ATIC130 4L B2 – Airbag Control Unit Fault-Prone Driver IC, Replacement for Crash Recording Module

The ATIC130 4L B2 is a dedicated driver IC commonly found in automotive airbag control units.

It is responsible for activating the squib loop and recording crash event data.
Over time, this chip becomes one of the most failure-prone components in the module.
Common failures include internal short circuits, loss of communication, and no response after collision.

If your airbag control unit stores crash data or cannot be cleared, this IC is often the root cause.
This replacement part works for many European and American vehicle models using the same chip layout.

Each unit is properly tested for basic functionality before shipping.
Please confirm your original chip marking matches “ATIC130 4L B2” before purchase.

This chip is ideal for repair shops, automotive electronics restorers, and ECU reconditioners.
It helps restore the airbag module without replacing the entire control unit.
