The MAX22163−MAX22166 are a family of six-channel, reinforced, fast, low-power digital galvanic isolators using Analog Devices’ proprietary process technology. All devices feature reinforced isolation with a withstand voltage rating of 3kVRMSfor 60 seconds. Both automotive and general-purpose devices are rated for operation at ambient temperature from -40°C to +125°C. Devices with /V suffix are AEC-Q100 qualified. See the Ordering Information for all automotive grade part numbers.IndustrialIsolated SPI, RS-232/422/485, CAN, Digital I/OFieldbus CommunicationsMotor ControlMedical SystemsThese devices transfer digital signals between circuits with different power domains, using as little as 0.71mW per channel at 1Mbps (1.8V supply). The low-power feature reduces system dissipation, increases reliability, and enables compact designs. Devices are available with a maximum data rate of either 25Mbps or 200Mbps and with default-high or default-low outputs. The devices feature low propagation delay and low clock jitter, which reduces system latency.Independent 1.71V to 5.5V supplies on each side also make the devices suitable for use as level translators.The MAX22163 features three channels transmitting digital signals in one direction and three in opposite; the MAX22164 offers four channels transmitting digital signals in one direction and two in opposite; the MAX22165 provides five channels transmitting digital signals in one direction and one in opposite; the MAX22166 features all six channels transmitting digital signals in one direction.ApplicationsAutomotiveBattery Management System (BMS)ChargersHybrid Electric VehicleInverters

The MAX22193 translates four 24V industrial digital inputs to four CMOS-logic-compatible, parallel outputs. Propagation delay from input-to-output is less than 300ns for all four channels. Current-limiter on each digital input greatly reduces power dissipation compared to traditional resistive input. The accuracy of these current-limiters minimizes power dissipation while ensures compliance with the IEC 61131-2 standard. A current-setting resistor allows the MAX22193 to be configured for Type 1, Type 2 or Type 3 digital inputs. Additionally, the MAX22193 has energyless field-side LED drivers to meet the indicator light requirement of IEC 61131-2 with no additional power dissipation.The MAX22193 provides a 3.3V integrated voltage regulator. The internal LDO accepts the field supply VDD24from 7V to 65V. The internal LDO output can supply up to 25mA of current in addition to powering the basic MAX22193 requirements. This LDO can be used to power digital isolators and other field-side circuits. Alternatively, the MAX22193 can be powered from an external 3.0V to 5.5V supply at VDD3.The MAX22193 includes an open-drain READY output that asserts high to indicate the MAX22193 is functional. If the VDD24field-side supply voltage is too low, or a fault in the current-setting resistor is detected, or the device reaches an over-temperature condition, the READY signal is set to high-impedance.ApplicationsProgrammable Logic Controllers (PLC)Distributed Control System (DCS)Motor ControlIndustrial AutomationProcess Automation
