Absolute Maximum RatingsPARAMETERRATING Supply Voltage IN –0.3V to 30V Supply Voltage OUT –30V to 30V Supply Voltage |IN – OUT| 30V Input Voltage SHDN –30V to 30V Output Voltage STATUS –0.3V to 30V Input Current IN 3A Output Current OUT –3A Operating Junction Temperature Range LT4423A –40°C to 125°C Storage Temperature Range –65°C to 150°C .1 All currents into pins are positive; all voltages are referenced to GND unless otherwise noted. 2 The LT4423 is tested under pulsed load conditions such that TJ ≈ TA. 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 The LT4423 includes overtemperature protection that is intended to protect the device during momentary overload conditions. Junction temperature will exceed 150°C when overtemperature protection is active. Continuous operation above the specified maximum operating junction temperature may impair device reliability. 4 Determined by design, not tested in production. 5 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 Load Switch with Load Sharing and Undervoltage Lockout Layout and Thermal Considerations Typical Applications High-Load Current Application Reverse Input Voltage Protection Related parts Outline Dimensions Ordering Guide
