NXP Semiconductors PF51x3 Multi-Channel PMICs
NXP Semiconductors PF51x3 Multi-Channel Power Management Integrated Circuits (PMICs) target automotive safety and industrial applications. The PF51x3 is configurable, making it a great companion and fit for various system-level power requirements. Integrated safety features ensure compliance with the ISO 26262 standard and the ASIL B functional safety level. The PF51x3 is available as a standard non-safety device for applications that do not require ISO 26262 compliance.
The PF51x3 is suitable for applications that require multiple power supplies, including infotainment, ADAS, vision, and radar. It can serve as a companion to another PMIC or SBC, such as an FS8x family member. The PF5113 is suitable for NXP radar system solutions, including S32R41, TEF82xx, and SAF85xx.
