Description
DATASHEET ISL70040SEH, ISL73040SEH Radiation Hardened Low-Side GaN FET Driver The ISL70040SEH and ISL73040SEH are low-side drivers designed to drive .
Features
* an Undervoltage Lockout (UVLO) protection that ignores the inputs (IN/INB) and keeps OUTL turned on to ensure the GaN FET is in an OFF state whenever VDRV is below the UVLO threshold. The ISL70040SEH and ISL73040SEH inputs can withstand voltages up to 14.7V regardless of the VDD voltage. This allows
Applications
* Flyback and forward converters
* Boost and PFC converters
* Secondary synchronous FET drivers
