PMICs for High-Performance Processing Applications
June 06, 2019 by Paul Shepard
The PF8100/PF8200 PMIC family from NXP Semiconductor is designed for high-performance processing applications such as infotainment, telematics, clusters, vehicle networking, ADAS, vision and sensor fusion. Two versions are available to address different market needs:
- The PF8200 with functional safety to comply with the ISO 26262 standard, provides a powerful and flexible solution for ASIL-B (D) automotive applications.
- The PF8100 is the basic version of this product, with power management and digital control without the functional safety features for systems not requiring ASIL-B compliance.
This family is designed for i.MX 8, i.MX 8X and S32V processors' based applications and suitable for powering Layerscape LS1043A and other high-performance processors. It offers seven high-efficiency buck converters and four linear regulators to power the processor, memory and miscellaneous peripherals.
