Texas Instruments UCC21710 | Demoboard UCC21710QDWEVM-025
Driving and protection evaluation board for SiC and IGBT transistors and power modules
Overview
| Topology | Push-Pull Converter symmetrical isolated |
| Input voltage | 5 V |
| Output 1 | 17 V / 10 A |
Description
The UCC21710QDWEVM-025 is a compact, single channel isolated gate driver board providing drive, bias voltages, protection and diagnostic needed for SiC MOSFET and Si IGBT Power Modules housed in 150 x 62 x 17 mm and 106 x 62 x 30 mm packages. This TI EVM is based on 5.7-kVrms reinforced isolation drivers UCC21710 in SOIC-16DW package with 8.0 mm creepage and clearance. The EVM includes SN6505B based isolated DC-DC transformer bias supplies.
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 Vto -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) softturn-OFF protection
- OC signal setting either for positive or negative polarity
- Desat short-circuit sensing for UCC21750
- Active Miller clamp using external FET (UCC21732) or internal (UCC21710)
- Output short circuit clamp
- Fault feedback with reset
- Isolated temperature and input rail monitoring
Typical applications
- Solar inverters, Motor drives, HEV/EV chargers, HEV/EV traction Inverters
