PRODUCT DATASHEET
AAT4901
FastSwitch
TM
General Description
The AAT4901 FastSwitch鈩?is a member of AnalogicTech鈥檚
Application Specific Power MOSFET鈩?(ASPM鈩? product
family. It is a full-bridge buffered power stage operating
with an input voltage range of 2.0V to 5.5V. The device
is designed to operate with a switching frequency of up
to 2MHz, minimizing the cost and size of external com-
ponents. The AAT4901 is protected from shoot-through
current by integrated break-before-make circuitry. The
drivers can be independently controlled and their propa-
gation delay, from input to output, is typically between
8ns-19ns dependent upon logic option.
Four options are offered providing a single input control,
dual input control or as two independent half-bridges.
Other features include low R
DS(ON)
and low quiescent cur-
rent allowing for high efficiency performance.
The AAT4901 is available in the space-saving, Pb-free
8-pin SC70JW package and is rated over the -40掳C to
+85掳C temperature range.
