PF8201

PF8101; PF8201 9-channel power management integrated circuit for high performance applications Rev. 4 — 24 February 2021 Product data sheet 1 Overview The PF8101/PF8201 is a power management integrated circuit (PMIC) designed for high performance i.MX 8 based applications. It features five high efficiency buck converters and three 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 five high efficiency buck converters Three 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 PF8101; PF8201 9-channel power management integrated circuit for high performance applications 3 Simplified application diagram PF8101 / PF8201 VSNVS BUCK1 VIN: 2.7 V to 5.5 V BUCK2 BUCK5 BUCK6 BUCK7 VDD_SNVS VDD_MAIN VDD_GPU VDD_CPU(A35) VDD_DDRIO 1.8 V I/O (LV GPIO) 3.3 V I/O (HV GPIO) MCU LDO1 LDO2 LDO3 VDD_SCU SDCARD0 2.5 V l/O CONTROL SIGNALS INTERFACING AND I2C COMMUNICATIONS LPDDR Memory I2C D...
