The LTC2936 is an EEPROM configurable voltage supervisor which can simultaneously monitor up to six power supply voltage inputs. Each voltage detector offers I2C programmable overvoltage/undervoltage thresholds in various ranges and increments and a dedicated comparator output.

Two general purpose inputs (GPI) can be configured as programmable manual reset (MR), UV disable (UVDIS), margin (MARG), Write Protect (WP) 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 snapshot is also backed up in internal EEPROM. All parameters are programmable via the I2C interface. Configuration EEPROM supports autonomous operation without additional software.
