1 General description

PF5030 is a power management integrated circuit (PMIC) designed for S32Z2/E2 processors. Its input voltage of up to 5.25 V maximum makes it ideal to work in conjunction with NXP front system supply families (FS86, FS6x) or any other front supply in the automotive drive train market.

Built-in One-Time Programmable (OTP) memory stores key start-up configurations, drastically reducing external components typically used to set output voltage and sequence of external regulators. Regulator parameters are adjustable through I2C after start-up, offering flexibility for different system states.
