MAX14740–MAX14742/
MAX20320
Smart, Compact, 6A, Power-Path
Selector with Reset Control
General Description
The MAX14740—MAX14742/MAX20320 compact 6A
smart power-path selector with reset control features a
low 11mΩ (typ) RON internal FET and provides the sys-
tem power from two separate power sources. The devices
feature reset and disconnect functions to provide system
power, reset, and disconnect based on multiple inputs,
including
MR1, MR2,
and TAIN.
The devices feature two individual enable inputs to control
each power path. The MAX14740 enable function is
provided through I
2
C control, while those of the MAX14741/
MAX14742//MAX20320 are performed by GPIO control.
Each enable input controls the corresponding path as
an independent switch. However, when both paths are
enabled, the device can either autoselect the input source
or have both inputs connected to the output. When autoselect is
chosen, the internal comparator controls the path based
on the voltage at the input nodes. The devices also
feature an ultra-low supply current, even during an operating
state or off state, providing longer battery life.
The devices are available in 20-bump (1.6mm x 2.1mm)
wafer-level packages (WLPs) and operate over the -40°C
to +85°C extended temperature range.
