Two Multi-Switch Detection Interface (MSDI) devices that that consume up to 98% less system power than conventional discrete solutions, has been announced by Texas Instruments. The TIC12400 and TIC12400-Q1 are the first switch and sensor monitors that directly interface with resistor-coded switches.
Manufacturers, especially automotive manufacturers, are challenged to integrate more functionality while saving power and space.
The TIC12400 and TIC12400-Q1 can alleviate this challenge by natively monitoring the inputs and decoding the resistor path of as many as 54 switches in one device, offloading the signal decoding task from the processor.
Additionally, by directly monitoring and providing built-in diagnostics for 24 channel inputs, the devices polling sequence architecture reduces the system microcontroller active time, significantly cutting system power usage for applications including automotive body electronics and factory and building automation equipment.
Key features and benefits of the TIC12400-Q1:
Tools and support to speed design
The TIC12400 evaluation module (TIC12400EVM-KIT) enables designers to quickly and easily evaluate the new device’s capabilities.
Designers of automotive body control modules can decrease system cost and vehicle weight by leveraging the new device to create a smarter, more centralised architecture, reducing the number and overall weight of wires going into the harness.
