Features and Benefits

  • 4 A peak output current
  • High frequency operation: 1 MHz maximum
  • CMOS input logic levels
  • 4.5 V to 18 V output drive
  • Supports TO-263 or TO-252 IGBT/MOSFETs
  • Bootstrap option

Product Details

The EVAL-ADuM3223AEBZ and EVAL-ADuM4223AEBZ support the ADuM3223 and ADuM4223 isolated precision half-bridge drivers, respectively. Because the evaluation boards have footprints for IGBTs and MOSFETs in TO-263 or TO-252 packages, the ADuM3223 and ADuM4223 can be evaluated with many different power devices. The evaluation boards also allow the high-side supply to be bootstrapped to the low-side supply.


The ADuM3223A model represents a superset of the ADuM3223 models because it has the lowest minimum output voltage (4.5 V). The ADuM3223B and ADuM3223C models have minimum out-put voltages of 7.5 V and 11.5 V, respectively. In the same way, the ADuM4223A model represents a superset of the ADuM4223 models.


Complete information about the ADuM3223 and ADuM4223 is available in the ADuM3223/ADuM4223 data sheet, which should be consulted in conjunction with UG-368 when using the evaluation board.

Isolated DC-DC converter design?

RE: Adum3223 why is the output VOA VOB high when vdd1 = 5V and via VIB = 3.3V? In the specification, when vdd1 = 5V, via VIB needs to be greater than 0.7 * vdd1 = 0.7 * 5V = 3.5V, and the output above 3.5V is high level?
