NXP Semiconductors PF09 9-Channel Power Management ICs

NXP Semiconductors PF09 9-Channel Power Management Integrated Circuits (PMICs) are optimized for high performance i.MX9x-based applications. The NXP PF09 PMICs integrate multiple high-efficiency switch-mode and linear voltage regulators to support base system power from a pre-regulated system rail (3.3V to 5.0V). These devices provide low quiescent current in STANDBY (STBY) and low-power Off modes. Built-in multi-time-programmable configuration, the PF09 PMICs store key startup configurations, drastically reducing the number of external components typically used to set the output voltage and the sequence of external regulators. Regulator parameters can be adjusted via high-speed I2C communication after startup, providing flexibility across different system states.

The NXP PF09 PMICs are developed in compliance with ISO 26262, including safety features such as fail-safe outputs and integrated self-test mechanisms, and are part of safety-oriented system partitioning. These safety features achieve high-integrity safety levels up to ASIL D and comply with IEC 61508, the industrial safety specification, targeting high safety integrity levels up to SIL 2.
