MAX14483AAP+ IC Pinout (20-pin SSOP)

Notes

• MAX14483EVKIT is a fully assembled evaluation kit containing the MAX14483AAP+ IC in a 20-pin SSOP package with 5.5mm creepage and clearance.
• The IC provides 6 unidirectional isolation channels (SDO, FAULT, AUX, SDI, SCLK, CS) with galvanic isolation up to 3.75kV RMS for 60 seconds.
• OFAULT is an open-drain output with a 10kΩ pull-up resistor on the evaluation board.
• OSDO output can be disabled via the SDOEN pin; when both SDOEN and ICS are high, OSDO is high-impedance.
• SAA and SBA are status outputs indicating Side A and Side B are ready for communication (active high).
• The evaluation kit includes SMA connectors and test points for all six channels, plus jumpers (J1, J2, IRDYB, SDOENB) for configuration and current measurement.
• Power supply range: 1.71V to 5.5V on both VDDA and VDDB (can be independent or from a single supply).
