PF7100 design guidelines Application note
●The PF7100 family of devices feature a power management integrated circuit (PMIC) designed for high performance i.MX 8 processors. It features high-efficiency buck converters and linear regulators for powering the processor, memory and miscellaneous peripherals.
●The PF7100 PMIC family comprises two devices, to address different market needs:
■PF7100 automotive ASIL B device provides a full feature PMIC with five switching regulators and two LDOs, integrates functional safety mechanism to comply with the ISO 26262 standard, and provides a powerful and flexible solution for ASIL B(D) automotive modules.
■PF7100 automotive QM device provides the same switching and LDO regulator resources as ASIL B device, but without the functional safety overhead to provide an economic platform for systems not required to meet the ASIL B qualification.
■The automotive QM device is good to address industrial market as well.
●Built-in one-time programmable (OTP) 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 power-up offering flexibility for different system states.
●The PF7100 devices are available in HVQFN48 package with dimple wettable flank. Refer to PF7100 data sheet for more information.
