MAX22520One-Time Programmable (OTP) Industrial Sensor Output Driver | Interface | 2 | Active | The MAX22520 24V line driver for industrial sensors incorporates a one-time programmable (OTP) analog interface for signal conditioning of binary switching sensors. Sensor calibration and configuration settings can be permanently programmed with the inline data interface using one-time programming (OTP). Additionally, an accurate integrated linear regulator provides a programmable (3.3V or 5V) low-noise supply for analog signal sensing circuitry.The driver output (DO) is configurable using the Maxim®1-Wire®protocol and an OTP interface to permanently operate in a normally-open or normally-closed state and in a high-side (PNP), low-side (NPN), or push-pull configuration. The maximum driver load current can be programmed to 100mA (min) or 200mA (min).Configuration and OTP programming are done using VCC, DO, and GND. This use of the standard three-wire interface pins simplifies programming at the end-of-line, when the sensor is already in its final housing.The MAX22520 also features a programmable comparator, PWM oscillator, and digital potentiometer. These integrated functions further support sensor calibration for analog sensing circuitry. Additionally, an on-board LED driver provides visual feedback of the logic state of the sensor DO output.Robust protection enables the MAX22520 to function in harsh industrial environments. DO, VCC, and GND are all protected against hot-plug events, ±1kV/500Ω surge events, reverse-polarity, short circuits, and ESD strikes.The MAX22520 operates from a wide 4.75V/8V to 36V supply and is available in a 20-bump wafer-level package (WLP) (2mm x 2.5mm, 0.5mm pitch). The device operates over the -40°C to +105°C temperature range.ApplicationsIndustrial Binary SensorsProximity SwitchesInductive and Magnetic Sensors |
MAX22530Field-Side Self-Powered, 4-Channel, 12-bit, Isolated ADC | Data Acquisition | 2 | Active | The MAX22530–MAX22532 are galvanically isolated, 4-channel, multiplexed, 12-bit, analog-to-digital converters (ADC) in the MAXSafe™family product line. An integrated, isolated, DC-DC converter powers all field-side circuitry, and this allows field-side diagnostics even when no input signal is present.The MAX22530–MAX22532 family continually digitizes the input voltage on the field-side of an isolation barrier and transmits the data across the isolation barrier to the logic-side of the devices where the magnitude of the input voltage is compared to programmable thresholds. The 12-bit ADC core has a sample rate of 20ksps (typ) per-channel. ADC data is available through the SPI interface either directly or filtered. Filtering averages the most recent 4 readings depending on the setting.Each input has a comparator with programmable high and low thresholds, and an interrupt is asserted when any input crosses its programmed level based on the mode setting. The comparator output pin (COUT_) is high when the input voltage is above the upper threshold and low when it is below the lower threshold in digital input mode. Typical response time of the comparator to an input change is less than 75µs with filtering disabled. With filtering enabled, the comparator uses the moving average of the last 4 ADC readings.The MAX22530 in a 16-pin wide SOIC package provides 8mm of creepage and clearance, and 5kVRMS isolation. The MAX22531 in a 20-pin SSOP package and the MAX22532 in a 28-pin SSOP package, both provide 5.5mm of creepage and clearance, and 3.5kVRMS isolation. All package material has a minimum comparative tracking index (CTI) of 400, which gives it a group II rating in creepage tables.All devices are rated for operation at ambient temperatures between -40°C to +125°C.ApplicationsHigh-Voltage Binary InputSubstation AutomationDistribution AutomationProcess AutomationMotion Control |
