MAX6870ETJ集成電路（IC）的監(jiān)控器規(guī)格書PDF中文資料

General Description

The MAX6870/MAX6871 EEPROM-configurable, multi voltage supply sequencers/supervisors monitor several voltage detector inputs, two auxiliary inputs, and four general-purpose logic inputs. The MAX6870/MAX6871 feature programmable outputs for highly configurable power-supply sequencing applications. The MAX6870 features six voltage detector inputs and eight programmable outputs, while the MAX6871 features four voltage detector inputs and five programmable outputs. Manual reset and margin disable inputs offer additional flexibility.
