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 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 OV and UV faults when active (low). A GPI

pinmaybeprogrammedtothisfunctionandmapbehavior

to a GPIO pin. Nominal VTH = 1.0V.

MR: Manual Reset, Active Low. A GPI pin may be pro-

grammed to this function, 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:ThefinaloutputvoltagethattheLTC2933supervises.

Supervise: The act of quickly responding (compared

to a fault setting) to a voltage 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 UV faults 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.
