MAX22199

Octal Industrial Digital Input

General Description

Beneﬁts and Features

The MAX22199 is an IEC 61131-2 compliant industrial

digital input device. The MAX22199 translates eight 24V

current-sinking industrial inputs to a serialized SPI-

compatible output that interfaces with 3V to 5.5V logic.

It can operate as eight Type 1/Type 3 digital inputs or

four Type 2 digital inputs. The device provides diagnostic

functions, including thermal shutdown, 24V under volt-

age alarm, 24V missing voltage alarm, and SPI and CRC

communication error detection. All of the faults can be

configured to generate an interrupt using the FAULT pin.

● High Integration Reduces BOM Count and Board Space

• Eight Input Channels with Serializer

• Operates Directly from Field Supply (7V to 65V)

• Compatible with 3.3V or 5V Logic

• 5mm x 5mm TQFN Package

● Reduced Power and Heat Dissipation

• 0.6mA (typ) Supply Current

• ±11% Accurate Input-Current Limiters

• Energyless Field-Side LED Drivers

• Low Power Dissipation with Negative Input Voltage

● Fault Tolerant

For robust operation in industrial environments, each

input includes a programmable glitch filter. Noise filters on

each channel can be independently programmed to one

of eight values between 50µs and 20ms or filter bypass.

• Input Protection to ±40V

• Integrated Field-Supply Voltage Monitors

• 5-Bit CRC SPI Error Detection

● Configurability Enables Wide Range of Applications

• Conﬁgurable Input Current from 0.5mA to 3.4mA

• Selectable Input Debounce Filtering

• Current Sources Can Be Disabled

• Supports Daisy-Chain SPI and Direct SPI

● Robust Design

• ±8kV Contact ESD and ±15kV Air-Gap ESD Using

Minimum 1kΩ Resistor

• ±2kV Surge Tolerant Using Minimum 1kΩ Resistor

• -40°C to +125°C Ambient Operating Temperature

● Advanced Diagnostics Can Be Provided by MAX22190

• Pin-to-Pin Compatible

The MAX22199 has a 4-pin SPI interface and, in addition,

uses the LATCH input for synchronizing input data sam-

pling across multiple devices.

The MAX22199 field-side accepts a single 7V to 65V

supply to the V

pin. When powered by the field

DD24

supply, the MAX22199 generates a 3.3V output from an

integrated LDO regulator, which can provide up to 25mA

of current for external loads in addition to powering the

MAX22199. Alternatively, the MAX22199 can be powered

from a 3.0V to 5.5V logic side supply connected to the

pin. For flexibility, the SPI interface operates at 3.3V

or 5V logic levels as controlled by the V pin.

• Register Compatible

Applications

● Programmable Logic Controllers

● Distributed Control System

● Motor Control
