Power and Safety Scalability Offered By The Advanced NXP PF81/PF82 PMICs

Submitted By: 

Shreepanjali Mod
The PF8100/PF8200 PMIC family specifically caters the requirements of high-performing processing applications like sensor fusion, vision fusion, ADAS, vehicle networking, clusters, telematics, infotainment, etc. These are being offered in two version that take care of different market needs:
 
The PF8100 is the fundamental version of this products with digital control and power management without any functional safety features for systems not needing ASIL-B compliance. 
 
The PF8200 comes loaded with functional safety that complies with ISO 26262 standard and offers a flexible and powerful solution for ASIL-B (D) automotive applications.
