Product details

It delivers a 4A peak output current, which is enough to drive medium-power MOSFETs and IGBTs in half-bridge or full-bridge configurations. The 35kV/µs minimum common-mode transient immunity (CMTI) means it will hold the gate drive clean even when the switching node is slamming through several hundred volts in tens of nanoseconds — a spec that matters directly for motor-drive and inverter designs where noise-induced false triggering is a risk.

Timing margins and switching performance

Propagation delay is 160ns max from input to output, matched within 14ns pulse-width distortion. Rise and fall times are 14ns typical. These numbers are tight enough for switching frequencies up to a few hundred kilohertz without eating into the dead-time budget. The 12V to 18V output supply range matches the typical gate drive voltage for standard MOSFETs and IGBTs.

Package and temperature grade for industrial environments

UR approval is listed, which helps for UL-recognized end-equipment compliance.

Frequently asked questions

Can ADUM7234BRZ-RL7 drive IGBTs?

Yes, with its 4A peak output current and 12V to 18V output supply range, it can drive medium-power IGBTs in half-bridge or full-bridge topologies, provided the gate charge and switching frequency stay within the thermal budget.

What is the closest pin-compatible equivalent to ADUM7234BRZ-RL7?

Within the iCoupler family, the ADUM7234BRZ (non-tape-and-reel variant) is the same die and package, differing only in the shipping medium. For a second source, parts like the Si8261BCC-IS from Silicon Labs offer similar isolation and drive strength but are not pin-compatible — verify the footprint before substituting.
