Smart load switch minimizes power losses in automotive applications

October 29, 2026

Integrating numerous protection features and improved efficiency, the Diodes Incorporated DML1012ALDSQ automotive-compliant smart load switch allows reliable power sequencing and control in advanced driver-assistance systems (ADAS) and infotainment.

The DML1012ALDSQ is part of a load switch portfolio designed for power-efficient use in various automotive applications such as ADAS and display clusters. The switch uses an N-channel MOSFET that delivers continuous current up to 6A, and pulsed current up to 9A.

 

Featuring a low on-resistance as well as a quiescent current of just 28µA, the DML1012ALDSQ contributes to the ongoing efficiency improvements seen in electric vehicles and offers a 20µs rise time for rapid response when deployed in automotive power systems.

 

Several key protection features are integrated into the load switch to reduce PCB space, such as quick output discharge to ensure downstream components are fully discharged when a device is shut down, and undervoltage lockout (UVLO) to disable functions if the supply voltage is below a safe operating threshold.

Features

  • V-DFN3030-8 packaging
  • 3.2V to 5.5V bias voltage
  • Input voltage range: 0.8V to 4V

Applications

  • Automotive electronics:
    • ADAS
    • Infotainment platforms
    • Display clusters
