Description

The MAX14838/MAX14839 24V/100mA drivers areoptimized for use in industrial sensors. These devicesintegrate all of the high-voltage (24V) circuitry commonlyfound in industrial sensors, including a configurable PNP/NPN/push-pull driver and an integrated linear regulatorthat meets common sensor power requirements.The MAX14838/MAX14839 are pin-configurable. Logicinputs allow the driver to be configured for high-side(PNP), low-side (NPN), or push-pull operation. Anadditional input allows the user to select between normally-open and normally-closed logic.The MAX14838 features an onboard 5V linear regulator,while the MAX14839 features a 3.3V linear regulator.Each device includes two LED drivers for visual feedback.One LED driver reflects the output logic status and theother is a general-purpose driver that can be used tosignal a fault condition.The DO output, supply (VCC), and ground (GND) pins arereverse polarity-protected and are protected against IECESD and surge events.The MAX14838 and MAX14839 operate from a wide supplyrange and are available in a 12-pin TDFN-EP package(3mm x 3mm) or a 12-bump wafer-level package (WLP)(2.1mm x 1.6mm) and operate over the -40°C to +105°Ctemperature range.ApplicationsCapacitive and Inductive SensorsIndustry Binary SensorsProximity Switches
