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.
Current limit is factory programmed at 1A.
Additional protection is provided with under-voltage 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 a Pb-free, 8-pin TSSOP or SOP package and is specified over the -40°C to +85°C temperature range.
