The AAT4644 is a four-channel resettable fuse. It utilizes independent current-limited and thermally protected P-channel MOSFETs to protect against short circuits. Each switch's 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. |
