Product details
Overview
DML1010FDK from Diodes Incorporated is a single-channel smart load switch featuring an integrated N-channel MOSFET with 8 mΩ RDS(ON) at 5 V VBIAS, 6 A continuous current rating, and operation across 0.8 V to (VBIAS − 1.5 V) input voltage range. It serves as a high-efficiency power-path controller in portable electronics, enabling precise ON/OFF control of downstream rails via a logic-level enable signal.
For engineers reviewing the DML1010FDK datasheet, DML1010FDK pinout, DML1010FDK application, or DML1010FDK equivalent, key selection criteria include ultra-low on-resistance at sub-1.1 V input, integrated quick-output discharge, 35 µA quiescent current, and compatibility with 3.2–5.5 V bias supplies in space-constrained U-DFN2020-8 packages.
Technical Context
The DML1010FDK implements a fixed-threshold, active-high enable architecture with internal charge pump and gate driver optimized for low-VIN operation down to 0.8 V. Its bias supply (VBIAS) powers all internal logic and gate drive circuitry independently of the switched rail.
It integrates a 200 Ω pull-down resistor on the OUT pin for controlled discharge during turn-off, eliminating external components. Thermal design relies on the exposed pad (EPAD) for junction-to-case conduction (θJC = 8 °C/W), requiring PCB copper thermal vias for sustained 6 A operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(ON) | 8 mΩ max at VBIAS = 5 V, VIN = 1.05 V, TA = +85 °C - enables <10 mV drop at 1.25 A, critical for low-voltage core rails |
| Continuous Current | 6 A - supports high-current peripherals like USB-C PD ports or SSD power rails without external heatsinking |
| VIN Range | 0.8 V to (VBIAS − 1.5 V) - allows direct switching of 1.05 V I/O domains powered from 2.5 V or 3.3 V bias rails |
| VBIAS Range | 3.2 V to 5.5 V - compatible with standard system bias supplies; independent of switched rail voltage |
| tR (Rise Time) | 5–33 µs typical - ensures controlled inrush limiting for capacitive loads up to 100 µF |
| IQ | 35 µA max at VON = 5 V - minimizes standby power loss in always-on subsystems |
| Output Discharge | Integrated 200 Ω pull-down - discharges output to <0.1 V within 100 µs after turn-off, preventing floating states |
Pinout & Package
Supplied in an 8-pin U-DFN2020-8 (Type K) package with 0.5 mm pitch and thermally enhanced EPAD. Dimensions: 2.0 × 2.0 × 0.6 mm (max), moisture sensitivity level 1 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, EPAD | IN | Main power input terminal; EPAD must be soldered to PCB ground plane for thermal and electrical integrity |
| 3 | VBIAS | Bias supply input for internal logic and gate driver; decoupling capacitor required |
| 4 | ON | Active-high enable control; requires ≥1.2 V logic high to activate switch; must not float |
| 5 | GND | Signal ground reference for control logic and internal circuitry |
| 6, 7, 8 | OUT | Switched output terminal; connects to load; integrated 200 Ω discharge path to GND |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low RDS(ON) | 8 mΩ at 5 V VBIAS enables <7.5 mW conduction loss at 6 A - reduces thermal stress in compact layouts |
| Sub-1 V input support | Operates down to 0.8 V VIN while maintaining regulation - essential for modern low-voltage SoC I/O domains |
| Integrated quick discharge | 200 Ω internal pull-down eliminates need for external resistor - saves board area and BOM count |
| Low quiescent current | 35 µA IQ at full bias - extends battery life in always-on monitoring circuits |
| Robust ESD protection | 2 kV HBM / 1 kV CDM - meets industrial-grade reliability requirements without external TVS |

Equivalent & Alternatives
The following parts are listed as comparable options for similar load switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS22919DBVR | Higher RDS(ON) (12 mΩ @ 5 V), no integrated discharge, 1.8–5.5 V VIN range | Requires external 100 Ω discharge resistor; unsuitable for <1 V rails | Select if bias supply is shared with VIN and discharge timing is non-critical |
| AP22653AW5-7 | Lower current rating (4 A), 15 mΩ RDS(ON) @ 5 V, 0.5–5.5 V VIN, no EPAD | Limited thermal performance above 3 A; lacks exposed pad for high-current stability | Prefer for cost-sensitive, lower-current (<4 A) applications where board space is less constrained |
Compared with TPS22919DBVR and AP22653AW5-7, the DML1010FDK uniquely supports sub-1 V inputs with ultra-low RDS(ON) and integrated thermal management via EPAD - making it optimal for high-density, high-current, low-voltage power gating in portable and embedded systems.

FAQ
What is the minimum input voltage supported by the DML1010FDK?
The DML1010FDK supports input voltages as low as 0.8 V, provided the bias supply (VBIAS) is within its 3.2–5.5 V range and satisfies VIN ≤ VBIAS − 1.5 V. At VBIAS = 5 V, this allows operation down to 1.05 V; at VBIAS = 3.2 V, minimum VIN is 0.8 V. This capability is verified per DS40878 Rev. 3 Section 6.2.
Does the DML1010FDK require external components for basic operation?
No external components are required for basic enable/disable functionality. However, Diodes recommends a ≥10 µF input capacitor near pins 1/2, a ≥0.1 µF output capacitor between pins 6–8 and GND, and a 1 µF bypass capacitor on VBIAS (pin 3) to ensure stable switching and minimize voltage droop during inrush, as specified in Section 8.1 of the datasheet.
How does the integrated output discharge function work?
The DML1010FDK includes a 200 Ω internal pull-down resistor between OUT and GND, activated automatically when the ON pin is driven low. This discharges the output capacitance to <0.1 V within ~100 µs (typical), preventing floating states and ensuring clean power-down sequencing without external circuitry, as confirmed in Electrical Characteristics Table 1 and Application Information Section 8.4.
Is the DML1010FDK qualified for automotive applications?
The DML1010FDK is not AEC-Q100 qualified. Diodes explicitly states that automotive-grade versions require specific change control, PPAP capability, and IATF 16949 manufacturing - and directs customers to contact their local representative for such variants. The standard DML1010FDK-7 is intended for industrial, computing, and consumer applications only.
