ADM1068ASTZ

Supervisors Overview

The ADM1068ASTZ is a Super Sequencer programmable supervisor sequencer integrated circuit designed for multi-power supply systems. It provides a single-chip solution for power monitoring and timing control, featuring up to eight programmable inputs for detecting under-voltage, over-voltage, or out-of-window faults across multiple rails. The device includes eight programmable outputs that function as logic enables or drive N-FET gates with voltages up to 12 V. Its core utilizes a state machine engine supporting up to 63 distinct states for flexible sequencing. Configuration data is stored in non-volatile EEPROM, allowing precise setup via official software tools.

Supervisors Feature Summary

• Configurable power monitoring and timing control engine using a state machine structure
• Eight programmable inputs for comprehensive fault detection across multiple voltage rails
• Eight programmable outputs capable of driving external N-FETs or serving as logic enables
• EEPROM-based configuration storage managed through dedicated graphical user interface software

Supervisors Applications

• Central office system power management
• Server and router power sequencing
• Multi-voltage system line card control
• DSP and FPGA power-up sequences
• Online testing of margin-adjusted power supplies

Supervisors Procurement Notes

Verify the exact ordering suffix against manufacturer documentation to ensure correct package type and tape/reel specifications. Confirm RoHS compliance status and lead time requirements directly with authorized distributors. Check for limited availability status as supply constraints may affect immediate procurement. Ensure compatibility with existing design-in software tools for configuration programming.

Supervisors Selection Notes

Select this component when designing systems requiring simultaneous monitoring of up to eight power rails with precise timing control. The internal charge pump supports high-side N-FET driving for power path integration. Consider the available input attenuation options for monitoring voltages up to 14.4 V on specific pins. Evaluate the need for the dedicated GUI programming tool during the design phase to configure the state machine effectively.

Supervisors Part Context

This part belongs to Analog Devices' Super Sequencer family, which specializes in complex power management solutions. It complements other supervisory devices by offering advanced state-machine capabilities rather than simple threshold monitoring. The series targets applications demanding strict power-up and power-down sequences to protect sensitive digital components from electrical stress.

Supervisors Replacement Considerations

The ADM1168ASTZ serves as a related controller within the same product family. Verify pinout compatibility and feature overlap before substitution. Ensure the replacement supports the required number of inputs and outputs for the specific application design.
