NXP Semiconductors PF8100 & PF8200 Power Management ICs

NXP Semiconductors PF8100 and PF8200 Power Management ICs (PMICs) are designed for high-performance i.MX 8, i.MX 8X, and S32V-based applications. The PF8100 and PF8200 PMICs feature seven high-efficiency buck converters and four linear regulators, providing power for the processor, memory, and miscellaneous peripherals. Built-in one-time programmable memory stores key startup configurations, drastically reducing external components typically used to set output voltage and sequence of external regulators. Regulator parameters are adjustable through high-speed I²C after start-up, offering flexibility for different system states.

The PF8200 PMICs feature an integrated Functional safety mechanism to comply with the ISO26262 standard and provide a powerful and flexible solution for ASIL-B(D) automotive modules.

The PF8100 PMICs are the Non-Safety version of this product, providing all the power management and digital control included in PF8200 without the Functional safety overhead to prove a more economical platform for systems not requiring meeting the ASIL-B qualification.

Both NXP Semiconductors Series offer Automotive or Industrial qualifications. The PF8100 and PF8200 PMICs are offered in a compact 8mm x 8mm 56-pin HVQFN (Quad Flat-pack No-leads) package with wettable flanks.
