Key Features
- 5.7 kVrms reinforced isolation between input and output channels for high-voltage power conversion safety
- Asymmetric 4A source / 6A sink peak gate drive current for fast IGBT and MOSFET switching
- Built-in under-voltage lockout (UVLO) protection preventing erratic switching during supply ramp-up
- Dual-channel half-bridge configuration in a compact 16-SOIC package for high-density power stage designs
Applications
The UCC21520DW isolated gate driver is ideal for half-bridge and full-bridge power converter designs in solar inverters, motor drives, and industrial power supplies where high-voltage isolation between the controller and power stage is required. Its 5.7 kVrms isolation rating makes it suitable for high-voltage DC bus applications such as three-phase inverters operating from 600V to 1200V bus rails. The device also fits EV on-board chargers and server power supply units needing reliable, fast gate drive with integrated protection.

Frequently Asked Questions
What is the isolation voltage rating of the UCC21520DW?
The UCC21520DW provides 5.7 kVrms reinforced galvanic isolation between the input logic side and the high-voltage output side. This isolation rating meets safety standards for industrial and EV power conversion systems operating at high DC bus voltages up to 1200V.
What are the peak output current capabilities of the UCC21520DW?
The UCC21520DW delivers a peak source current of 4A and a peak sink current of 6A per channel. The asymmetric drive capability allows faster turn-off than turn-on, which reduces switching losses and shoot-through risk in half-bridge power stages.
What protection features does the UCC21520DW include?
The UCC21520DW incorporates built-in under-voltage lockout (UVLO) protection on both the input and output supply rails. UVLO prevents the gate driver from outputting partial gate signals during supply power-up or brown-out, protecting the power switches from undefined operating states.
What package does the UCC21520DW use?
The UCC21520DW comes in a 16-SOIC (Small Outline Integrated Circuit) package with JESD-30 code R-PDSO-G16. This surface-mount package offers a compact footprint suitable for high-density PCB designs while maintaining sufficient creepage and clearance for reinforced isolation.
What types of power switches can the UCC21520DW drive?
The UCC21520DW is designed to drive both IGBTs and MOSFETs as a half-bridge based gate driver. Its standard input interface is compatible with PWM controllers operating at 3.3V or 5V logic levels, making it easy to integrate into existing power converter control architectures.
