Product details
Overview
DML1008LDS from Diodes Incorporated is a single-channel smart load switch featuring an integrated N-channel MOSFET, 6A continuous current capability, 8mΩ RDS(ON) at 5V VBIAS/1.05V VIN, 3.2–5.5V bias supply range, and 10µs turn-on rise time. It enables power rail control in space-constrained portable electronics with ultra-low quiescent current (35µA) and integrated quick output discharge.
For engineers reviewing the DML1008LDS datasheet, DML1008LDS pinout, DML1008LDS application, or DML1008LDS equivalent, key selection criteria include input voltage compatibility (0.8V to VBIAS−1.5V), thermal performance (θJA = 60°C/W), on-resistance stability across bias conditions, and V-DFN3030-8 package layout requirements for high-current PCB routing.
Technical Context
The DML1008LDS implements a bias-supplied N-channel MOSFET architecture where VBIAS powers internal logic and gate drive, enabling operation with low VIN (down to 0.8V) while maintaining low RDS(ON). Its active-high ON pin includes an internal pull-down resistor, eliminating external biasing components.
It integrates a 200Ω output pull-down resistor for controlled discharge, supports power sequencing flexibility (VVBIAS→VIN→VON or VIN→VVBIAS→VON), and delivers specified switching times only when VBIAS is within 3.2–5.5V and VIN ≤ VBIAS − 1.5V - violating this constraint increases RDS(ON) significantly.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Continuous Current | 6A - supports high-current rails such as SSD power domains or CPU core voltage sequencing without external heatsinking under typical ambient conditions. |
| RDS(ON) | 8mΩ @ VBIAS=5V, VIN=1.05V, TA=+85°C - limits conduction loss to <50mW at 6A, critical for thermal management in compact portable designs. |
| VBIAS Range | 3.2V to 5.5V - defines required auxiliary supply rail; operation outside this range disables internal logic and invalidates all timing specs. |
| VIN Range | 0.8V to VBIAS−1.5V - constrains usable input voltage based on bias setting; e.g., at VBIAS=3.3V, max VIN=1.8V. |
| tR (Rise Time) | 5–33µs - determines slew rate of output voltage ramp; impacts inrush current limiting and transient response in downstream LDOs or regulators. |
| IQ | 35µA @ VBIAS=5V, IOUT=0 - enables multi-week battery life in always-on standby circuits without compromising fast wake-up capability. |
| θJA | 60°C/W - requires ≥250mm² copper pour under EPAD and short wide traces to sustain 6A continuous current at +85°C ambient. |
Pinout & Package
Package: V-DFN3030-8 (Type R), 3.0×3.0×0.8mm, exposed thermal pad (EPAD) connected to IN pins internally; moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, EPAD | IN | Main power input; EPAD must be soldered to large copper area tied to IN net for thermal dissipation and low-inductance return path. |
| 3 | VBIAS | Bias supply input for internal logic and gate driver; decoupling capacitor (CVBIAS) required near pin. |
| 4 | ON | Active-high enable; internal 100kΩ pull-down ensures safe default-OFF state; logic threshold: VONH ≥ 1.2V, VONL ≤ 0.5V. |
| 5 | GND | Signal ground reference; separate from power ground; connect to PCB signal plane, not directly to high-current return paths. |
| 6, 7, 8 | OUT | Switched output; parallel pins reduce trace inductance and resistance; must route with low-impedance path to load. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(ON) | 8mΩ at 5V VBIAS enables <50mW conduction loss at full 6A load, reducing thermal stress in thin-profile consumer devices. |
| Integrated Quick Output Discharge | 200Ω internal pull-down discharges output capacitance rapidly upon disable, preventing floating states and ensuring clean power-down sequencing. |
| Low-Voltage Input Operation | Supports 0.8V minimum VIN - compatible with advanced low-voltage SoCs and memory interfaces requiring sub-1V rail control. |
| No External Components Required | On-chip control logic, driver, bias regulation, and discharge FET eliminate need for discrete gate resistors, pull-ups, or discharge MOSFETs. |
| Thermally Optimized Package | V-DFN3030-8 with exposed pad achieves θJC = 8°C/W when properly mounted - enables direct heat transfer to PCB copper for high-current reliability. |
Applications
| SSD Power Management | Notebook Subsystem Enable |
|---|---|
|
Use Scenario: Enables/disables 3.3V or 1.8V power rails to NVMe SSD modules during sleep/wake transitions.

