The AAT4644 is a four-channel resettable fuse. It utilizes independent current-limited and thermallyprotected P-channel MOSFETs to protect against short circuits. Current limit is factory programmed at 1A. Additional protection is provided with undervoltage lockout. The switches are turned off when the input voltage drops below a preset level. The quiescent supply current is typically 20A. The AAT4644 is a flexible solution, allowing system designers to gang outputs together for lower RDS(ON) and higher current limit.
