Prevent Reverse Charging of a Lithium Battery to Meet UL Safety Requirement APPLICATION NOTE
Lithium batteries are commonly used in many applications with devices requiring backup power, such as Real Time Clock (RTC) and memory devices.
Whenever lithium batteries are not the single power source in a circuit, there is risk of fire or explosion if the battery is accidentally connected with an electrical power source that would charge the battery.
This application note provides information needed for connecting Lithium batteries in backup power switching circuits such that the circuit meets Underwriters Laboratories (UL) standards. Specifically, UL standard 60950-1 describes the guidelines for Lithium batteries.
