Product details
Overview
ADM1060ARU-REEL7 from Analog Devices is a programmable supervisory/sequencing IC for multivoltage communications systems, featuring 7 independent supply fault detectors (1 high-voltage up to +14.4 V, 4 positive-only up to +6 V, 2 bipolar ±2 V to ±6 V), watchdog timeout programmable from 200 ms to 12.8 s, and 9 configurable programmable driver outputs (PDOs) with internal charge-pump high-drive capability for external N-channel FET gate control in server power sequencing.
For engineers reviewing the ADM1060ARU-REEL7 datasheet, ADM1060ARU-REEL7 pinout, ADM1060ARU-REEL7 application, or ADM1060ARU-REEL7 equivalent, key selection considerations include supply fault detection range flexibility, SMBus-programmable logic sequencing across 9 PDOs, EEPROM-persistent configuration, and dual-mode output drivers supporting both logic-level and high-voltage FET drive requirements in infrastructure network boards.
Technical Context
The ADM1060ARU-REEL7 implements a programmable logic block array (PLBA) with nine macrocells-each controlling one PDO-and supports combinatorial and time-delayed (0–500 ms per edge) sequencing logic using inputs from VH, VPn, VBn supply pins, WDI, and four GPIs. All seven supply fault detectors are independently configurable for undervoltage, overvoltage, or out-of-window detection with 8-bit DAC threshold programming and 5-bit hysteresis control.
It uses a VDD arbitration circuit that selects power from either VH (≥4.75 V) or any VPn (≥3.0 V), minimizing dropout to ~0.2 V via synchronous rectifier switching. The internal charge pump enables PDO1–PDO4 to deliver up to 14 V at 20 µA for driving external N-FET gates, while all nine PDOs support multiple pull-up configurations including internal weak (20 kΩ) or fast pull-ups to VDDCAP or VPn.

FAQ
What is the maximum supply voltage the ADM1060ARU-REEL7 can monitor on its VH pin?
The ADM1060ARU-REEL7 supports high-voltage supply fault detection up to +14.4 V on the VH pin, with absolute maximum rating of 17 V. Its VH input operates across 2 V to 14.4 V range and serves both as a fault detection channel and as a potential power source when ≥4.75 V-making ADM1060ARU-REEL7 suitable for monitoring legacy +12 V and newer high-voltage intermediate bus architectures.
Does the ADM1060ARU-REEL7 support negative supply monitoring?
Yes, the ADM1060ARU-REEL7 includes two dedicated bipolar supply fault detectors (VB1 and VB2) capable of monitoring negative supplies from –2 V to –6 V in negative mode, with ±1.5% factory-calibrated accuracy. These inputs cannot power the device but provide full rail integrity coverage for analog sections requiring dual-supply operation-confirming ADM1060ARU-REEL7's suitability for mixed-signal infrastructure boards.
How does the ADM1060ARU-REEL7 handle power supply arbitration during brownout conditions?
The ADM1060ARU-REEL7 uses an on-chip VDD arbitrator with synchronous rectifier switches to select power from the highest valid supply among VH (≥4.75 V) or VPn (≥3.0 V), minimizing dropout to ~0.2 V. During brownout, the VDDCAP decoupling capacitor (1 µF recommended) sustains internal logic while the arbitrator transitions to the next highest supply-ensuring continuous ADM1060ARU-REEL7 operation and reliable fault flag assertion throughout supply transients.
Can the ADM1060ARU-REEL7 drive external N-channel MOSFETs directly?
Yes, ADM1060ARU-REEL7 PDO1 through PDO4 feature an internally charge-pumped high-drive mode delivering up to 14 V at 20 µA-sufficient to fully enhance standard logic-level N-channel FETs used in high-side supply enable paths. This eliminates external level shifters and simplifies design of programmable, sequenced power rails-demonstrating ADM1060ARU-REEL7's role as an integrated power path controller.
Is EEPROM configuration retained after power cycling of the ADM1060ARU-REEL7?
Yes, the ADM1060ARU-REEL7 includes 256 bytes of dedicated EEPROM for storing all configuration data-including supply thresholds, hysteresis, glitch filter settings, PLBA logic definitions, and PDO drive modes-which automatically loads on power-up. With 100,000 write cycles and 10-year data retention at 55°C junction temperature, this ensures ADM1060ARU-REEL7 maintains validated sequencing behavior across field deployments without host intervention.
