PF5023

Roll over image to zoom in

The PF5023 is NXP’s multi-channel PMIC device designed to be used for high performance automotive and industrial applications. The PF5023 is also highly configurable making it a perfect companion and fit for various system level power requirements.

Integrated and independent voltage monitoring circuits ensure compliance with ISO 26262 standard and functional safety up to ASIL B level. The PF5023 is also available as a standard non-safety device for applications that don’t require the ISO compliance.

The PF5023 is suitable for a variety of applications including infotainment, ADAS, vision, and RADAR either as a standalone power solution or also as a companion to another NXP PMIC like the PF8200 or an SBC like the FS8500.

This device is suitable for i.MX and S32 processors based applications.

Programmability

Supplies, sequencing, and specific functions can be programmed by One Time programmable (OTP) memory
During development phase, Customized OTP part can be programmed using the KITPF502XSKTEVM board
Custom OTP can be provided for production. Please contact your NXP sales channel (NXP or your distributor)
Standard Predefined OTP supporting popular MCUs or SoCs may be be found in data sheet “ordering information” chapter
Custom OTP can be created using the PF5023 OTP tool integrated in the NXP GUI software tool
