ADM1069ACP is a closed-loop limiting system with programmable reset generators, configurable output drivers, programmable function inputs, selectable attenuators, device controller, EEPROM and SMBus interface.
The ADM1069 is a configurable supervisory/sequencing device that offers a single-chip solution for supply monitoring and sequencing in multiple supply systems. It integrates a 12-bit ADC and four 8-bit voltage output DACs to implement closed-loop margining systems, allowing supply adjustment by altering the feedback node or reference of a DC/DC converter.
The device provides up to eight programmable inputs for monitoring under, over, or out-of-window faults on up to ten supplies. Eight programmable outputs can be used as logic enable outputs or to drive N-channel FETs. The logical core is a sequencing engine that implements state machine control of output drivers based on input events.
