Diodes Incorporated DML10M8LDS-13

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 electronics, SSDs, and telecom infrastructure with integrated quick output discharge.

For engineers reviewing the DML10M8LDS datasheet, DML10M8LDS pinout, DML10M8LDS application, or DML10M8LDS equivalent, key selection criteria include input voltage compatibility (0.8V to V_BIAS−1.5V), thermal resistance (θ_JA = 60°C/W), quiescent current (35 µA), turn-on rise time (10 µs), and V-DFN3030-8 (Type R) package footprint constraints.

Technical Context

The DML10M8LDS implements a bias-supplied control architecture where V_BIAS powers internal logic and gate driver, enabling operation with VIN as low as 0.8V while maintaining robust switching performance. Its integrated discharge FET actively pulls OUT to GND when disabled, eliminating external RC networks.

Power sequencing sensitivity is defined by two recommended startup orders: V_BIAS → VIN → ON, or VIN → V_BIAS → ON. Deviation causes variation in t_D-ON, confirming tight coupling between bias rail stability and switching timing accuracy.

FAQ

What is the minimum recommended input voltage for reliable operation?

The DML10M8LDS supports VIN as low as 0.8V when V_BIAS ≥ 2.3V, but stable operation requires VIN ≤ V_BIAS − 1.5V. At V_BIAS = 3.2V, minimum functional VIN is 1.7V; below that, R_DS(ON) increases significantly and may exceed 15 mΩ, raising conduction losses.

Can the device operate without an external input capacitor?

No. A minimum 10 µF ceramic capacitor is required close to the IN pins to suppress voltage dip during 6A inrush. Without it, VIN can sag below operational threshold during turn-on, causing erratic behavior or latch-up. Layout guidelines specify placement within 2 mm of pins 1/2.

Is the EPAD electrically connected to any internal node?

Yes-the exposed pad (EPAD) is internally connected to the IN terminal and must be soldered to a PCB copper pour tied to the IN net. This provides both thermal dissipation (θ_JC = 8°C/W) and low-inductance power path; floating or grounding the EPAD degrades thermal performance and may cause instability.

Does the ON pin require a pull-up resistor?

No. The ON pin has internal logic-level compatibility and accepts direct connection to MCU GPIO. However, it must never be left floating-uncontrolled states risk partial turn-on and excessive heating. A 100 kΩ pull-down is recommended if driven by open-drain sources.
