What are the key features of UCC21710DW?
- 5.7 kV RMS reinforced isolation rating meets IEC 60950 and IEC 62368 safety requirements for high-voltage industrial and EV inverter designs
- ±10 A peak sink/source current drives large-gate IGBT and SiC MOSFETs with fast turn-on/turn-off transitions to minimize switching losses
- Integrated desaturation (DESAT) detection and active Miller clamp enhance system protection and reduce false triggering in noisy environments
What is UCC21710DW used for?
The UCC21710DW is designed for three-phase inverters, DC-DC converters, and on-board chargers in electric vehicles and renewable energy systems requiring reinforced galvanic isolation. Its ±10 A drive capability and DESAT protection make it a natural fit for 650 V and 1200 V SiC MOSFET modules in solar string inverters and motor drives. Industrial UPS and traction applications also leverage the wide CMTI specification to maintain signal integrity in high dV/dt switching environments.

Frequently Asked Questions
What isolation voltage rating does UCC21710DW provide, and which safety standards does it satisfy?
The UCC21710DW achieves 5.7 kV RMS reinforced isolation, satisfying the creepage and clearance requirements of IEC 60950, IEC 62368, and VDE 0884-11. This rating is sufficient for 1500 V DC bus architectures in solar inverters and for the primary-to-secondary barrier in industrial SMPS designs compliant with functional safety level SIL 2.
How does the DESAT protection in UCC21710DW protect an IGBT during a short-circuit fault?
The desaturation detection circuit monitors the collector-emitter voltage of the IGBT after turn-on; if VCE exceeds the DESAT threshold (typically 9 V) for longer than the blanking time of about 500 ns, the UCC21710DW initiates a soft-shutdown within 2 µs. This controlled turnoff limits di/dt to safe levels, preventing the IGBT from experiencing destructive overcurrent events during hard short circuits.
For a 1200 V SiC MOSFET in a solar inverter, what peak gate current can UCC21710DW deliver to minimize switching losses?
The UCC21710DW sources and sinks ±10 A peak gate current, enabling turn-on and turn-off times under 100 ns for a 1200 V SiC MOSFET with 10 nC gate charge. Faster switching transitions reduce the cross-conduction interval and switching energy loss by up to 30% compared to a 4 A gate driver at the same gate resistor value.
How many output channels does UCC21710DW have, and when would a designer choose it over a dual-channel gate driver?
The UCC21710DW is a single-channel gate driver, targeting applications where each switch leg requires independent, isolated drive with dedicated fault protection. For a 3-phase inverter with 6 switches, 6 UCC21710DW devices provide fully independent DESAT and fault reporting per switch, whereas dual-channel drivers share fault lines and may complicate per-leg diagnostics in safety-critical designs.
