TECHWORLD ·
✦ AI Summary
Mouser Electronics announced it will distribute Allegro MicroSystems' isolated SiC gate driver chipsets, AHV85003 and AHV85043.
Mouser said AHV85003 and AHV85043 are highly integrated isolated SiC gate drivers optimized for driving individual SiC FETs.
Applications include automotive on-board chargers (OBC), solar inverters, industrial robotics, data center power shelf, and general power supplies.
Mouser Electronics announced it will distribute Allegro MicroSystems' isolated SiC gate driver chipset. The products covered are "AHV85003" and "AHV85043."
"AHV85003" and "AHV85043" are highly integrated isolated SiC gate drivers. Mouser said the products help reduce system complexity, lower BOM, and address power conversion design challenges. It also said "AHV85003" and "AHV85043" are optimized for driving individual SiC FETs.
Applications for the chipsets include automotive on-board chargers (OBC), solar inverters, industrial robotics, data center power shelf, and general power supplies. Mouser said AHV85003 and AHV85043 help reduce complexity and BOM while supporting power conversion design.
The AHV85003 and AHV85043 isolated SiC gate driver chipsets distributed by Mouser use a Power-Thru design. This architecture simultaneously transmits PWM signals and bias power, eliminating the need for conventional bootstrap circuits and separate auxiliary bias power supplies.
The chipsets provide bipolar output from an adjustable negative voltage rail, supporting improved SiC FET turn-off and enhanced dv/dt immunity. They also feature separate 6A output gate pull-up pins and separate 6A output gate pull-down pins, supporting efficient high-frequency switching.
When used with the recommended external transformer, the chipsets can operate as self-powered isolated gate drive solutions. A range of third-party recommended transformers can also be used, and third-party transformers can be optimized based on drive voltage, gate charge, and isolation characteristics.
AHV85003 and AHV85043 are isolated SiC gate driver chipsets that have received AEC-Q100 Grade 1 certification, and their operating temperature range is -40 to 125°C. They include primary-side overtemperature protection and secondary-side overtemperature protection.
For use and evaluation, Allegro MicroSystems' two dedicated evaluation kits, APEK85003K18ES-02-MH and APEK85003K18ES-04-MH, are supported, and both evaluation kits can be purchased from Mouser.
