Product Details
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.
