ADM1067ACP

Supervisors Overview

The ADM1067ACP is a configurable supervisory and sequencing device designed for complex multi-supply systems. It integrates ten supply fault detectors, five selectable input attenuators, and six 8-bit voltage output DACs to enable open-loop margining. The device supports supervision of supplies up to 14.4 V on the VH pin and up to 6 V on VPn pins. It features ten programmable output drivers with various drive capabilities, including internal charge-pumped high drive for external N-FETs. A built-in sequencing engine implements state machine control, allowing power-up and power-down sequence management. Communication is handled via an SMBus interface.

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation to confirm package type and temperature range. Confirm RoHS compliance status through current datasheets. Check for obsolescence notices as this component may have limited availability. Ensure the specific ordering part number matches the required pinout and electrical specifications for your design.

Supervisors Selection Notes

Select this component when a single-chip solution for both supervision and sequencing is required. It is suitable for designs needing precise voltage monitoring across multiple rails with integrated margining capabilities. Consider the available output driver configurations and the need for SMBus control when evaluating alternatives. Verify that the input voltage ranges align with the system's supply requirements.

Supervisors Part Context

The ADM1067 belongs to a family of supervisory and sequencing devices from Analog Devices. It complements other PMIC solutions by offering integrated fault detection and sequencing logic. This part is distinct from pure ADCs or voltage references, focusing instead on system-level power management and control functions for complex electronic boards.

Supervisors Replacement Considerations

Check for direct replacements within the ADM106x series. Verify pin compatibility and functional equivalence before substituting. Review updated datasheets for any changes in electrical characteristics or package options.
