EVALUATION KIT AVAILABLE MAX14714 Compact 6A Smart Power Path Selector General Description Features and Benefits The MAX14714 compact 6A smart power path selector fea- Provides Robust Bidirectional Power Path tures a low, 11m (typ) R internal FET and provides the Wide Operating Input Voltage: +1.6V to +5.5V ON system power from two separate power sources. The device 6A Continuous Current Capability Integrated Two 11m (typ) MOSFET Switches has two switches in SPDT configuration, with bidirectional current-blocking capability when the switch is off. Enables Simple Power Switch Design The MAX14714 features two individual enable inputs to Individual Path Control control each power path. Each enable input controls the Automatic Power Path Control corresponding path as an independent switch. However, Automatic Soft-Start when both paths are enabled, the internal comparator Powered by IN1, IN2, or OUT controls the path based on the voltage at input nodes. Significantly Extends Battery Life The device also features an ultra-low supply current in the Ultra-Low Quiescent Supply Current 2.5A (typ) operating or off states for longer battery-life. Fast Switchover The device is available in a 15-bump (1.2mm x 2.0mm) Optimum Soft-Start Feature wafer-level package (WLP) and operates over the -40C Compact Package Saves Board Space to +85C extended temperature range. 15-Bump 1.2mm x 2.0mm WLP Applications Smartphones Ordering Information appears at end of data sheet.

Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Electrical Characteristics (V , V = 1.6V to 5.5V T = -40C to +85C, unless otherwise noted.
