MAX22520

One-Time Programmable (OTP)

Industrial Sensor Output Driver

General Description

Beneﬁts and Features

● High Configurability Supports a Wide Range of

The MAX22520 24V line driver for industrial sensors incor-

porates 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.

Sensor Designs

• Programmable Driver Conﬁguration: High-Side

(PNP), Low-Side (NPN), or Push-Pull

• Programmable Driver Current Limit: 100mA (min),

200mA (min)

• Programmable Linear Regulator Voltage: 3.3V

(typ), 5V (typ)

• Input Comparator with Programmable Thresholds

• Digital Potentiometer with Programmable 6-bit Tap

• PWM Oscillator with Programmable Duty Cycles

• 4.75V/8V (min) to +36V Supply Voltage

• Integrated LED Driver for Visual Feedback

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).

● Robust Design for Harsh Industrial Environments

Configuration and OTP programming are done using

• Reverse Polarity Protection on DO, V , and GND

• Short Circuit Protection on DO

• Thermal Shutdown Protection

• ±6kV IEC 61000-4-2 Air-Gap ESD Protection

• ±6kV IEC 61000-4-2 Contact Discharge ESD

Protection

• ±1kV/500Ω IEC 61000-4-5 Surge Protection

• -40°C to +105°C Operating Temperature Range

• 1µF Capacitive Load Drive Capability

• Fast Demagnetization of Inductive Loads

, 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 com-

parator, 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

● Small Form Factor for Compact Designs

harsh industrial environments. DO, V , and GND are

• Ultra-Small (2mm x 2.5mm) 20-bump WLP

all protected against hot-plug events, ±1kV/500Ω surge

events, reverse-polarity, short circuits, and ESD strikes.

Ordering Information appears at end of data sheet.

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.

Applications

● Industrial Binary Sensors

● Proximity Switches

● Inductive and Magnetic Sensors
