The AAT4612 SmartSwitch™ is a member of AnalogicTech's Application Specific Power MOSFET™ (ASPM™) product family. It is a Current Limited P-channel MOSFET power switch designed for high-side load-switching applications operating with inputs ranging from 2.4V to 5.5V which makes it ideal for both 3V and 5V systems. An integrated current- limiting circuit protects the input supply from large currents which potentially cause the supply to fall out of regulation. In addition, the AAT4612 thermal overload protection limits power dissipation and junction temperatures associated with prolonged periods of operation in current limit. Due to its low RDS(ON), the AAT4612 can be used to control loads that require up to 1A even while operating at high ambient temperatures.
The ultra fast current-limit response to a sudden short circuit is a mere 500ns which reduces the requirements of local supply bypassing. Quiescent current is a low 10µA and in shutdown mode, the supply current decreases to less than 1µA.
The AAT4612 is available in a 5-pin SOT23, and an 8-pin SC70JW specified over a -40 to 85°C temperature range.
The AAT4600 Series is a family of adjustable and fixed SmartSwitch™ products with a range of current handling capabilities. Available are single versions with adjustable current limit (AAT4610, AAT4601) as well as fixed current limit (AAT4625), and dual versions with fixed current limit (AAT4626, AAT4670).
