MAX14933Two-Channel, 2.75kVRMSI2C Isolator | Evaluation Boards | 6 | Active | The MAX14933 is a two-channel, 2.75kVRMSI2C digital isolator utilizing Maxim’s proprietary process technology. For applications requiring 5kVRMSof isolation, refer to the MAX14937 data sheet. The MAX14933 transfers digital signals between circuits with different power domains at ambient temperatures up to +125°C.The device offers two bidirectional, open-drain channels for applications, such as I2C, that require data to be transmitted in both directions on the same line. To prevent latch-up action, the A-side outputs comprise special buffers that regulate the logic-low voltage at 0.9V (max), and the input logic-low threshold is at least 50mV lower than the output logic-low voltage. The B side features conventional buffers that do not regulate logic-low output voltage.The device features independent 2.25V to 5.5V supplies on each side of the isolator. The device operates from DC to 1.7MHz and can be used in isolated I2C busses with clock stretching.The MAX14933 is available in both a 16-pin wide-body (10.3mm x 7.5mm) and narrow-body (9.9mm x 3.9mm) SOIC package. All devices are rated for operation at ambient temperatures of -40°C to +125°C.ApplicationsBattery ManagementI²C, SMBus, PMBus™ InterfacesInstrumentationPower Supplies |

MAX14936Four-Channel, 5kVRMSDigital Isolators | Isolators | 12 | Active | The MAX14934–MAX14936 are a family of four-channel, 5kVRMSdigital isolators utilizing Maxim’s proprietary process technology. For applications requiring 2.75kVRMSof isolation, see the MAX14930–MAX14932. The MAX14934–MAX14936 family transfers digital signals between circuits with different power domains at ambient temperatures up to +125°C.The MAX14934–MAX14936 family offers all three possible unidirectional channel configurations to accommodate any four-channel design, including SPI, RS-232, RS-485, and large digital IO modules. For applications requiring bidirectional channels, such as I²C, refer to the MAX14937.Devices are available with data rates from DC up to 1Mbps, 25Mbps, or 150Mbps. Each device is also available in either a default high or default low configuration. The default is the state an output goes to when its input is unpowered. See the Product Selector Guide and Ordering Information for the suffixes associated with each option. Independent 1.71V to 5.5V supplies on each side of the isolator also make the devices suitable for use as level translators.The MAX14934–MAX14936 are available in a 16-pin wide body (10.3mm x 7.5mm) SOIC package. All devices are rated for operation at ambient temperatures of -40°C to +125°C.ApplicationsBattery ManagementFieldbus Communications for Industrial AutomationGeneral Multichannel Isolation ApplicationsIsolated SPI, RS-232, RS-485/RS-422Medical Systems |

MAX149392.75kVRMSIsolated 20Mbps Half-Duplex PROFIBUS/RS-485 Transceivers with ±35kV ESD Protection | Digital Isolators | 2 | Active | The MAX14938/MAX14939 isolated RS-485/PROFIBUS-DP transceivers provide 2750VRMS(60s) of galvanic isolation between the cable side (RS-485 driver/receiver side) and the UART side of the device. Isolation improves communication by breaking ground loops and reduces noise when there are large differences in ground potential between ports. These devices allow for robust communication up to 20Mbps.An integrated LDO provides a simple and space-efficient architecture for providing power to the cable side of the IC.Each device includes one half-duplex driver/receiver channel. The receiver is 1/4-unit load, allowing up to 128 transceivers on a common bus.Integrated true fail-safe circuitry ensures a logic-high on the receiver output when inputs are shorted or open. Undervoltage lockout disables the driver when cable-side or UART-side power supplies are below functional levels.The driver outputs/receiver inputs are protected from ±35kV electrostatic discharge (ESD) to GNDB on the cable side, as specified by the Human Body Model (HBM).The MAX14938/MAX14939 are available in a wide-body 16-pin SOIC package and operate over the -40°C to +105°C temperature range.ApplicationsHVACIndustrial Automation EquipmentPower MetersProgrammable Logic Controllers |
