Analog Devices

TheADM2861E, ADM2863E,ADM2865E, andADM2867Eare 5.7 kV rms signal and power isolated RS-485 transceivers. These devices are designed for balanced transmission lines and comply with ANSI/TIA/EIA-485-A-98 and ISO 8482:1987(E). The devices pass radiated emissions testing to the EN 55032 Class B standard with margin on a 2-layer printed circuit board (PCB) using two small external 0402 ferrites on isolated power and ground pins. The device features an integrated, low electromagnetic interference (EMI), isolated dc-to-dc converter, which eliminates the need for an external isolated power supply. The isolation barrier provides immunity to system level electromagnetic compatibility (EMC) standards. The family of isolator devices features ±12 kV contact and ±15 kV air IEC61000-4-2 ESD protection on the RS-485 A, B, Y, and Z pins. The devices also features cable invert pins, allowing the user to quickly correct reversed cable connection on the A, B, Y, and Z bus pins while maintaining full receiver fail-safe performance.Slew rate limited versions are available, which are optimized for low speed over long cable runs, and have a maximum data rate of 500 kbps. Half duplex and full duplex variants are available. The full duplex generics allow independent cable inversion of the driver and receiver for additional flexibility.ApplicationsHeating, ventilation, and air conditioning (HVAC) networksIndustrial field busesBuilding automationUtility networksEnergy meters

The ADM2914 is a quad voltage supervisory IC ideally suited for monitoring multiple rails in a wide range of applications.Each monitored rail has two dedicated input pins, VHx and VLx, which allow each rail to be monitored for both overvoltage (OV) and undervoltage (UV) conditions. A common active low undervoltage (UV) and overvoltage (OV) pin is shared by each of the monitored voltage rails.The ADM2914 includes a 1 V buffered reference output, REF, that acts as an offset when monitoring a negative voltage. The three-state SEL pin determines the polarity of the third and fourth inputs, that is, it configures the device to monitor positive or negative supplies.The device incorporates an internal shunt regulator that enables the device to be used in higher voltage systems. This feature requires a resistor to be placed between the main supply rail and the VCCpin to limit the current flow into the VCCpin to no greater than 10 mA. The ADM2914 uses the internal shunt regulator to regulate VCCif the supply line exceeds the absolute maximum ratings.The ADM2914 is available in two models. The ADM2914-1 offers a latching overvoltage output that can be cleared by toggling theLATCHinput pin. The ADM2914-2 has a disable pin that can override and disable both theOVandUVoutput signals.The ADM2914 is available in a 16-lead QSOP package. The device operates over the extended temperature range of −40°C to +125°C.ApplicationsServer supply monitoringFPGA/DSP core and I/O voltage monitoringTelecommunications equipmentMedical equipment

The ADM3050E is a 5.7 kV rms isolated controller area network (CAN) physical layer transceiver with a high performance, basic feature set. The ADM3050E fully meets the CAN flexible data rate (CAN FD) ISO 11898-2:2016 requirements and is further capable of supporting data rates as high as 12 Mbps.The device employs Analog Devices, Inc.,iCoupler®technology to combine a 2-channel isolator and a CAN transceiver into a single small outline integrated circuit (SOIC) surface-mount package. The ADM3050E is a fully isolated solution for CAN and CAN FD applications. The ADM3050E provides isolation between the CAN controller and physical layer bus. Safety and regulatory approvals (pending) for a 5.7 kV rms withstand voltage, an 849 VPEAKworking voltage, and a 12.8 kV surge test, ensure that the ADM3050E meets application isolation requirements.Low loop propagation delays and the extended common-mode range of ±25 V support robust communication on longer bus cables. Dominant timeout functionality protects against bus lock up in a fault condition, and current limiting and thermal shutdown features protect against output short circuits. The CAN bus input and output pins are protected to ±40 V against accidental connection to a +24 V bus supply. The device is fully specified over the −40°C to +125°C industrial temperature range.ApplicationsCANOpen, DeviceNet, and other CAN bus implementationsIndustrial automationProcess control and building controlTransport and infrastructure

The ADM3055E/ADM3057E are 5 kV rms and 3 kV rms isolated controller area network (CAN) physical layer transceivers with integrated isolated dc-to-dc converters. The ADM3055E/ADM3057E meet flexible data rate (CAN FD) requirements for operation to 5 Mbps and higher and comply with the ISO 11898-2: 2016 standard. The ADM3055E/ADM3057E are capable of supporting data rates as high as 12 Mbps.The devices employ Analog Devices, Inc.,iCoupler®technology to combine a 3-channel isolator, a CAN transceiver, and an Analog DevicesisoPower®dc-to-dc converter into a single, surface-mount, small outline integrated circuit (SOIC) package. The devices are powered by a single 5 V supply, realizing a fully isolated solution for CAN and CAN FD. Radiated emissions from the high frequency switching of the dc-to-dc convertors are kept below EN 55022 Class B limits by continuous adjustments to the switching frequency.The ADM3055E/ADM3057E provide complete isolation between the CAN controller and physical layer bus. Safety and regulatory approvals (pending) for 5 kV rms isolation voltage, 10 kV surge test, and 8.3 mm creepage and clearance ensure the ADM3055E meets application reinforced isolation requirements. The ADM3057E has an isolation voltage of 3 kV rms and 7.8 mm creepage in a 20-lead, wide body SOIC.Low propagation delays through the isolation support longer bus cables. Slope control mode is available for standard CAN at low data rates. Standby mode minimizes power consumption when the bus is idle or if the node goes offline. Silent mode allows the TXD input to be ignored for listen only mode.Dominant timeout functionality protects against bus lock up in a fault condition. The current limiting and thermal shutdown features protect against output short circuits. The devices are fully specified over an industrial temperature range of −40°C to +105°C.ApplicationsCANOpen, DeviceNet, and other CAN bus implementationsIndustrial automationProcess control and building controlTransport and infrastructure
