Automotive Solutions

Electronic components meeting quality specifications established by the Automotive Electronics Council (AEC) are suitable for automotive use without additional component-level qualification testing. Most commonly referenced AEC documents include:

  • AEC-Q100 - Failure Mechanism Based Stress Test Qualification For Integrated Circuits
  • AEC-Q101 - Failure Mechanism Based Stress Test Qualification For Discrete Semiconductors

Automotive Safety Integrity Level (ASIL) is a risk classification scheme defined by the ISO 26262 - Functional Safety for Road Vehicles standard. This is an adaptation of the Safety Integrity Level (SIL) used in IEC 61508 for the automotive industry. ASIL certified devices enable implementation of ASIL traction inverter designs, dramatically reducing development time and cost.

Power Integrations offers a wide range of automotive qualified devices:

InnoSwitch3-AQ Flyback Switcher ICs

The InnoSwitch3-AQ Family of switcher ICs dramatically simplifies the design and manufacture of flyback power converters, particularly those requiring high efficiency and compact size.

Qspeed Diodes

Qspeed diodes have the lowest QRR of any Silicon diode. Their recovery characteristics increase efficiency, reduce EMI and eliminate snubbers. These features help designers improve the performance of their power conversion circuits.
