AAT4644 4-Channel Current Limited Load Switch General Description 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 20µA. The AAT4644 is a flexible solution, allowing system designers to gang outputs together for lower RDS(ON) and higher current limit. The AAT4644 is available in 8 pin TSSOP or SOP packages, specified over -40 to 85°C.
