PF8100

PF8100; PF8200 12-channel power management integrated circuit for high performance applications Rev. 11 — 24 February 2021 Product data sheet 1 Overview The PF8100/PF8200 is a power management integrated circuit (PMIC) designed for high performance i.MX 8 and S32x based applications. It features seven high efficiency buck converters and four linear regulators for powering 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. 2 Features Up to seven high efficiency buck converters Four linear regulators with load switch options RTC supply and coin cell charger Watchdog timer/monitor Monitoring circuit to fit ASIL B safety level One time programmable device configuration 3.4 MHz I2C communication interface 56-pin 8 x 8 QFN package NXP Semiconductors PF8100; PF8200 12-channel power management integrated circuit for high performance applications 3 Simplified application diagram VIN: 2.7 V to 5.5 V PF8x00 VSNVS VDD_SNVS IMX8QXP BUCK1 BUCK2 VDD_MAIN VDD_MEMC BUCK3 VDD_GPU BUCK4 VDD_CPU (A35) BUCK5 VDD_DDRIO BUCK6 BUCK7 1.8 V I/O (LV GPIO) 3.3 V I/O (HV GPIO) LDO1 VDD_SCU LDO2 SDCARD0 LDO3 2.5 V I/O LDO4 CONTROL SIGNALS MISC INTERFA...
