Diodes Incorporated DML10M8LDS-7

Overview

DML10M8LDS from Diodes Incorporated is a single-channel smart load switch featuring an integrated N-channel MOSFET, 6A continuous current capability, 8 mΩ R_DS(ON) at V_BIAS = 5V and T_A = +85°C, 3.2–5.5V bias supply range, and active-high ON control. It enables power rail sequencing in portable SSDs, notebook subsystems, and telecom gateway modules where low-loss, fast turn-on (10 µs rise time), and integrated quick output discharge are critical.

For engineers reviewing the DML10M8LDS datasheet, DML10M8LDS pinout, DML10M8LDS application, or DML10M8LDS equivalent, this device is selected for high-current, low-voltage (0.8V–3.5V input) load switching with minimal BOM count, thermal-aware PCB layout guidance, and precise timing behavior across V_BIAS and V_IN combinations.

Technical Context

The DML10M8LDS implements a self-contained load switch architecture with integrated gate driver, bias regulator, and discharge FET-eliminating external components. Its control logic accepts 1.2V minimum high-level enable voltage and supports fixed power sequencing (V_BIAS → V_IN → ON) to guarantee specified t_R ≤ 33 µs and t_ON ≤ 65 µs.

Thermal performance is defined by θ_JA = 60°C/W and θ_JC = 8°C/W, enabling 6A operation at +85°C ambient when mounted on a 4-layer board with exposed pad thermal vias. Input voltage range (0.8V to V_BIAS−1.5V) and R_DS(ON) dependency on V_BIAS–V_IN margin directly impact conduction loss in sub-1.2V core rails.

FAQ

What is the minimum V_BIAS required for reliable operation at 0.8V V_IN?

The datasheet specifies V_BIAS must be ≥3.2V and ≥V_IN + 1.5V. At V_IN = 0.8V, minimum V_BIAS is 2.3V-but the absolute minimum V_BIAS rating is 3.2V. Therefore, 3.2V is the valid minimum, ensuring R_DS(ON) remains ≤10 mΩ and t_R stays within 33 µs at +85°C.

Can the DML10M8LDS safely drive a 10A pulsed load?

Yes-the device supports 9A maximum pulsed current (I_PLS) under 300 µs pulse width and 2% duty cycle conditions. For 10A pulses, thermal limits must be verified: at 9A, power dissipation is ~810 mW (9² × 10 mΩ); sustained 10A exceeds safe junction temperature unless board layout provides exceptional cooling beyond θ_JA = 60°C/W.

Is the EPAD electrically connected to GND or IN internally?

The EPAD is internally connected to Pin 5 (GND), as confirmed by Diodes' V-DFN3030-8 (Type R) mechanical drawings and thermal test data. PCB layout must tie the EPAD pad directly to the signal ground plane-not the power ground-to maintain noise isolation while enabling thermal conduction.

Does the ON pin require a pull-up resistor when driven by an open-drain controller?

Yes-an external pull-up resistor (typically 10–100 kΩ to V_BIAS) is required if the controller uses open-drain or open-collector output. The ON pin has no internal pull-up; leaving it floating violates the "Do not leave floating" directive in the datasheet and may cause erratic switching or shoot-through failure.
