MAX14838/MAX14839  
24V Pin-Configurable Industrial Sensor  
Output Drivers  
General Description  
The MAX14838/MAX14839 24V/100mA drivers are  
optimized for use in industrial sensors. These devices  
integrate all of the high-voltage (24V) circuitry commonly  
found in industrial sensors, including a configurable PNP/  
NPN/push-pull driver and an integrated linear regulator  
that meets common sensor power requirements.  
Benefits and Features  
● High Configurability Simplifies Design  
• Pin-Selectable High-Side (PNP), Low-Side (NPN),  
or Push-Pull Driver  
• Pin-Configurable NO/NC Logic  
● Integrated Protection Provides Robust Sensor  
Solutions  
The MAX14838/MAX14839 are pin-configurable. Logic  
inputs allow the driver to be configured for high-side  
(PNP), low-side (NPN), or push-pull operation. An  
additional input allows the user to select between normal-  
ly-open and normally-closed logic.  
• Reverse-Polarity Protection on DO, V , and GND  
• 4.75V to 34V Supply Range (MAX14839)  
• Driver is Short-Circuit Protected  
CC  
• FAULT Output for Fault Indication  
• V  
Hot Plug Protection  
The MAX14838 features an onboard 5V linear regulator,  
while the MAX14839 features a 3.3V linear regulator.  
CC  
• Thermal Shutdown Protection  
• ±1kV/500Ω Surge Protection  
Each device includes two LED drivers for visual feedback.  
One LED driver reflects the output logic status and the  
other is a general-purpose driver that can be used to  
signal a fault condition.  
• ±8kV IEC 61000-4-2 Air Gap ESD Protection  
• ±6kV IEC 61000-4-2 Contact ESD Protection  
• -40°C to +105°C Temperature Range  
● Fast Turn-Off of Inductive Loads Up to 1.5H  
The DO output, supply (V ), and ground (GND) pins are  
CC  
reverse polarity-protected and are protected against IEC  
● Saves Space on Board  
• Available in 12-Pin TDFN-EP (3mm x 3mm) or  
12-Bump WLP (2.1mm x 1.6mm)  
• Dual Integrated 2mA LED Drivers  
ESD and surge events.  
The MAX14838 and MAX14839 operate from a wide sup-  
ply range 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°C  
temperature range.  
Applications  
● Industry Binary Sensors  
● Proximity Switches  
● Capacitive and Inductive Sensors
