Glossary of terms
The following list contains terms used throughout the
document.
AUXC – Auxiliary Comparator. A GPI pin may be pro-
grammed to this function and map behavior to a GPIO
pin. Nominal V
= 0.5V.
TH
EEPROM – Non-volatile memory (NVM) storage used to
retain data after power is removed.
Margin – Term used typically in board level testing that
increases/decreases the output voltage to look for sensi-
tivity/marginality problems.
MARG – Ignore margining (OV and UV) when active (low).
A GPI pin may be programmed to this function and map
behavior to a GPIO pin. Nominal V

MR – Manual Reset, Active Low. A GPI pin may be pro-
grammed to this function and map behavior to a GPIO pin,
and optionally clear the fault history. Nominal V
NVM – Non-volatile memory, see EEPROM.
OV – Overvoltage, the result of a voltage comparison that
a pin voltage is above a programmable threshold voltage.
Rail – The final output voltage that the LTC2936 supervises.
Supervise – The act of quickly responding (compared to
a fault setting) to a voltage condition that is compared to
pre-programmed values.
UV – Undervoltage, the result of a voltage comparison that
a pin voltage is below a programmable threshold voltage.
UVDIS – UV Disable. Ignore UVs when the pin is low. A
GPI pin may be programmed to this function and map
behavior to a GPIO pin. Nominal V
