MAX22191
EVALUATION KIT AVAILABLE
Parasitically Powered Digital Input
General Description
The MAX22191 is an IEC 61131-2 compliant, industrial
digital input (DI) device that translates a 24V digital industrial
input to a 2.4mA (typ) current for driving optical isolators.
Voltage thresholds and current levels in the MAX22191
are compliant with Type 1 and Type 3 inputs, while minimizing
power dissipation. The MAX22191 is also compliant with
48V inputs, with the addition of external resistors.
Operating power is derived from the input signal, eliminating
the need for an external field-side power supply. A 250ns
(max) fast response time is ideal for high-speed inputs.
Additionally, a CMOS-compatible test input is available for
safety diagnostics.
The MAX22191 features robust functionality for harsh
industrial systems and is capable of normal operation with
input signals ranging from -60V to +60V. Integrated thermal
shutdown further protects the device when VCC is present.
The MAX22191 is available in a small, 6-lead SOT23
package and operates over the -40°C to +125°C ambient
temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
