LTC2936IUFD#PBF

LTC2936IUFD#PBF 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 (active-low MR), UV disable (active-low UVDIS), margin (active-low MARG), Write Protect (active-low 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 active-low ALERT or fault outputs. Faults can be configured with programmable delay-on-release times. Output type and polarity are also configurable. Applications include high availability computer systems, network servers, telecom equipment, data storage systems.
