Key Points
• Functional safety in automotive motor control
systems prevents catastrophic failures like
unintended acceleration or braking.
• Designers must implement safety mechanisms
to monitor system parameters like sensor
inputs, safely discharge energy during
crashes, and account for human errors
during maintenance.
• Fail-safe modes, such as three-phase open
state, short fail, and zero-torque control, help
motor control systems transition to safe states
during faults.
• NXP supports functional safety with advanced
MCUs, comprehensive safety documentation,
model-based design tools, and robust safety
mechanisms in power management ICs.
