Product details

Single-channel low-side driver for IGBT and N-channel MOSFET gates

It accepts both inverting and non-inverting input signals, giving flexibility in control logic interfacing.

Switching speed and drive strength for power-stage design

The 8 A sink capability handles the gate charge of medium-power IGBTs and MOSFETs without an external booster stage. The 8 ns rise and 7 ns fall times (typical) mean the driver can switch at frequencies where propagation delay and dead-time margins are tight — useful in synchronous rectification and motor-drive half-bridges.

Frequently asked questions

What is the typical rise and fall time of UCC27511ADBVR?

Typical rise time is 8 ns and fall time is 7 ns, measured under standard test conditions. These fast edges minimise switching losses in the driven power device.

Can UCC27511ADBVR drive IGBTs?

Yes, the gate type is specified for IGBT and N-Channel MOSFET. The 8 A peak sink current provides sufficient gate charge for small to medium IGBTs in low-side switching applications.

How does UCC27511ADBVR compare to UCC27511DBVR?

Both share the same base product number UCC27511 and identical pinout and package. The 'A' suffix in UCC27511ADBVR typically indicates a tighter specification or enhanced performance variant — the exact parametric differences should be verified against the datasheet for your specific application.
