MAX6872集成电路（IC）的监控器规格书PDF中文资料

General Description

The MAX6872/MAX6873 EEPROM-configurable, multi voltage supply sequencers/supervisors monitor several voltage detector inputs and four general-purpose logic inputs. The MAX6872/MAX6873 feature programmable outputs for highly configurable power-supply sequencing applications. The MAX6872 features six voltage detector inputs and eight programmable outputs, while the MAX6873 features four voltage detector inputs and five programmable outputs. Manual reset and margin disable inputs offer additional flexibility.
