ISL73040SEH
ISL73040SEH is Radiation Hardened Low-Side GaN FET Driver manufactured by Intersil.
- Part of the ISL70040SEH comparator family.
- Part of the ISL70040SEH comparator family.
features an Undervoltage Lockout (UVLO) protection that ignores the inputs (IN/INB) and keeps OUTL turned on to ensure the Ga N 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 the ISL70040SEH and ISL73040SEH inputs to be connected directly to most PWM controllers. The ISL70040SEH and ISL73040SEH split outputs offer the flexibility to adjust the turn-on and turn-off speed independently by adding additional impedance to the turn-on/off paths.
The ISL70040SEH and ISL73040SEH operate across the military temperature range from -55°C to +125°C and are offered in an 8 Ld hermetically sealed ceramic Surface Mount Device (SMD) package or die form.
