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 VTH = 0.5V.

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 VTH = 1.0V.

Glossary of terms

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 VTH = 1.0V.

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–ThefinaloutputvoltagethattheLTC2936supervises.

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 VTH = 1.0V.
