Additional Details:
The FAN7382G utilizes a floating channel design that allows for bootstrap operation, eliminating the need for a separate high-side power supply. The integrated under-voltage lockout (UVLO) circuit protects the MOSFETs/IGBTs from operating at insufficient gate voltage, and the over-current protection (OCP) feature helps prevent damage from excessive current flow. The matched propagation delay between the high-side and low-side channels ensures proper switching behavior and minimizes dead time. Detailed specifications, including voltage ratings, switching speeds, and timing parameters, are available in the manufacturer's datasheet. The IC is available in a variety of surface-mount packages.
