DALLAS, Oct. 10, 2017 /PRNewswire/ — Texas Instruments (TI) (NASDAQ: TXN) today introduced two multi-switch detection interface (MSDI) devices that consume up to 98 percent less system power than conventional discrete solutions. The TIC12400 and TIC12400-Q1 are the first switch and sensor monitors that directly interface with resistor-coded switches. For more information, see www.ti.com/TIC12400Q1-pr.
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. It is available from the TI store for US$199.00.
Designers of automotive body control modules can decrease system cost and vehicle weight by leveraging the new device to create a smarter, more centralized architecture, reducing the number and overall weight of wires going into the harness. Explore how the TIC12400-Q1 can decode high-voltage switch inputs in the Automotive Multi-Switch Interface Reference Design.
Package, availability and pricing
The TIC12400-Q1, TIC12400 and TIC10024-Q1 are available in volume today through the TI store and authorized distributors. System designers who don’t require high-volume input monitoring can select the TIC10024-Q1 to simplify the configuration for managing digital-only inputs. All three devices come in a 9.7-mm-by-4.4-mm thin-shrink small outline package (TSSOP). Features and pricing are listed in the following table:
