Product details

Overview

ADM1063ACPZ-REEL7 from Analog Devices is a multisupply supervisory and sequencing IC with integrated 12-bit ADC, temperature monitoring (1 internal + 2 remote diode sensors), and 10 programmable driver outputs (PDOs). It supports up to 10 supply rails with <0.5% supervision accuracy at 25°C, 5 selectable input attenuators for VH/VPx inputs, and charge-pumped high-voltage drive (up to 14 V) on PDO1–PDO6 for N-FET gate control - used in FPGA/DSP power-up sequencing and voltage margining.

For engineers reviewing the ADM1063ACPZ-REEL7 datasheet, ADM1063ACPZ-REEL7 pinout, ADM1063ACPZ-REEL7 application, or ADM1063ACPZ-REEL7 equivalent, key selection considerations include its 40-lead 6 mm × 6 mm LFCSP package, SMBus interface, dual-mode PDO output configuration (open-collector/push-pull/charge-pump), round-robin ADC readback of 12 channels, and sequencer state-machine support for complex fault-handling and power-down logic.

Technical Context

The ADM1063ACPZ-REEL7 implements a deterministic state-machine-based Sequencing Engine (SE) supporting up to 63 states, enabling conditional transitions based on input events (e.g., supply OK, overtemperature, watchdog timeout). Its 12-bit SAR ADC performs simultaneous voltage readback across VH, VP1–VP4, VX1–VX5, REFIN, and temperature sensor channels with 0.44 ms per conversion and ±2.5 LSB INL.

Power arbitration selects the highest valid supply among VH (3.0–14.4 V) or VPx (3.0–6.0 V) to generate a regulated 4.75 V VDDCAP output; no external regulator is needed. The device integrates a 2.048 V reference (±0.25%) with 60 dB PSRR, and supports closed-loop voltage margining on six rails using programmable DAC-controlled feedback injection.

Equivalent & Alternatives

The following parts are listed as comparable options for similar multisupply supervisory and sequencing applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ADM1062ACPZ-REEL7	9-supply supervision (vs. 10), no charge-pump HV PDOs; only push-pull/open-collector outputs	Lacks N-FET gate drive capability; requires external level shifters for >5 V enable signals	Select when system uses only ≤9 rails and all enables are logic-level (≤3.3 V/5 V)
TPS40400RHLR	6-supply supervision, no integrated ADC or temperature sensing; dedicated PMBus interface	Optimized for DC/DC controller coordination, not general-purpose voltage monitoring or margining	Prefer for tightly coupled POL regulator systems where telemetry is handled by controller, not standalone supervision

Compared with ADM1062ACPZ-REEL7 and TPS40400RHLR, the ADM1063ACPZ-REEL7 uniquely combines 10-rail supervision, charge-pump HV drive, 12-bit ADC telemetry, and dual thermal sensing in one LFCSP package - making it the only option for compact, self-contained sequencing in high-density FPGA or server applications requiring margining and thermal awareness.

FAQ

What is the primary function of the ADM1063ACPZ-REEL7 in a power system?

The ADM1063ACPZ-REEL7 serves as a fully autonomous multisupply supervisory and sequencing controller. It monitors up to 10 voltage rails with <0.5% accuracy, executes programmable power-up/down sequences via its 63-state sequencing engine, drives external FETs using charge-pumped PDOs, and provides telemetry via its 12-bit ADC and temperature sensors - all without requiring host processor intervention. The ADM1063ACPZ-REEL7 replaces discrete supervisors, timers, and level shifters in high-reliability systems.

Does the ADM1063ACPZ-REEL7 support voltage margining, and how is it implemented?

Yes, the ADM1063ACPZ-REEL7 provides complete closed-loop voltage margining for six voltage rails. It uses its internal 12-bit DACs to inject controlled current into feedback nodes of DC/DC converters, while simultaneously measuring resulting rail changes via its 12-bit ADC. Margining is fully programmable through SMBus registers and stored in the 256-byte EEPROM, enabling automated in-circuit testing and production validation. This functionality is integral to the ADM1063ACPZ-REEL7 design and does not require external components.

What are the key differences between the ADM1063ACPZ-REEL7 and the ADM1062ACPZ-REEL7?

The ADM1063ACPZ-REEL7 supports 10-supply supervision versus 9 on the ADM1062ACPZ-REEL7, and includes charge-pump high-voltage PDOs (PDO1–PDO6) capable of driving N-FET gates up to 14 V - a feature absent in the ADM1062ACPZ-REEL7, which offers only push-pull and open-collector outputs. Additionally, the ADM1063ACPZ-REEL7 integrates dual remote temperature sensor inputs (D1P/D1N, D2P/D2N), whereas the ADM1062ACPZ-REEL7 lacks remote thermal sensing. These capabilities make the ADM1063ACPZ-REEL7 suitable for more demanding FPGA and server applications.

Can the ADM1063ACPZ-REEL7 operate with a 12 V backplane supply, and how is it powered?

Yes, the ADM1063ACPZ-REEL7 supports direct connection to a 12 V backplane supply via its VH pin, which accepts inputs up to 14.4 V. The device uses internal power arbitration to select the highest valid supply among VH or VPx pins (minimum 3.0 V) and regulates it to a stable 4.75 V VDDCAP output. This architecture eliminates the need for an external LDO and ensures continued operation even if one supply fails - a key reliability feature of the ADM1063ACPZ-REEL7 in redundant systems.

How does the ADM1063ACPZ-REEL7 handle temperature monitoring, and what sensors are supported?

The ADM1063ACPZ-REEL7 integrates one internal die temperature sensor and two pairs of differential inputs (D1P/D1N and D2P/D2N) for external thermal diodes, enabling simultaneous local and remote temperature measurement. All three sensors are digitized by the same 12-bit ADC, achieving ±3°C accuracy across −40°C to +85°C. Remote measurements use constant-current sources (200 µA high / 12 µA low) to bias external diodes, and the ADM1063ACPZ-REEL7 supports automatic diode identification and offset compensation - critical for accurate board-level thermal profiling.
