The MAX22192 is an IEC 61131-2 compliant industrialdigital input device with integrated digital isolation. TheMAX22192 translates eight, 24V current-sinking, industrialinputs to an isolated serialized SPI-compatible outputthat interfaces with 1.71V to 5.5V logic voltage. A current-settingresistor allows the MAX22192 to be configured forType 1, Type 2, or Type 3 inputs. For proximity switches,the field-wiring is verified using the wire break feature.When wire break is enabled, the active-low LFAULT output is assertedand a register flag set if the input current drops belowthe wire break threshold for more than 20ms. Additionaldiagnostics that assert active-low LFAULT include: overtemperatureprotection, low 24V field supply, 24V field supply missing,and CRC communication error.For robust operation in industrial environments, each inputincludes a programmable glitch filter. The filter delay oneach channel can be independently programmed to oneof eight values between 50µs and 20ms, or filter bypass.The MAX22192 has an isolated 4-pin SPI interface, andin addition uses isolated active-low LLATCH input for synchronizinginput data across multiple devices in parallel, and isolatedactive-low LFAULT output for instantly alerting the host of anydiagnostic issues. The digital signals with a name startingwith L are logic-side signals, and the digital signals with aname starting with F are field-side signals.The MAX22192 field-side accepts a single 7V to 65V supplyto the VDD24F pin. When powered by the field supply,the MAX22192 generates a 3.3V output on the VDD3F pinfrom an integrated LDO regulator, which can provide up to25mA of current for external loads in addition to poweringthe MAX22192. Alternatively, the MAX22192 can be poweredfrom a 3.0V to 5.5V supply connected to the VDD3Fpin.

The MAX22201/MAX22202/MAX22207 integrate one36V, 3.5A peak full bridge capable of driving one brushedDC motor. The full bridge features very low impedanceFETs with a typical RON (high side + low side) of 0.3Ω resultingin high driving efficiency. The peak current ratingof 3.5A is limited by the overcurrent protection threshold(OCP). The peak current is defined as the maximum currentthe driver can provide for short transients. The maximumRMS current is 2A and is typically limited by thermalconsiderations. The 2ARMS capability refers to a standardJEDEC 4-layer board at 25°C ambient temperature. Thereal operating maximum current depends on the applicationthermal characteristic (PCB ground planes, heatsinks, ventilation, etc.).The MAX22201/MAX22202/MAX22207 feature a non-dissipativeand accurate integrated current sensing (ICS) andan embedded internal current drive regulation (CDR) circuitto monitor the current through a motor coil and limitthe peak output current. When the motor current exceedsthe current limit threshold, the full bridge enters a decaymode for a fixed off time (tOFF). For brushed motor driveapplications, the current drive regulation guarantees safeand reliable operation of the driver under normal conditionsor during motor startup and stall conditions, and alsoreduces system power and supply bypassing requirements.A scaled copy of the internally sensed current isoutput to an external pin (ISEN). For more information onthese features, refer to the Detailed Description.All versions feature overcurrent protection (OCP), thermalshutdown (TSD), and undervoltage lockout (UVLO).

The USB port is protected against connection to typical 24VDC or 24VAC systems with a max data line protection of ±40.7V and power/ground line protection up to ±50V.VBUS, ground and connector shield connections can be configured for any level of ESD, burst, and surge protection by choosing external components. USB data D+ and D- are protected by external diode clamps to VBUS and GND, allowing for the lowest possible insertion loss while providing high ESD and Burst protection. The MAX22505 is housed in a 24-pin, 4mm x 4mm TQFN package with exposed pad and is specified for operation over the -40°C to +105°C temperature range.Design Solution: Protecting Your USB Port Doesn’t Have to Slow It Down ›ApplicationsDiagnostic USB portIndustrial PCProgrammable Logic Controller (PLC)

The MAX22513 dual-channel low power IO-Link device transceiver features a selectable control interface, internal high-efficiency DC-DC buck regulator, two internal linear regulators, and integrated surge protection for robust communication. The device features low-on resistance drivers (C/Q and DO/DI), selectable driver current limits, and overcurrent protection to reduce power dissipation in small sensor applications.The DC-DC buck regulator supplies up to 300mA load current and has an adjustable output voltage (from 2.5V to 12V). Internal linear regulators generate 5V and 3.3V, supplying up to 50mA of current. The MAX22513 can be controlled using SPI or I2C interfaces, providing flexibility for microcontrollers, and extensive control and diagnostic features. Both full- and half-duplex SPI are supported. The internal MCLK oscillator provides a clock source to a microcontroller for IO-Link communication.The MAX22513 features extensive integrated protection to ensure robust communication in harsh industrial environments. All four IO pins (V24, C/Q, DO/DI, and GND), are reverse voltage protected, short circuit protected, and feature integrated ±1kV/500Ω surge protection.The MAX22513 is available in a tiny WLP package (4.1mm x 2.1mm) or 28-pin TQFN-EP package (3.5mm x 5.5mm) and operates over the -40°C to +125°C temperature range.ApplicationsIndustrial SensorsIO-Link Sensor and Actuator Devices
