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
