DescripTion
The
LTC
®
2933
is an EEPROM configurable voltage super-
visor which can simultaneously monitor up to six power
supply voltage inputs. Each voltage detector offers I
2
C
programmable over/undervoltage thresholds in various
ranges and increments.
Two general purpose inputs (GPI) can be configured as
programmable manual reset (MR), UV disable (UVDIS),
margin (MARG) or auxiliary comparator (AUXC) inputs.
Three general purpose pins (GPIO) can be configured for
input or output operation. When configured as an input, a
GPIO pin can be mapped to any other GPIO configured as
output. The GPIO pins can also be configured as
ALERT
or fault outputs. Faults can be configured with program-
mable delay-on-release times. Output type and polarity
are also configurable.
Status and history registers log faults and can be polled
via the I
2
C interface. A fault snapshot is also backed up
in internal EEPROM. All parameters are programmable
via the I
2
C interface. Configuration EEPROM supports
autonomous operation without additional software.
