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

• 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.

• 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

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
