The ADIN1200 is a low power, single-port, 10 Mbps and 100 Mbps Ethernet transceiver with low latency specifications designedfor industrial Ethernet applications.This design integrates an energy efficient Ethernet (EEE) physical layer device (PHY) core with all associated common analog circuitry, input and output clock buffering, management interface and subsystem registers, and media access control (MAC) interface and control logic to manage the reset, clock control and pin configuration.The ADIN1200 is available in a 5 mm ? 5 mm, 32-lead leadframe chip scale package (LFCSP) and can operate with a single3.3 V supply, assuming the use of a 3.3 V MAC interface supply.For maximum flexibility in system level design, a separate VDDIOsupply enables the management data input/output (MDIO) andMAC interface supply voltages to be configured independentlyof the other circuitry on the ADIN1200 allowing operation at1.8 V, 2.5 V, or 3.3 V. At power-up, the ADIN1200 is held inhardware reset until each of the supplies has crossed its minimumrising threshold value and the power is considered good. Brownoutprotection is provided by monitoring the supplies to detect ifone or more of them drops below a minimum falling thresholdand holding the device in hardware reset until the power suppliesreturn and satisfy the power-on-reset (POR) circuit.The MII management interface (also referred to as MDIOinterface) provides a 2-wire serial interface between a hostprocessor or MAC and the ADIN1200, allowing access tocontrol and status information in the PHY core managementregisters. The interface is compatible with both IEEE? 802.3?Standard Clause 22 and Clause 45 management framestructures.The ADIN1200 can support cable lengths up to 180 meters.Note that throughout this data sheet, multifunction pins, such as XTAL_I/CLK_IN/REF_CLK, are referred to either by the entire pin name or by a single function of the pin, for example, XTAL_I, when only that function is relevant.Applications Industrial automation Process control Factory automation Robotics and motion Control Building automation Test and Measurement Industrial internet of things (IoT)

The?ADP1047?/ ADP1048 are digital power factor correction (PFC) controllers that provide accurate input power metering capability and inrush current control for ac/dc systems. The ADP1047 is designed for single phase PFC applications; the ADP1048 is designed especially for interleaved and bridgeless PFC applications.The digital PFC function is based on a conventional boost PFC with multiplication of the output voltage feedback combined with the input current and voltage to provide optimum harmonic correction and power factor for ac/dc systems. All signals are converted into the digital domain to provide maximum flexibility; all key parameters can be reported and adjusted via the PMBus? interface. The ADP1047 / ADP1048 allow users to optimize system performance, maximize efficiency across the load range, and reduce design time to market.The ADP1047 / ADP1048 provide accurate rms measurement of input voltage, current, and power.

The AD7992 is a 12-bit, low power, successive approximation ADC with an I2 C-compatible interface. The part operates from a single 2.7 V to 5.5 V power supply and features a 2 ?s conversion time. The part contains a 2-channel multiplexer and track-and-hold amplifier that can handle input frequencies up to 11 MHz. The AD7992 provides a 2-wire serial interface compatible with I2C interfaces. The part comes in two versions, the AD7992-0 and the AD7992-1, and each version allows for at least two different I2C addresses. The AD7992-0 supports standard and fast I2C interface modes, and the AD7992-1 supports standard, fast, and high speed I2C interface modes. The AD7992 normally remains in a shutdown state while not converting, and powers up only for conversions. The conversion process can be controlled using the CONVST pin, by a command mode where conversions occur across I2C write operations, or an automatic conversion interval mode selected through software control. The AD7992 requires an external reference in the range of 1.2 V to VDD. This allows the widest dynamic input range to the ADC. On-chip limit registers can be programmed with high and low limits for the conversion result, and an open-drain, out-of-range indicator output (ALERT) becomes active when the conversion result violates the programmed high or low limits. This output can be used as an interrupt.PRODUCT HIGHLIGHTS 2 ?s conversion time and low power consumption. I2C-compatible serial interface with pin-selectable addresses. Two AD7992 versions allow five AD7992 devices to be connected to the same serial bus. The part features automatic shutdown while not converting to maximize power efficiency. Current consumption is 1 ?A max when in shutdown mode at 3 V. Reference can be driven up to the power supply. Out-of-range indicator that can be software disabled or enabled. One-shot and automatic conversion rates. Registers store minimum and maximum conversion results.

The LTC2952 is a power management device that features three main functions: pushbutton on/off control of system power, ideal diode PowerPath? controllers and system monitoring. The LTC2952?s pushbutton input, which provides on/off control of system power, has independently adjustable ON and OFF debounce times. A simple microprocessor interface involving an interrupt signal allows for proper system housekeeping prior to power-down. The ideal diode PowerPath controllers provide automatic low loss switchover between two DC sources by regulating two external P-channel MOSFETs to have a small 20mV forward drop. High reliability systems may utilize the LTC2952?s monitoring features to ensure system integrity. These features include: power-fail, voltage monitoring and ?P watchdog. The LTC2952 operates over a wide operating voltage range to accommodate a large variety of input power supplies. The part?s combination of low 20mV external MOSFET regulation and very low standby current matches battery powered and power conscious application requirements.Applications Desktop and Notebook Computers Portable Instrumentations Cell Phones, PDA and Handheld Computers Servers and Computer Peripherals Battery Backup Systems
