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


    --  98 percent lower system power: Designers can reduce system power
        consumption from milliamps to microamps in applications that need high
        efficiency. On-device monitoring allows the microcontroller to go into a
        low-power sleep mode and use less power when idle, which is essential
        for applications like automotive start/stop or when a car is parked for
        extended periods of time.
    --  Reduced complexity in a 60 percent smaller footprint: Eliminating up to
        120 discrete components, the TIC12400-Q1 features an input-sharing and
        matrix mode that helps monitor 54 switches and sensors. The highly
        integrated device also includes adjustable wetting currents, timing
        controls, thresholds and built-in redundant circuitry for protection,
        which increases system-level reliability by reducing potential points of
        failure.
    --  Robust, reliable system protection with simplified board layout:
        Integrated electrostatic discharge (ESD) protection and self-diagnostic
        features reduce external protection components. The new devices meet
        International Organization for Standardization (ISO) 10605 ±8-kV ESD
        protection requirements, preventing potential fault events from damaging
        internal circuitry. The fully configurable devices independently monitor
        and protect 24 inputs, providing more headroom for the host
        microcontroller to perform other functions.

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.

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:
