Description

The MAX14714 compact 6A smart power path selector features a low, 11mΩ (typ) RON internal FET and provides the system power from two separate power sources. The device has two switches in SPDT configuration, with bidirectional current-blocking capability when the switch is off.

The MAX14714 features two individual enable inputs to control each power path. Each enable input controls the corresponding path as an independent switch. However, when both paths are enabled, the internal comparator controls the path based on the voltage at input nodes. The device also features an ultra-low supply current in the operating or off states for longer battery-life.

The device is available in a 15-bump (1.2mm x 2.0mm) wafer-level package (WLP) and operates over the -40°C to +85°C extended temperature range.
