Description

This User's Guide describes the characteristics, operation and use of the UCC21732QDWEVM-025 Evaluation Module (EVM). This TI EVM provides driving and protection for popular Silicon Carbide (SiC) MOSFETs and Si IGBTs both in discrete and Power Module implementations. The EVM is using feature rich isolated driver device UCC21732 that is part of family of UCC217XX drivers. A complete schematic diagram, printed-circuit board layouts, and bill of materials are included in this document.

Features

  • 10-A peak split sink/source drive current for fast turn ON and turn OFF time
  • 2-W bias supply with UVLO and OVLO protection set by default at 4.5 V to 5.5 V
  • Drive voltages by default are 17/-5 V with single 5-V input supply
  • Drive voltages can be also programmed independently from 11 V to 19 V for turn ON and from -3.3 V to -6 V for turn OFF by using two input supplies from 3.3 V to 5.5 V
  • Noise-immune design with CMTI >150 V/ns
  • 5.7-kVrms reinforced isolation
  • OC short-circuit shunt resistor sensing with two-level (UCC21732) or single level (UCC21710) soft turn-OFF protection

Typical applications

  • Solar inverters, Motor drives, HEV/EV chargers
