Diodes Incorporated DML3008LFDS-7

Overview

DML3008LFDS from Diodes Incorporated is a single-channel smart load switch integrating an N-channel MOSFET with 9–12.5 mΩ on-resistance, 0.5–20 V input voltage range, and active-high enable control. It delivers power domain switching with integrated power-good signaling, thermal shutdown, and load-bleed functionality for hot-swap and portable power management systems.

For engineers reviewing the DML3008LFDS datasheet, DML3008LFDS pinout, DML3008LFDS application, or DML3008LFDS equivalent, key selection criteria include ultra-low R_ON, controlled slew rate (17–43 kV/s), <1 µA standby current, PG open-drain timing (0.35–0.6 ms turn-on), and V-DFN2020-8 package compatibility in space-constrained designs.

Technical Context

The device implements a charge-pump-based gate driver to fully enhance the internal N-MOSFET across its full 0.5–20 V input range while maintaining low quiescent current. Its thermal shutdown circuit activates at +145°C with +20°C hysteresis and disables only when EN is inactive.

Power Good (PG) is an open-drain output synchronized to MOSFET gate charge completion-not output voltage regulation-enabling precise sequencing of downstream rails. The BLEED pin integrates a 70–150 Ω discharge path tied externally to VOUT, enabling rapid load discharge without discrete components.

FAQ

What is the maximum continuous current rating for DML3008LFDS?

The DML3008LFDS is rated for 10.5 A maximum continuous current under specified thermal conditions (θ_JA = 40°C/W, T_A = +85°C). Actual current capability depends on PCB copper area, via count under the exposed pad, and ambient temperature. Derating curves in the datasheet show 8.2 A at +100°C ambient with standard 2-layer board layout.

Can the PG pin be left floating if not used?

No-the PG pin must not be left floating. As an open-drain output, it requires either an external pull-up resistor (≥1 kΩ) to a valid logic-high voltage or a direct connection to GND if unused. Leaving it unconnected risks undefined logic states, noise coupling, and potential interference with adjacent signals on dense PCBs.

How does the internal bleed resistor interact with external RBLEED?

The internal bleed resistor (70–150 Ω) connects between BLEED and GND. When an external resistor R_EXT is placed between BLEED and VOUT, the total discharge path becomes R_INT + R_EXT. Since R_INT is fixed, R_EXT adds series resistance to limit peak discharge current and power dissipation-critical when discharging large output capacitances (>100 µF).

Is DML3008LFDS qualified for automotive applications?

No-DML3008LFDS is not AEC-Q100 qualified. It is specified for industrial (-40°C to +85°C) and commercial applications. Diodes offers automotive-grade variants (e.g., DML3008LFDS-AQ) with PPAP documentation, IATF 16949 manufacturing, and extended temperature validation; contact Diodes sales for qualification details and part numbering.
