Product details
Overview
ADM1062ASUZ-REEL7 from Analog Devices is a configurable supervisory and sequencing IC for multivoltage systems, integrating 10-supply fault detection (±1% accuracy), 12-bit ADC voltage readback, six 8-bit DACs for closed-loop margining (0.300 V–1.551 V), internal/remote temperature sensing, and a state-machine-based sequencing engine with 63 programmable states. It supports DSP/FPGA supply sequencing in telecom line cards.
For engineers reviewing the ADM1062ASUZ-REEL7 datasheet, ADM1062ASUZ-REEL7 pinout, ADM1062ASUZ-REEL7 application, or ADM1062ASUZ-REEL7 equivalent, key selection criteria include VH/VPx input voltage supervision ranges (up to 14.4 V), charge-pumped high-voltage PDO outputs (up to 14 V), SMBus programmability, EEPROM configuration storage, and dual-mode temperature measurement.
Technical Context
The ADM1062ASUZ-REEL7 implements a deterministic state-machine sequencing engine with conditional transitions triggered by input events (e.g., supply OK, fault, timer expiry), enabling precise power-up/down control and fault-handling logic across up to 10 rails. Its 12-bit SAR ADC digitizes attenuated VH, VPx, and VXx inputs with ±2.5 LSB INL and 0.44 ms per conversion.
Margining is implemented via six buffered 8-bit DACs with 2.36 mV LSB step size, programmable center points (0.6–1.25 V ranges), and 50 pF load settling in 2 μs. The device uses an on-chip arbitration circuit to select VDDCAP from the highest of VH (3.0–14.4 V) or VPx (3.0–6.0 V), ensuring operation down to 3.0 V with 2.7–5.4 V regulated output.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VH Input Range | 3.0 V to 14.4 V - supports supervision of high-voltage rails including 12 V and 5 V system supplies without external attenuation. |
| VPx Input Range | 1.25 V to 6.0 V - selectable attenuation enables accurate monitoring of core logic rails (1.2 V, 1.8 V, 2.5 V, 3.3 V, 5 V). |
| ADC Resolution | 12-bit - provides 0.125°C temperature resolution and <0.5% voltage readback accuracy across full range. |
| DAC Output Range | 0.300 V to 1.551 V - enables closed-loop margining of dc-dc converter feedback nodes for production test and dynamic voltage tuning. |
| PDO High-Voltage Mode | Up to 14 V output (PDO1–PDO6) - drives N-FET gates directly for high-side supply enable/control without external level shifters. |
| SMBus Interface | 400 kHz compliant - allows real-time reconfiguration of sequencing states, fault thresholds, and DAC values in-system. |
| Temperature Sensing | ±3°C local + ±3°C remote diode - supports board-level thermal management and hot-spot monitoring in servers/routers. |
Pinout & Package
ADM1062ASUZ-REEL7 is packaged in a 40-lead, 6 mm × 6 mm LFCSP with exposed pad (NC). Power is derived from VH or VPx pins; VDDCAP is internally regulated to 4.75 V. All ground pins (GND, AGND, REFGND, PDOGND) must be connected together in layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VH, VP1–VP4, VX1–VX5 | Supply fault detector inputs | High-impedance analog inputs with programmable attenuation; VH supports up to 14.4 V, VPx up to 6.0 V, VXx up to 1.375 V. |
| PDO1–PDO10 | Programmable driver outputs | PDO1–PDO6 support charge-pumped HV mode (12 V typical); PDO7–PDO10 are LV push-pull/open-collector outputs. |
| DAC1–DAC6 | Voltage output DAC terminals | Buffered 8-bit outputs; default high-impedance at power-up; settle in 2 μs with 50 pF load. |
| SDA, SCL, A0, A1 | SMBus interface and address pins | Standard 2-wire bus; A0/A1 set 7-bit slave address (default 0x2C); open-drain with external pull-ups required. |
| DN, DP | Remote temperature sensor interface | Differential input for external thermal diode; 200 μA current source enables accurate remote junction measurement. |
| REFIN, REFOUT | ADC reference input/output | REFOUT = 2.048 V ±0.25%; REFIN accepts internal REFOUT or external precision reference for improved ADC gain accuracy. |
Key Features
| Feature | Design Value |
|---|---|
| 10-supply supervision with <1.0% accuracy | Enables reliable fault detection across mixed-voltage systems (1.2 V core, 3.3 V I/O, 12 V aux) without calibration drift over temperature. |
