Product details
Overview
DML1012LDS-7A from Diodes Incorporated is a single-channel smart load switch featuring an integrated N-channel MOSFET, 6A continuous current capability, 8 mΩ RDS(ON) at VBIAS = 5V and TA = +85°C, 3.2–5.5V bias supply range, and active-high ON control. It operates with input voltages as low as 0.8V and includes integrated quick output discharge for controlled power-down in portable computing and SSD power rails.
For engineers reviewing the DML1012LDS-7A datasheet, DML1012LDS-7A pinout, DML1012LDS-7A application, or DML1012LDS-7A equivalent, key selection criteria include ultra-low on-resistance under low-VIN conditions, fast 10 µs turn-on rise time, thermal performance in V-DFN3030-8 (Type R), and compatibility with 1.05V input rails in space-constrained embedded systems.
Technical Context
The DML1012LDS-7A implements a self-contained load switch architecture with internal gate driver, bias regulator, and discharge FET-eliminating external components. Its control logic accepts 1.2V minimum high-level ON signal and supports fixed power sequencing (VBIAS → VIN → VON) to ensure specified timing behavior.
Thermal design relies on the exposed pad (EPAD) connected to IN for heat conduction, with θJA = 60°C/W and θJC = 8°C/W. The device maintains stable RDS(ON) across -40°C to +85°C ambient when VBIAS ≥ 3.2V and VIN ≤ VBIAS – 1.5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 8 mΩ max at VBIAS = 5V, VIN = 1.05V, TA = +85°C - enables <10 mV drop at 1.25A, critical for sub-1.2V rail integrity |
| Continuous Current | 6 A - supports high-current peripherals like NVMe SSDs without external heatsinking in compact layouts |
| VBIAS Range | 3.2V to 5.5V - powers internal logic and gate drive independently of low-VIN rails (e.g., 1.05V DDR memory supplies) |
| tR (Rise Time) | 10 µs typ - ensures clean voltage ramp-up for sensitive downstream circuits without overshoot or ringing |
| IQ | 28 µA max - minimizes standby power loss in battery-powered systems during sleep modes |
| Quick Output Discharge | Integrated 200 Ω pull-down - discharges output capacitance within microseconds after turn-off, preventing floating states |
| ESD Rating | 2 kV HBM / 1 kV CDM - meets industrial handling requirements without additional protection circuitry |
Pinout & Package
Package: V-DFN3030-8 (Type R), 3.0 mm × 3.0 mm × 0.8 mm, exposed thermal pad (EPAD) tied to IN pin for enhanced thermal dissipation. RoHS-compliant, halogen-free, NiPdAu-plated terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, EPAD | IN | Main power input; EPAD must be soldered to IN copper pour for thermal and electrical continuity |
| 3 | VBIAS | Bias supply for internal logic and gate driver - decoupled with ≥1 µF capacitor |
| 4 | ON | Active-high enable; requires ≥1.2V logic high to activate switch; must not float |
| 5 | GND | Signal ground reference for control logic and discharge FET |
| 6, 7, 8 | OUT | Switched output; paralleled pins reduce resistance and inductance for 6A delivery |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(ON) at low VIN | 8 mΩ @ VIN = 1.05V - preserves voltage headroom on core logic rails where margin is <100 mV |
| Integrated quick output discharge | 200 Ω internal pull-down - eliminates need for external resistor network, saving PCB area and BOM count |
| Low quiescent current | 28 µA - extends battery life in always-on subsystems (e.g., USB-C PD controllers, sensor hubs) |
| Fast switching with controlled edges | 10 µs tR, 0.7 µs tF - reduces EMI generation and avoids false triggering of downstream reset circuits |
| Robust thermal design | θJC = 8°C/W - enables 6A operation at +85°C ambient with minimal board-level copper area |

Equivalent & Alternatives
The following parts are listed as comparable options for similar load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS22916BLYFPR | Lower RDS(ON) (4.7 mΩ @ 3.3V), but only rated for 4A continuous and requires ≥1.2V VIN; no integrated discharge FET | Suitable for 3.3V-only systems with lower current demand; requires external 100 Ω discharge resistor | Select if VIN ≥ 1.2V and thermal budget allows higher RDS(ON) at 1.05V |
| RT9711CGJ5 | Higher RDS(ON) (12 mΩ @ 5V), 5.5V max VBIAS, but supports 0.5V min VIN; includes thermal shutdown | Better for ultra-low-VIN (<1.0V) use cases; lacks quick discharge and has slower 35 µs tR | Prefer when input voltage drops below 0.8V or thermal protection is mandatory |
Compared with TPS22916BLYFPR and RT9711CGJ5, the DML1012LDS-7A uniquely balances 6A capacity, 1.05V-compatible operation, integrated discharge, and 10 µs rise time - making it optimal for space-constrained, high-efficiency SSD and portable computing power rails where both low-VIN and fast transient response are required.

FAQ
What is the minimum input voltage supported by DML1012LDS-7A?
The DML1012LDS-7A supports input voltages down to 0.8V when VBIAS is ≥3.2V. At VBIAS = 5V, it delivers 8 mΩ RDS(ON) with VIN = 1.05V and TA = +85°C. Operation below 0.8V is not characterized or guaranteed per the datasheet.
Can DML1012LDS-7A be used with a 1.2V input rail?
Yes - the device is fully specified for 1.2V input operation when VBIAS is set to 3.2–5.5V. At VIN = 1.2V and VBIAS = 5V, RDS(ON) remains ≤8 mΩ, enabling <10 mV drop at 1.25A, which is ideal for powering low-voltage logic blocks.
Is an external capacitor required on the VBIAS pin?
Yes - a ≥1 µF ceramic capacitor must be placed close to the VBIAS pin (Pin 3) to stabilize the internal bias regulator and prevent oscillation during high-current switching transients. Diodes recommends X5R/X7R dielectrics with low ESR.
Does DML1012LDS-7A provide overcurrent protection?
No - the DML1012LDS-7A does not include overcurrent or short-circuit protection. It is a basic smart load switch with enable control, quick discharge, and low RDS(ON). External current limiting or fusing is required for fault protection in safety-critical designs.
