AOZ1342
Dual Channel USB Switch
General Description
The AOZ1342 power-distribution switches is intended
for applications where heavy capacitive loads and
short-circuits are likely to be encountered. This device
incorporates N-channel MOSFET power switches for
power-distribution systems that require multiple power
switches in a single package. Each switch is controlled
by a logic enable input. Gate drive is provided by an
internal charge pump designed to control the power-switch
rise times and fall times to minimize current surges
during switching. The charge pump requires no external
components and allows operation from supplies as low
as 2.7 V.
The AOZ1342 offers 1.5 A of maximum continuous
current.
The AOZ1342 is available in an Exposed Pad SO-8
package and is rated over a -40 °C to +85 °C ambient
temperature range.