| 63-state sequencing engine | Supports complex conditional logic (e.g., delay until VP1 OK → assert PDO1 → wait for VX2 OK → assert PDO2) for FPGA/DSP boot sequences. |
| Closed-loop voltage margining | Uses DAC outputs to adjust dc-dc converter feedback nodes in real time, enabling automated in-circuit test at ±5% supply deviation. |
| Internal + remote temperature sensing | Combines on-die sensor (±3°C) with differential diode interface (±3°C) to monitor both IC junction and remote hot spots (e.g., CPU, VRM). |
| User EEPROM (256 bytes) | Stores full configuration (sequencing states, thresholds, DAC settings) for autonomous operation after power cycle-no host intervention needed. |
Applications
| Telecom Line Cards | Server Power Management |
|---|---|
Use Scenario: Multirail power delivery for line card ASICs requiring strict sequencing between 12 V, 5 V, 3.3 V, 1.8 V, and 1.2 V supplies. IC Role / Device Role / Timing Role: Central sequencing supervisor that monitors all rails, asserts enable signals in order, and halts boot on first fault.

Equivalent & Alternatives
The following parts are listed as comparable options for similar supervisory and sequencing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM1066ARUZ-REEL | 12-supply supervision, no integrated DACs, identical sequencing engine and SMBus interface. | Lacks closed-loop margining capability; requires external DAC for voltage adjustment. | Select when only sequencing/supervision is needed and margining is handled externally or not required. |
| TPS40422RGET | Two-phase PWM controller with integrated sequencing logic but no ADC/DAC or temperature sensing. | Designed for active regulation-not supervision; no voltage readback or margining functions. | Select when replacing a dc-dc controller with built-in sequencing, not when adding supervisory intelligence to existing regulators. |
Compared with ADM1062ASUZ-REEL7, ADM1066ARUZ-REEL offers higher channel count but omits margining, while TPS40422RGET integrates power conversion but lacks monitoring and test features-making ADM1062ASUZ-REEL7 uniquely suited for post-regulator supervision and production validation.

FAQ
What is the primary function of the ADM1062ASUZ-REEL7?
The ADM1062ASUZ-REEL7 is a configurable supervisory and sequencing IC that monitors up to 10 voltage rails with ±1% accuracy, sequences power-up/down via a 63-state engine, performs closed-loop voltage margining using six 8-bit DACs, and measures temperature via internal and remote sensors. It operates autonomously using configuration stored in its 256-byte EEPROM.
Does the ADM1062ASUZ-REEL7 support high-voltage FET gate driving?
Yes, the ADM1062ASUZ-REEL7 supports high-voltage gate driving through PDO1–PDO6, which feature an internal charge pump capable of delivering up to 14 V (typical 12 V) to drive N-channel FETs in high-side supply paths. This eliminates the need for external level shifters or gate drivers in many applications.
How does the ADM1062ASUZ-REEL7 handle power supply redundancy?
The ADM1062ASUZ-REEL7 uses an internal arbitration circuit to derive VDDCAP from the highest valid voltage among VH (3.0–14.4 V) or VPx (3.0–6.0 V) pins. This ensures continuous operation even if one supply fails, and the 0.2 V dropout enables functionality down to 3.0 V input-critical for redundant telecom and server power systems.
Can the ADM1062ASUZ-REEL7 perform in-circuit voltage margining tests?
Yes, the ADM1062ASUZ-REEL7 is explicitly designed for in-circuit testing: its six DACs inject precise offsets into dc-dc converter feedback nodes, while its 12-bit ADC reads back actual rail voltages. This closed-loop system verifies board functionality at ±5% supply deviations without external test equipment.
What package type is used for the ADM1062ASUZ-REEL7?
The ADM1062ASUZ-REEL7 is supplied in a 40-lead, 6 mm × 6 mm LFCSP (Lead Frame Chip Scale Package) with exposed pad (NC). The exposed pad improves thermal and mechanical stability but must not be electrically connected-it is a no-connect terminal per Analog Devices' datasheet.
