145 / 205 page  NXP Semiconductors PF09 Nine-channel power management IC with advanced system safety monitoring 14 Functional safety The PF09 is developed in accordance with the ISO 26262 standard and in compliance with the industrial IEC61508 safety standard as a safety element out of context (SEooC). It provides a comprehensive set of functional safety features to reach an automotive safety integrity level up to ASIL D and industrial SIL 2. The available safety monitoring features depend on the target safety integrity level and PF09 device version. A superset of the potential safety functions are listed below: • Output voltage monitoring with dedicated bandgap reference • Bandgap monitoring • Protected I2C protocol with CRC verification. • Hash fault monitoring (dynamic CRC) • System watchdog management • Dedicated Fail-safe output (FS0B) • System interface safety outputs (RSTB, PGOOD, INTB) • External fault detection inputs (FCCU, ERRMON) • Power-up analog self-test + ABIST on demand • Power-up logic built-in self-test + LBIST on demand • Fully isolated digital machine supervisor Main digital controller aaa-056080 Clock monitoring VIN_OV monitor OV monitoring ABIST BG MON Monitoring BG Analog supply Digital supply Clock management Regulator BG Safety outputs AMUX Thermal monitoring FCCU mon ERRMON XRESET FCCU1/2 MCU I2C comm.
