CA0013BM BUS Driver / Receiver for Car

1. Device description
CA0013BM is a BUS driver/receiver IC for cars. The IC enables data
communications by connecting an operation panel and components with bus cables.
For logic input, the IC supports both 3.3V and 5V microcomputer outputs.
The output is open collector, and can be connected to either 3.3V or 5V microcomputer input by adding
pull-up resistor.
BUS terminal is durable against failure by electric surge.
This IC is Lead free.

2. Functions and features●Data signal input ：Two-input OR logic（H: Driver ON, L: Driver off）
●Data signal output ：One-output (H: Voltage between BUS+ and BUS- ≧ 110m V,
L: Voltage between BUS+ and BUS- ≦ 30m V)●Maximum number of bus connections ： 20
※ Maximum capacity between bus lines (BUS+ and BUS-): C=8000pF.
※ Be sure to insert a resistance of 60Ωbetween the bus lines before using.
●Because the leak current between BUS+ and BUS- is small (not over 1A) when power is turned off, it
doesn’t interfere with communications of other systems.
●Wide operating voltage range in the receiver mode: 0 to 4.5V.
●Built-in standby function ： Low consumption current in standby mode（Not over 1A）
(H: Standby OFF, L: standby ON)●Built-in output protection circuit ： Operative when voltage between BUS+ and BUS- ≧9V.
●Supply voltage ：+5V single power supply●Package ：8pin SOP
