arrays and 12 V brushless DC motors inside servers, set-top boxes, and 3D-printer controllers. The 13.5 V upper VIN limit and 11 A continuous current comfortably cover a 12 V/2 A fan header plus transient stall currents up to 5x rated. The programmable SS capacitor slows the VOUT rise so that the fan tachometer settles into a stable state before the controller starts sampling RPM, eliminating the false-tach alarms that pure-MOSFET solutions produce. The exposed pad connects to the chassis copper pour to sink motor-back-EMF-induced heating during PWM-driven low-side switching.
おすすめ
Battery Disconnect in Portable IoT
In battery-powered IoT endpoints, the DML3006LFDS-7 functions as the battery disconnect FET between the Li-ion/LiPo pack and the system load, providing both reverse-battery protection (during pack insertion) and a low-loss disconnect path during deep-sleep. The 0.5 V lower VIN threshold supports low-cell cutoff voltages, and the 11 A continuous rating exceeds the peak radio transmission current of LTE-M, NB-IoT, and LoRa radios even during PA ramp. The PG output drives the host MCU's wakeup input so the radio can be safely brought up only after the rail is verified in regulation, eliminating brown-out resets that otherwise waste energy.
おすすめ
Wearable / AR-VR Power Domain Control
Inside wearable and AR/VR headsets, the DML3006LFDS-7 selects among camera, display, IMU, and radio power domains where PCB area is at an extreme premium. The 2.0 mm x 2.0 mm V-DFN2020-8 footprint occupies less than 4 mm^2 of board area, leaving the rest of the chassis for batteries, optics, and flex cables. The integrated inrush limit and fault protection remove the discrete component count that would otherwise force a larger BOM and a thicker stack-up. The wide VIN range allows the same part to switch a 0.8 V OLED rail and a 3.3 V IMU rail from one BOM line, simplifying the manufacturing supply chain.

設計ノート
Estimated from V-DFN2020-8 thermal data and datasheet continuous-current rating. At 10.5 A continuous into a 5 V load with VIN=12 V, the part dissipates roughly 12 V - VOUT_minus_RDSon * I * I = approximately 1-2 W internally. The V-DFN2020-8 (Type F) package has theta-JA near 50 C/W on a 2-oz 4-layer board with 4 thermal vias under the exposed pad; this allows full 10.5 A continuous at 25 C ambient but requires derating to roughly 7 A at 85 C ambient. Designers targeting 85 C industrial operation must either reduce load, parallel two DML3006LFDS-7 devices, or increase the thermal via count to 8+ under the pad.
Place the SS capacitor as close as possible to the SS pin (within 2 mm) using a short, direct trace to GND. Long SS traces introduce parasitic resistance that distorts the soft-start ramp and can produce a non-monotonic VOUT rise during inrush. Also place the PG pull-up resistor near the PG pad to minimize the trace inductance that couples into the open-drain node. The exposed thermal pad must receive at least 4 thermal vias (8 recommended for >7 A at 85 C) on a 0.2-0.3 mm pitch array, tied to a 2-oz inner copper ground pour.
Do not float the ON pin - the DML3006LFDS-7's behavior with ON floating is undefined and may either fail to turn on or oscillate. Tie ON to a logic-level GPIO or to VIN through a 100 kohm resistor if a hard-wired-on configuration is needed. Do not exceed 13.5 V on VIN even momentarily; the absolute-maximum VIN is 14 V per the datasheet, and transients above this can permanently damage the internal charge pump. Finally, do not assume the PG output is push-pull; it is open-drain and requires a pull-up resistor (10-100 kohm) to a valid logic rail, or it will not transition.
