Analog Devices Inc. ADM1060ARUZ-REEL7

Overview

ADM1060ARUZ-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 charge-pump high-drive capability for external N-channel FETs. It enables controlled power-up sequencing in central office systems and high-density infrastructure boards.

For engineers reviewing the ADM1060ARUZ-REEL7 datasheet, ADM1060ARUZ-REEL7 pinout, ADM1060ARUZ-REEL7 application, or ADM1060ARUZ-REEL7 equivalent, key selection considerations include supply fault detection range per input type (VH/VPn/VBn), SMBus-programmable logic block array (PLBA) sequencing flexibility, PDO output modes (open-collector, internal pull-up, charge-pump), EEPROM configuration persistence, and thermal performance in TSSOP-28 package at −40°C to +85°C.

Technical Context

The ADM1060ARUZ-REEL7 implements a programmable logic block array (PLBA) composed of nine macrocells-each controlling one PDO-with combinational and sequential logic routing across all inputs (7 SFDs, WDI, 4 GPIs). Inputs feed into configurable comparators with 8-bit DAC-programmed UV/OV thresholds, digitally adjustable hysteresis (5-bit), and glitch filtering (0–100 µs).

Power arbitration selects VDDCAP from the highest valid supply among VH (≥4.75 V) or VPn (≥3.0 V), using synchronous rectifier circuitry to minimize dropout (~0.2 V). Charge-pump circuitry on PDO1–PDO4 delivers up to 14 V at 20 µA for driving external N-FET gates, while all PDOs support programmable delays (0–500 ms) on rising/falling edges via dedicated delay blocks.

FAQ

What voltage ranges does the ADM1060ARUZ-REEL7 support for supply fault detection?

The ADM1060ARUZ-REEL7 supports three distinct input types: VH pin accepts 2 V to 14.4 V for high-voltage monitoring; VP1–VP4 pins handle 0.6 V to 6 V positive-only supplies; VB1 and VB2 pins detect bipolar supplies from −6 V to −2 V or +1 V to +6 V, with polarity selected per register. Absolute maximum ratings are 17 V on VH, 7 V on VP, and ±7 V on VB pins.

How does the ADM1060ARUZ-REEL7 handle power arbitration among multiple supplies?

The ADM1060ARUZ-REEL7 uses an internal VDD arbitrator that selects the highest valid supply between VH (≥4.75 V) and VPn (≥3.0 V) pins, employing synchronous rectifier circuitry to minimize voltage drop (~0.2 V). The VBn pins cannot power the device. A 1 µF capacitor on VDDCAP provides reservoir hold-up during brownouts, maintaining operation until the next highest supply takes over.

Can the ADM1060ARUZ-REEL7 drive external N-channel FETs directly, and if so, which pins support this?

Yes-the ADM1060ARUZ-REEL7 supports direct gate drive of external N-channel FETs via its charge-pump circuitry on PDO1 through PDO4. In high-voltage mode, these outputs deliver 11 V to 14 V at 20 µA, sufficient to fully enhance common logic-level N-FETs. This capability is exclusive to PDO1–PDO4; PDO5–PDO9 operate only in standard digital output modes.

What is the role of the programmable logic block array (PLBA) in the ADM1060ARUZ-REEL7?

The PLBA in the ADM1060ARUZ-REEL7 consists of nine macrocells-one per PDO-that implement wide AND logic to combine any input (SFDs, GPIs, WDI, other PDOs) into custom sequencing or combinatorial conditions. Each macrocell output feeds a programmable delay block (0–500 ms on rising/falling edges), enabling precise, conditional power-up sequences-such as requiring three supplies to stabilize before asserting a fourth PDO.

Does the ADM1060ARUZ-REEL7 retain its configuration after power cycling?

Yes-the ADM1060ARUZ-REEL7 contains 256 bytes of dedicated EEPROM that stores all configuration settings (thresholds, hysteresis, glitch filters, PLBA logic, delays). This configuration auto-loads on power-up, ensuring consistent behavior without host initialization. An additional 256 bytes are available for user-defined system data such as date codes or board IDs, accessible via the same SMBus interface.
