Product short data sheet

1 General description

The FS86 device family, which is SW compatible with the FS84/85 family, expands the

power capability, the safety integration and the system scalability of domain controller

applications to address the multiple MCU requirements present in ADAS, radar and

electrification applications.

The FS86 includes multiple switch mode and linear voltage regulators, and enhanced

safety features with fail-safe outputs. The latest NXP HV buck architecture features

a 15 A capability with e-fuse protection to shut down the system power, to prevent

any damage in case of a harmful event. The ability to monitor ten voltages with

+/-1% accuracy extends the system safety concept by allowing QM rails from others

components to be monitored.

With its innovative synchronization feature, the FS86 is part of the BYLink system

power platform, enabling a new smart approach to designing safe system power

management. It provides power, safety and system scalability to ease platform

development strategies. Cascaded system SBC/PMICs behave as ONE with safety and

sequencing synchronization.

The FS86 is part of a complete family of devices that offer scalability in power and safety,

and provide pin-to-pin and software compatibility. It is developed in compliance with the

ISO 26262 standard and is qualified according to AEC-Q100 requirements.
