- Page 2 SNVU493 – October 2015 Introduction The Texas Instruments LM8365EVM evaluation module (EVM) helps designers evaluate the operation and performance of the LM8365 Micropower Undervoltage Supervisor with Programmable Output Delay. For this EVM, the 2.7 V reset threshold LM8365 will be used. The EVM demonstrates proper functionality of the LM8365 via selection of 3 distinct capacitors corresponding to programmable delay times.
