MAX20320

Smart, Compact, 6A, Power-Path Selector with Reset Control

Provides the system power from two separate power sources with ultra-low supply current


Please check latest availability status for a specific part variant.

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 system 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 active-low MR1, active-low MR2, and TAIN.

The devices feature two individual enable inputs to control each power path. The MAX14740 enable function is provided through I2C 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 × 2.1mm) wafer-level packages (WLPs) and operate over the -40°C to +85°C extended temperature range.
