New Controller IC and Plug-in Power Module Simplify Design and Increase Adoption for Ethernet-Powered Appliances

May 17, 2004 – Texas Instruments Incorporated announced a versatile new integrated circuit (IC) controller and the industry’s first Power-over-Ethernet plug-in power module that reduces design time and eases implementation of Ethernet-powered industrial and commercial devices such as WLAN access points, IP phones, security and point-of-sale systems.

Next-Generation Powered Device Controller
TI’s new TPS2375 controller builds upon the success of the TPS2370, introduced in 2003, to effectively manage discovery, classification and delivery of direct-current (DC) power to a powered device. The IC offers increased flexibility and performance as it manages the interface between the power source equipment (PSE) and a commercial or industrial powered device (PD), while providing necessary power management control and protection.The controller further protects the powered device by implementing a 450-mA operating current limit, thermal shutdown and in-rush current limiting. The device utilizes a tiny external resistor to program in-rush current limit, enabling interoperability between a wide range of IEEE 802.3af-compliant and pre-802.3af”legacy” PSE systems. For additional technical features, and fixed, adjusted or legacy under-voltage lockout versions of the TPS2375, see www.ti.com/sc04104a.

First Complete Power-over-Ethernet Plug-in Module
Realizing time to market is critical, TI also announced the industry’s first, fully IEEE 802.3af-compliant plug-in power module for Ethernet-powered devices. The PTB48540 module significantly reduces time to market for designers of specialized, Ethernet-powered IP phone consoles, security systems, card readers, point-of-sale terminals or other systems that need to quickly detect, classify and deliver up to 10 watts of DC power. Requiring only a small external Power-over-Ethernet isolation transformer, the low-profile module (41 mm x 38 mm x 8.5 mm) provides a complete power solution for powered devices. TI’s TPS2375 controller sits inside the module, as well as an electro-magnetic interference (EMI)/input voltage transient filter, and both data and spare line bridge networks. The module is available in 3.3-V, 5-V or 12-V outputs with through-hole or surface mount device (SMD) mounting options. For more technical information on the PTB48540 plug-in module, see www.ti.com/sc04104b.

Atmel Introduces World’s Most Innovative 2-pin, Self-Powered Serial EEPROM Targeting the IoT, Battery, Consumable and Cable Identification Markets

те4

Atmel Corporation launched the industry’s most innovative Single-Wire EPEROM with only two-pins-a data pin and ground pin for operation-making the new family ideal for the Internet of Things (IoT), wearables, consumable, battery and cable identification markets. The new devices are self-powered, eliminating the need for a power source or Vcc pin, with a parasitic power scheme over the data pin. These devices provide best-in-class ultra-low power standby of 700 nA, 200 µA for write current, and 80µA for read current at 25 degree Celsius-delivering just one-third of the power of leading competitors.

те4With confined spacing in smaller IoT, wearables, battery and cable identification applications, Atmel’s AT21CS01/11 devices eliminate the need for external capacitors and rectifiers with its parasitic power scheme over a single data pin. Additionally, the new devices have an ultra-high write endurance capability to allow more than one million cycles for each memory location to meet the requirements for today’s high-write endurance applications.

The AT21CS01/11 products include a simple product identification with a plug-and-play 64-bit unique serial number in every device, making the device ideal for smart, connected devices in today’s IoT world including wearables such as smart fitness bands and healthcare devices. The devices also deliver industry-leading electrostatic discharge (ESD) rating (IEC 61000-4-2 Level 4 ESD Compliant), so applications such as cables, consumables, etc. can tolerate exposure to the outside environment or direct human contact while still delivering flawless performance.

те5The new devices follow the I2C protocol, allowing for an easy migration from existing EEPROM with less overhead and capability to connect up to eight devices on the same bus. The AT21CS01 devices offer a security register with a 64-bit factory programmed serial number and an extra 16-bytes of user programmable and permanently lockable storage, delivering a guaranteed unique serial number for inventory tracking, asset tagging and can permanently protect the data if needed.

There are two variants of the device available to support different voltage requirements. Atmel’s AT21CS01 is targeted for low-voltage applications operating at 1.7 V – 3.6 V. For applications that require higher voltage ranges such as Li-Ion/polymer batteries, the AT21CS11 will support 2.7 V – 4.5 V operating range and is the ideal product to meet IEEE1725 specifications for electronic identification of battery packs.

Silicon Labs Launches Industry’s Fastest Isolated Current Sense Amplifier

те1

те1Silicon Labs introduced an isolated current sense amplifier delivering robust isolation and the industry’s highest bandwidth and lowest signal delay. Silicon Labs’ new Si8920 isolated amplifier provides an ideal current shunt measurement solution for power control systems operating in harsh environments such as industrial motor drives, solar inverters, high-voltage power converters, uninterruptible power supplies (UPS) and electric/hybrid-electric vehicle (EV/HEV) systems.

Fast, accurate current sensing is essential for all high-power systems and power converters with high-voltage stages. Measuring current on high-voltage rails (up to 1200 V) with a galvanically isolated amplifier provides critical information to the low-voltage controller that improves system response time and efficiency. The Si8920 isolated amplifier provides a differential, low-voltage input scaled for connection to current shunt resistors, enabling the controller to make precise measurements of current on high-voltage rails while maintaining best-in-class electrical isolation. The Si8920 device’s industry-leading signal bandwidth (up to 750 kHz) ensures rapid, precise dc current measurement and accurate representation of the primary signal and harmonics.

те2The Si8920 isolated amplifier uses Silicon Labs’ proven, CMOS-based isolation technology, which meets stringent UL, VDE, CQC and CSA standards, supports up to 5 kV withstand and 1200 V working voltage, and offers a wider operating temperature range, better noise immunity and longer lifetimes than competing isolation technologies. The Si8920 amplifier’s exceptionally low 1 µV/°C offset drift ensures stable performance over diverse operating conditions.

The Si8920 provides a robust, reliable isolated amplifier solution that meets the product longevity requirements of industrial automation, green energy and Internet infrastructure equipment. Many power systems feature long lifetime warranties and are expected to operate for 25 years or more in the field. Isolation often can be a point of first failure and a lifetime-limiting device in many power systems. Traditional isolators, based on optocoupler technology, suffer from limited temperature range and can degrade with the external environment.те3 In contrast, CMOS-based isolation components such as the Si8920 isolated amplifier operate over a full industrial temperature range and can support product lifetimes of up to 100 years.

The Si8920 isolated amplifier provides very fast response time with an unparalleled 0.75 µs signal delay across the isolation barrier, allowing power control systems to react rapidly to transient load conditions. Ultra-low signal delay enables control loops to respond quickly, resulting in a more efficient and stable system as the controller can take action sooner to maintain the desired performance. Low signal delay also enables the power system to make quick corrective responses to unusual, potentially dangerous events, which helps reduce equipment repair and maintenance costs.
