General Description
The AAT4618 SmartSwitch is a member of
AnalogicTech's Application Specific Power MOS-
FET (ASPM) product family. It is a current lim-
ited P-channel MOSFET power switch designed for
high-side load switching applications operating with
inputs ranging from 2.4V to 5.5V, making it ideal for
2.5V, 3V, and 5V systems. An integrated current-
limiting circuit protects the input supply from large
currents which may cause the supply to fall out of
regulation. In addition, the AAT4618 thermal over-
load protection limits power dissipation and junction
temperatures associated with prolonged periods of
operation in current limit. Due to its low R
DS(ON)
, the
AAT4618 can be used to control loads that require
up to factory preset 400mA, 500mA, or 1A. The
ultra-fast current limit response to a sudden short
circuit is a mere 400ns which reduces the require-
ments of local supply bypassing. An open drain
FAULT flag signals an over-current or over-temper-
ature condition after a 4ms timeout. Quiescent cur-
rent is a low 10μA and the supply current decreas-
es to less than 1μA in shutdown mode.
The AAT4618 is available in a Pb-free 5-pin SOT-
23 or a 8-pin SC70JW package and is specified
over the -40°C to +85°C temperature range.
The AAT4600 series is a family of adjustable and
fixed voltage SmartSwitch products with a range of
current handling capabilities. Single versions with
adjustable current limit (AAT4610, AAT4601) or
fixed current limit (AAT4625) are available, as well
as dual versions with fixed current limit (AAT4626,
AAT4670).
