Key Features
- 3 kVRMS isolation barrier provides galvanic separation between control and power stages for safety and noise immunity
- Symmetric 5 A source / 5 A sink output current drives IGBTs and MOSFETs with fast switching transitions
- Built-in Miller clamp prevents parasitic turn-on during fast dV/dt switching events in hard-switching topologies
Applications
The UCC5350MCD is designed for driving IGBTs and MOSFETs in isolated power converter applications such as solar inverters, motor drives, and uninterruptible power supplies. Its 3 kVRMS isolation rating ensures safe separation between the controller and high-voltage power stage in grid-connected and industrial systems. The differential input interface and Miller clamp feature make it well suited for high-frequency hard-switching converters where spurious turn-on must be suppressed.

Frequently Asked Questions
What is the isolation voltage rating of the UCC5350MCD?
The UCC5350MCD provides 3 kVRMS reinforced isolation between the input (logic) side and the output (gate driver) side. This rating ensures safe galvanic separation in applications where the power stage operates at high voltages, such as motor drives, solar inverters, and industrial power converters connected to AC mains.
What is the Miller clamp feature in the UCC5350MCD and why is it important?
The Miller clamp is an active circuit that holds the gate of the power device LOW during turn-off transitions when the drain or collector voltage rises rapidly (high dV/dt). Without a clamp, the Miller capacitance can couple enough charge into the gate to cause spurious turn-on, leading to shoot-through and potential device damage. The built-in Miller clamp (M variant) suppresses this effect without requiring an external clamp circuit.
What output drive current does the UCC5350MCD provide?
The UCC5350MCD provides 5 A peak source current and 5 A peak sink current symmetrically. This allows fast charging and discharging of the gate capacitance of large IGBTs and MOSFETs, enabling high switching frequencies with controlled rise and fall times to minimize switching losses.
What protection features are built into the UCC5350MCD?
The UCC5350MCD includes under-voltage lockout (UVLO) protection, which disables the gate driver output when the supply voltage falls below the minimum operating threshold to prevent incomplete gate switching. It also includes transient protection to withstand high common-mode voltage transients across the isolation barrier, which are common in fast-switching power converter environments.