| Industrial Gateway Power Isolation | Medical Imaging Sensor Interface |
|
Use Scenario: Isolates 5V Ethernet PHY or cellular modem power domain from main system rail in ruggedized gateways. IC Role / Device Role / Timing Role: Fault-tolerant load switch with robust 12A pulsed current rating (IPLS) for surge immunity during hot-plug events. Use Value: Withstands 2kV HBM ESD and operates over −40°C to +85°C, meeting industrial environmental requirements without derating. |
Use Scenario: Supplies regulated 1.2V or 1.8V to CMOS image sensor arrays in portable ultrasound or endoscope systems. IC Role / Device Role / Timing Role: Low-noise, low-RDS(ON) switch minimizing voltage droop during sensor frame capture bursts. Use Value: 8mΩ RDS(ON) limits output sag to <50mV at 6A peak, preserving ADC reference stability and image SNR. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS22916BLYFPR | 4.5A rated, 12mΩ RDS(ON) @ 5V, no integrated discharge FET, requires external 100kΩ pull-down on EN. | Limited to lower-current rails; lacks quick discharge, requiring external circuitry for clean power-down in imaging sensors. | Select when cost sensitivity outweighs discharge requirement and current demand stays below 4.5A. |
| RT9711CGJ5 | 5A rated, 15mΩ RDS(ON) @ 5V, 1.8–5.5V VIN range, no VBIAS pin - simpler single-supply operation but higher RDS(ON). | Suitable for fixed-rail applications (e.g., 3.3V-only systems); cannot support sub-1V inputs like DML1008LDS's 0.8V minimum. | Choose for simplified design where input voltage is stable ≥1.8V and 15mΩ loss is acceptable. |
Compared with TPS22916BLYFPR and RT9711CGJ5, the DML1008LDS uniquely combines 6A capacity, sub-1V input support, integrated discharge, and 8mΩ RDS(ON) - making it optimal for next-generation portable SSDs and low-voltage AI edge modules where efficiency, size, and sequencing precision are co-critical.

FAQ
What is the maximum allowable junction temperature for the DML1008LDS?
The absolute maximum junction temperature (TJ) is +150°C. Sustained operation above this limit risks permanent device failure. Thermal design must ensure TJ = TA + (I2 × RDS(ON) × θJA) remains below 150°C - for example, at 6A, 8mΩ, and +85°C ambient, θJA must be ≤45°C/W with proper PCB copper area.
Can the DML1008LDS operate with VBIAS = 3.2V and VIN = 2.0V?
No - the datasheet specifies VIN must not exceed VBIAS − 1.5V. At VBIAS = 3.2V, the maximum allowed VIN is 1.7V. Using 2.0V violates this constraint, increasing RDS(ON) beyond specification and potentially causing thermal runaway at high load currents.
Is an external capacitor required on the VBIAS pin?
Yes - a ceramic decoupling capacitor (CVBIAS) is mandatory on the VBIAS pin, placed as close as possible to the pin. Diodes recommends ≥1µF X7R ceramic to suppress noise and stabilize internal gate drive voltage, especially during fast switching transients.
Does the DML1008LDS support reverse current blocking?
No - the DML1008LDS uses a single N-channel MOSFET configured for forward conduction only. It does not provide reverse current protection; if reverse voltage or backfeed is possible in the application, an additional Schottky diode or dedicated reverse-blocking load switch is required.
