Multi-Channel (5) PMIC for Automotive Applications: 3 LVBUCK and 2 LDO, Fit for ASIL B Safety Level
The PF51x3 is a multi-channel power management integrated circuit (PMIC) designed for automotive safety and industrial applications. The PF51x3 provides a configurable power management solution for systems requiring multiple power rails, including infotainment, ADAS, vision, and radar applications.
Integrated safety features support ISO 26262 compliance up to ASIL B, while a non-safety variant is available for applications that do not require functional safety. The PF51x3 can be used alongside PMICs or SBCs such as the FS8x family and is suitable for NXP radar solutions including S32R41, TEF82xx, and SAF85xx devices.
