Variable Parameters
• Factory setting of all Thresholds and Warning limits listed below are 100% of specified protection values.
• Variables can be written only when module is disabled with VHI < VHI_UVLO- and external bias (VDDB) applied.
• Module must remain in a disabled mode for 3ms after any changes to the variables below to allow sufficient time to commit changes to EEPROM.
