PEPS

Automotive PEPS (Passive Entry Passive Start) systems serve as the gateway to modern intelligent vehicles, relying on ultra-low power RF communication between key fob and vehicle receivers. These circuits are highly sensitive to electrostatic discharge (ESD), transient surges and conducted electromagnetic interference (EMI) due to close human interaction and noisy vehicle harness environments. YINT Electronics’ PEPS protection solution integrates ultra-low leakage ESD protection arrays to prevent damage from static events, TVS transient suppressors to clamp unexpected voltage spikes, and Schottky diodes for efficient power stabilization and reverse protection. These multi-layer components ensure accurate signal transmission, long-term reliability and immunity against electrical disturbances in keyless access and passive start systems.
