First, autonomous driving and smart cockpits significantly increase power consumption and power usage;
Secondly, various sensors are more sensitive to power supply noise;
Third, the distributed ECUs and domain controllers, along with numerous wiring harnesses, make it easier for noise generated by the power supply circuits to propagate and couple.
EMI Challenges from Automotive Power Chips
1. Autonomous driving and smart cockpits significantly increase power consumption and energy usage;
2. Various sensors are more sensitive to power supply noise;
3. Distributed ECUs and domain controllers, along with numerous wiring harnesses, make it easier for noise generated by the power supply circuitry to propagate and couple.
This also presents significant challenges in actual testing.
1. Conducted high-frequency noise is difficult to suppress;
2. Common-mode current not only causes transmission test failures, but also introduces space-radiated noise;
3. Radiated noise poses a significant challenge to the selection of components and circuit design for PCB layout.
Is it possible to solve the EMI problem of automotive power chips in one go?
That's right! It's the JWQM93902 automotive-grade power module, which meets the latest AECQ-104 standard certification for automotive-grade modules!
