Overview
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.
