DML30x Smart Load Switches

Diodes' DML30xx smart load switch portfolio expands to include DML3012LDC (15 A), DML3011ALFDS (10.5 A), DML3010ALFDS (10.5 A), and DML3008LFDS (10.5 A). These compact devices offer high-current power domain switching for 0.5 V to 20 V. They efficiently manage power delivery to microcontrollers, graphics cards, ASICs, FPGAs, and storage for applications including servers, computing hardware, industrial equipment, hot-swap devices, and peripheral ports.

Featuring a chip-on-chip design with an ultra-low R_ON N-channel power MOSFET, the DML30x switches provide high power density within an ultra-compact footprint. The underside heat pad enhances thermal efficiency, ensuring reliable operation. Power consumption is minimized with a typical on-state current of less than 150 μA and 0.1 μA in standby mode.

These load switches integrate multiple functions, reducing additional circuitry, PCB area, and time to market. A comprehensive choice of safeguards and monitoring features include short-circuit protection, overcurrent protection, undervoltage lockout, and soft start. Quick discharge capabilities and thermal shutdown protection further enhance reliability. The DML3008LFDS, DML3010ALFDS, and DML3011ALFDS are available in V-DFN2020-8 (2 mm x 2 mm) packages, and the DML3012LDC is available in the V-DFN3030-12 (3 mm x 3 mm) package. These smart load switches offer high-current power domain switching control for various voltage rails.
