ADM1062ASUZ

Supervisors Overview

The ADM1062ASUZ is a Super Sequencer integrated circuit manufactured by Analog Devices Inc., designed for complex supply monitoring and sequencing in multi-supply systems. It features a 40-lead LFCSP package, operates within a voltage range of 2.7 V to 14.4 V, and supports ten monitored inputs with thresholds from 573 mV to 14.4 V. The device includes a watchdog timer, manual reset capability, and an auxiliary 12-bit ADC alongside six 8-bit DACs for margining control.

Supervisors Feature Summary

• Integrates supervisory sequencing with closed-loop margining capabilities via built-in DAC outputs
• Provides comprehensive power management through ten monitored input channels and configurable thresholds
• Includes an auxiliary 12-bit analog-to-digital converter for system temperature and voltage monitoring

Supervisors Applications

• Servers and routers
• DSP/FPGA supply sequencing
• Central office systems
• Multivoltage system line cards
• In-circuit testing of margined supplies

Supervisors Procurement Notes

Verify the specific suffix ASUZ corresponds to the tape-and-reel packaging variant when sourcing. Confirm RoHS compliance status and lead time restrictions directly with authorized distributors or Analog Devices, as availability may be limited. Ensure the operating temperature range meets the application requirements before finalizing procurement.

Supervisors Selection Notes

Select this component for applications requiring precise multi-rail sequencing and active margining control. The integrated ADC and DACs allow for closed-loop regulation adjustments without external components. Consider the LFCSP-40 footprint and pin count against board space constraints and thermal dissipation needs during the design phase.

Supervisors Part Context

Part of the ADM1062 series, which offers configurable supervisory and sequencing functions. This series is designed to replace discrete supervisor circuits, reducing bill-of-materials complexity. It complements other devices like the ADM1063 and ADM1066 within the Super Sequencer family, providing scalable solutions for various power architecture complexities.

Supervisors Replacement Considerations

Check for direct pin-compatible upgrades within the ADM106x family. Verify if the ADM1066 provides necessary feature parity regarding margining controls. Review datasheet revisions for any functional updates that might affect existing designs.
