The flexibility of an Intelligent Power Switch (IPS) designed in HV-CMOS technology for incandescent lamp in automotive scenarios has been evaluated for the driving of a LED in presence of wiring parasitics. The paper presents how it is possible, through proper reconfiguration of the flexible IPS, to reduce the undesired ringing phenomenon when driving a LED with wiring parasitics thus reducing Electromagnetic Interferences (EMI) and spikes on supply voltage. Electrical simulation and experimental measurements prove the effectiveness of the proposed IPS

Abstract
The flexibility of an Intelligent Power Switch (IPS) designed in HV-CMOS technology for incandescent lamp in automotive scenarios has been evaluated for the driving of a LED in presence of wiring parasitics. The paper presents how it is possible, through proper reconfiguration of the flexible IPS, to reduce the undesired ringing phenomenon when driving a LED with wiring parasitics thus reducing Electromagnetic Interferences (EMI) and spikes on supply voltage. Electrical simulation and experimental measurements prove the effectiveness of the proposed IPSFile in questo prodotto:
