EVALUATION KIT AVAILABLE

MAX14001/MAX14002

Conﬁgurable, Isolated 10-bit ADCs for

Multi-Range Binary Inputs

General Description

The MAX14001/MAX14002 are isolated, single-channel

analog-to-digital converters (ADCs) with programmable

voltage comparators and inrush current control optimized

Beneﬁts and Features

● Enables Robust Detection of Binary Inputs

• Programmable Input Bias Current Rejects Line Noise

• 3.75kV

of Isolation for 60 Seconds

RMS

for configurable binary input applications. 3.75kV

• 5.5mm of Creepage and Clearance

• Group II CTI Package Material

RMS

of integrated isolation is provided between the binary

input side (field-side) and the comparator output/SPI-side

(logic-side) of the MAX14001/MAX14002. An integrated,

isolated, DC-DC converter powers all field-side circuitry,

and this allows running field-side diagnostics even when

no input signal is present. The 20-pin SSOP package

provides 5.5mm of creepage and clearance with group II

CTI rating.

● Reduces BOM and Board Space Through High

Integration

• 10-bit, 10ksps ADC

• Binary Threshold Comparators

• Control Circuit for Driving a Depletion Mode FET

• Isolation for Both Data and DC-DC Supply

• 20-SSOP Package

These devices continually digitize the input voltage on

the field-side of an isolation barrier and transmit the data

across the isolation barrier to the logic-side of the device

where the magnitude of the input voltage is compared to

programmable thresholds. The binary comparator output

pin is high when the input voltage is above the upper

threshold and low when it is below the lower threshold.

Response time of the comparator to an input change

is less than 150µs with filtering disabled. With filtering

enabled, the comparator uses the moving average of the

last 2, 4, or 8 ADC readings. Both filtered and unfiltered

ADC readings are available through the 5MHz SPI port,

which is also used to set comparator thresholds and other

device configuration.

● Increases Equipment “Up Time” and Simplifies

System Maintenance

• Enables Field-Side Diagnostics

• Automatic Self-Diagnostics

● Provides Unparalleled Flexibility

• Programmable Upper and Lower Input Thresholds

• Programmable Inrush Current Activation Threshold,

Magnitude, and Duration

• Daisy-Chainable SPI Interface

Applications

● High-Voltage Binary Input (12V–300V)

● Distribution Automation

● Substation Automation

The MAX14001/MAX14002 control the current of a binary

input through an external, high-voltage FET. This current

cleans relay contacts and attenuates input noise. An inrush

comparator monitoring theADC readings triggers the inrush

current, or wetting pulse. The inrush trigger threshold, current

magnitude, and current duration are all programmable

in the MAX14001 but are fixed in the MAX14002. When the

high-voltage FET is not providing inrush current, it switches

to bias mode. Bias mode places a small current load on the

binary input to attenuate capacitively coupled noise. The

level of bias current is programmable between 50µA and

3.75mA in both the MAX14001 and MAX14002. This allows

optimization of the tradeoff between noise attenuation and

power dissipation.

● Industrial Control, Multi-Range, Digital Input Modules

with Individually Isolated Inputs

Safety Regulatory Approvals (Pending)

● UL According to UL1577
