ADUM7223

Isolated Precision Half-Bridge Driver, 4 A Output
Manufactured by:

Product Details

The ADuM7223 is a 4A isolated, half-bridge gate driver that employ Analog Devices, Inc.’s iCoupler® technology to provide independent and isolated high-side and low-side outputs. Combining high speed CMOS and monolithic transformer technology, these isolation components provide outstanding performance characteristics superior to alternatives such as the combination of pulse transformers and non-isolated gate drivers. By integrating the isolator and driver in a single package, propagation delay is a maximum of only 60 ns and the propagation skew from channel to channel is a maximum of only 7ns.The ADuM7223 provides two independent isolation channels. 

The ADuM7223 operates with an input supply ranging from 3.0 V to 5.5 V, providing compatibility with lower voltage systems. The outputs operate in a wide range from 4.5V to 18V with three output voltage versions available. The 5 x 5 mm, LGA package provides 2500 VDC PEAK operating voltage from input to output and from output to output.

In comparison to gate drivers employing high voltage level translation methodologies, these gate drivers offer the benefit of true, galvanic isolation between the input and each output. As a result, these gate drivers provide reliable control over the switching characteristics of IGBT/MOSFET configurations over a wide range of positive or negative switching voltages.

Applications

  • Switching power supplies
  • Isolated IGBT/MOSFET gate drives
  • Industrial inverters

EVAL-ADUM7223 Circuit Diagram

Product Details

The EVAL-ADUM7223EBZ supports the ADuM7223 isolated precision half-bridge driver. Because the evaluation boards have footprints for IGBTs and MOSFETs in TO-252 packages, the ADuM7223 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.
