Introduction

AI Translation

The MAX22195 translates eight 24V industrial digital inputs to eight CMOS-compatible, parallel outputs. Propagation delay from input-to-output is less than 300ns for all channels. Current-limiters on each digital input greatly reduce power dissipation compared to traditional resistive inputs. The accuracy of these current-limiters minimizes power dissipation while ensuring compliance with the IEC 61131-2 standard. A current-setting resistor allows the MAX22195 to be configured for Type 1, Type 2, or Type 3 inputs. Additionally, the MAX22195 has energyless fieldside LED drivers to meet the indicator light requirement of IEC 61131-2 with no additional power dissipation. The MAX22195 provides a 3.3V integrated voltage regulator. The internal LDO accepts the field supply VDD24 from 7V to 65V. The internal LDO output can supply up to 25mA of current in addition to powering the basic MAX22195 requirements. This MAX22195 LDO current can be used to power digital isolators and other field-side circuits. Alternatively, the MAX22195 can be powered from a 3.0V to 5.5V supply connected to VDD3 pin. The MAX22195 includes an open-drain READY output that asserts high to indicate the MAX22195 is functional. If the VDD24 field-side supply voltage is too low, or a fault in the current-setting resistor is detected, or the device reaches an over-temperature condition, the READY signal is set to high-impedance.
