The junction temperature (TJ in °C) is calculated from the ambient temperature (TA in °C) and power dissipation (PD in Watts) according to the formula: TJ = TA + (PD • θJA). 3 This voltage is set by the power path MOSFET’s body diode and will safely exceed 0.3V during start-up for a limited time determined by the body diode thermal dissipation. 4 Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, functional operation of the product at these or any other conditions above those indicated in the operational section of this specification is not implied. Operation beyond the maximum operating conditions for extended periods may affect product reliability. analog.com Rev. 0 4 of 18 Document Outline Features Applications General Description Simplified Application Diagram TABLE OF CONTENTS Revision History Specifications Absolute Maximum Ratings Pin Configurations and Function Descriptions Typical Performance Characteristics Block Diagram Theory of Operation Applications Information USB PD 3.0 and Back-Up Battery Supply Automatic Power Path Control 5V Power Ride-Through High-Voltage Diode-OR Layout and Thermal Considerations Typical Application High-Load Current Application Reverse Input Voltage Protection Related Parts Outline Dimensions Ordering Guide
