Overview
The MC33789 is a mixed signal IC for airbag safety applications. The MC33789 is a
SafeAssure functional safety solution. The MC33789 provides a cost effective and flexible
system IC solution across the range of airbag partitions used in cars and other vehicles.
The MC33789 connects to the 12 V vehicle battery and supplies the multiple voltages of a
typical airbag system. The MC33789 can detect switched input states, communicate with both
local and remote crash sensors. It offers an industry standard interface (SPI) and four PSI5
master interfaces. The MC33789 has a dedicated safing state machine that complements
the airbag’s MCU hardware/software safing approach. Also included are a diagnostic - self
protection capability and a programmable analog interface accessible by the system MCU.
