Multiport USB Type-C Docking System

Texas Instruments recently introduced a multiport USB Type-C and Power Delivery (PD) minidock reference design, which you can power it via a traditional power adapter, USB Type-C adapter, or notebook computer. The reference design—which that provides audio, USB data, power, and video support—offers a fully tested plan for a compact 2” × 4” dock.TI usb type c

A TPS65982 USB Type-C and PD controller sits at the core of the USB Type-C and Power Delivery Minidock. It enables dual-role port USB Type-C functionality, and thus it’s capable of delivering 60 W of power and supporting DisplayPort Alternate Mode and USB data transmission. In addition, the design features the TPS65986 USB Type-C and PD controller, an HD3SS3212 SuperSpeed multiplexer, a TUSB321 dual-role port controller, and an HD3SS460 Alternate Mode multiplexer, which work together to provide dual-role port capability for power, data, and video transfer.

Features, specs, and benefits:

  • Bidirectional power and data transfer
  • Smallest solution size enables you to develop up to 50% percent smaller docking stations compared to similar systems.
  • DisplayPort and High-Definition Multimedia Interface (HDMI) design flexibility
  • Fast development time: All integrated circuits (ICs) within the design are compliant with the current USB Type-C and PD standards, simplifying and speeding engineers’ design cycles.
    Simple implementation

The minidock TI Designs reference design (TIDA-01243) is now available for download. Additionally, an evaluation module allows designers to quickly evaluate and implement their minidock designs. The USB-CTM-MINIDK-EVM costs $499.

Small, Low-Power Battery Management Solution for the IoT

Texas Instruments’s new bq25120 battery management solution features low quiescent current (Iq) at 700-nA with the buck converter and operates at 1.8 V. Supporting batteries from 3.6-V to 4.65-V, and fast charge currents from 5-mA to 300-mA, the bq25120 enables wearables and Internet of Things (IoT) applications to remain on without draining the battery. TI Battery1

The bq25120 includes a linear charger, configurable LDO, buck converter, load switch, push button control, and battery voltage monitor. You can use it with other devices to integrate more end application features.

With the $99 bq25120 evaluation module (EVM), you can speed up time to market by easily evaluating device features and performance. The 2.5 mm × 2.5 mm bq25120 charger costs $1.60 in 1,000-piece quantities.

SWIFT DC/DC Buck Converters Reduce EMI

Texas Instruments recently launched the industry’s first 20-A and 30-A synchronous DC/DC buck converters with frequency synchronization for low-noise and reduced EMI/EMC and a PMBus interface for adaptive voltage scaling (AVS). The SWIFT 20-A TPS544B25 and 30-A TPS544C25 converters integrate MOSFETs and feature small PowerStack QFN packages to drive ASICs in space-constrained and power-dense applications. When used with TI’s WEBENCH online design tools, the converters simplify power conversion and speed the power supply design process. TI Swift

The highly integrated converters feature 0.5% reference-voltage accuracy, as well as full differential remote-voltage sensing. Frequency synchronization to an external clock eliminates beat noise and reduces EMI. Moreover, the TPS544B25 and TPS544C25 offer pin-strapping that enables the devices to start up without PMBus commands to an output voltage set by a single resistor. Programmability, real-time monitoring of the output voltage, current and external temperature, and fault reporting via PMBus simplify power-supply design, increase reliability, and reduce component count and system cost.

Together, the TPS544C25 and UCD90240 provide a complete PMBus point-of-load (POL) and sequencing solution. Download the Complete PMBus Power System for Enterprise Ethernet Switches TI Designs reference design.

TPS544B25 and TPS544C25 key features and benefits:

  • Integrated power MOSFETs support 20-A and 30-A of continuous output current.
  • On-chip PMBus interface and non-volatile memory simplify power-supply design and enable customization. Read a blog post on “PMBus – what is the value anyway?”
  • Voltage-control mode with input feed-forward improves noise margin and responds instantly to input voltage changes.
  • Other features include internal soft start, input under-voltage protection, thermal shutdown and a reset function.

The TPS544B25 costs $4.08 in 1,000-unit quantities. The TPS544C25 is $4.49 in 1,000-unit quantities. Evaluation modules are available.

Static Code Analysis for MSP430 Microcontrollers

IAR Systems, the leading vendor of embedded development tools, is proud to introduce its latest product innovation C-STAT. C-STAT provides powerful static analysis and is now available fully integrated in the high-performance development toolchain IAR Embedded Workbench for Texas Instruments’s (TI) MSP430 MCUs.IAR C-STAT

Important concerns for embedded developers today include adherence to coding standards, as well as increased application complexity that might interfere with code quality. Using a flexible static code analysis tool like C-STAT addresses both these issues by detecting potential code errors in complex applications and by ensuring compliance with coding standards applicable for embedded applications in various segments.

C-STAT is a powerful static analysis tool that executes fast and provides analysis results directly in the IAR Embedded Workbench IDE. It checks compliance with rules as defined by coding standards including MISRA C:2004, MISRA C++:2008 and MISRA C:2012, as well as hundreds of rules based on, for example, the Common Weakness Enumeration (CWE) and CERT C/C++. Users can easily select which rule-set or which individual rules to check the code against. The tool detects potential code errors including for example memory leaks, access violations, arithmetic errors and array and string overruns. By finding such errors early, developers can take full control of their code and lower the risk of breaking the budget and deadline for a project.
