The LTC2933 is an EEPROM configurable voltage supervisor which can simultaneously monitor up to six power supply voltage inputs. Each voltage detector offers I2C 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 programmable delay-on-release times. Output type and polarity are also configurable.

Status and history registers log faults and can be polled via the I2C interface. A fault log snapshot is also backed up in internal EEPROM. All parameters are programmable via the I2C interface. Configuration EEPROM supports autonomous operation without additional software.

Product Detail

The DC1633B is a demonstration system that showcases the LTC2933, a 6-channel I2C/SMBus voltage supervisor with EEPROM. The LTC2933 simultaneously monitors up to six power supply voltages and detects under/overvoltage conditions. In addition the LTC2933 monitors two GPI pins and is able to drive three GPIO pins to indicate OV, UV, system reset, system alert, or other control signal.
