NXP AN14910 PF09 PMIC Hardware Design Guidelines
Hardware design guidelines for the NXP PF09 PMIC optimized for i.MX95 processors, covering external components, EMC optimization, and functional safety compliance.
Overview
This application note provides comprehensive hardware design and layout guidelines for the NXP PF09 Power Management Integrated Circuit (PMIC), which is optimized for high-performance i.MX95-based applications. The document details the device's architecture, including five high-efficiency buck converters with output currents up to 3.5 A and four linear regulators. It provides specific recommendations for AEC-Q automotive-grade external components, including inductors and X7R ceramic capacitors for SMPS and LDO supplies. The guide outlines functional safety features required for ISO 26262 ASIL-D and IEC 61508 SIL-2 compliance, such as built-in self-tests (ABIST/LBIST), fail-safe outputs (FS0B), and thermal monitoring. Additionally, it covers EMC optimization techniques including frequency spread spectrum and manual tuning.
Use Cases
- Automotive infotainment systems
- Connectivity domain controllers
