LTC2933IDHD#PBF

LINEAR TECHNOLOGY  LTC2933IDHD#PBF  电压监控器, 低电平有效复位, 6监视器, 3.4V-13.9V输入, DFN-16

The is a programmable Hex Voltage Supervisor with two general purpose inputs. The EEPROM configurable voltage supervisor can simultaneously monitor up to six power supply voltage inputs. Each voltage detector offers programmable over-voltage/under-voltage 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.
