Collision signal interface
The open collector driver raises or lowers the voltage of the pin no. 58 by switching on and off the drive
transistor. The vehicle module can be operated normally only by the logic of open collector interface
and can be maintained in a pull-up state. The followings are the specifications of the electrical interface.
Pin No.
Driving current (current value
when the transistor is turned
on)
Leakage current (current value
when the transistor is turned
off)
Load resistance
The load resistance of the SDM is 590 ohms or higher. It may not be possible to operate the collision
occurrence circuit normally if the resistance value is not as specified.
