Page 8 of datasheet, it states:
16 VBAT Backup Power-Supply Input. If VBAT is not used, connect to ground. Diodes placed in series between the VBAT pin and the battery can cause improper operation. UL recognized to ensure against reverse charging when used with a lithium battery. Go to www.maximintegrated.com/qa/info/ul.
Can you elaborate about diodes placed in series between the VBAT pin and the battery can cause improper operation?
I'm curious to know exactly what your engineers are concerned about and perhaps what improper operation was witnessed.
Thank you, -Mark.
