NXP Semiconductors PF5030 Fail-Safe System Basis Chip PMICs

NXP Semiconductor PF5030 Fail-Safe System Basis Chip PMICs with multiple switch-mode power supplies (SMPSs) and low-dropout regulators (LDOs) are designed for S32Z2/E2 processors. A maximum input voltage of up to 5.25V makes the PF5030 PMICs ideal for working 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 that drastically reduce external components typically used to set external regulators’ output voltage and sequence. Regulator parameters are adjustable through the I²C after start-up, offering flexibility for different system states.
