6. Typical Chip Performance Parameters
Basic function test: HIN/HIN supports 3.3V/5V/15V level logic, VCC/VBS operating voltage can reach up to 20V, built-in CIN overcurrent protection function eliminates the need for an external comparator for overcurrent protection, simplifying customer PCB design. Equipped with fault output/FO function, enabling real-time overcurrent protection by connecting to MCU. Overcurrent protection recovery is achieved through FO_RST. The chip has a built-in active Miller clamp function to effectively prevent shoot-through caused by the Miller effect.
