Analog Devices Inc. ADM1062ACPZ-REEL7

Overview

ADM1062ACPZ-REEL7 from Analog Devices is a configurable supervisory and sequencing IC for multivoltage systems, integrating 10 supply fault detectors (±1% accuracy), a 12-bit ADC for voltage readback, six 8-bit DACs for closed-loop margining (0.300 V–1.551 V), internal/external temperature sensing, and a state-machine-based sequencing engine. It supports complex power-up/down sequencing in DSP/FPGA supply rails.

For engineers reviewing the ADM1062ACPZ-REEL7 datasheet, ADM1062ACPZ-REEL7 pinout, ADM1062ACPZ-REEL7 application, or ADM1062ACPZ-REEL7 equivalent, key selection criteria include its 40-lead 6 mm × 6 mm LFCSP package, SMBus programmability, charge-pumped high-voltage PDO outputs (up to 14 V), dual-mode VXx inputs (analog fault detection or digital logic), and integrated EEPROM for configuration persistence.

Technical Context

The ADM1062ACPZ-REEL7 implements a deterministic state-machine sequencing engine with up to 63 programmable states, enabling conditional output transitions based on input events (e.g., supply OK, fault, timer expiry). Its 12-bit SAR ADC digitizes VH, VPx, and VXx inputs-attenuated per selected range-with round-robin scanning and 16× averaging support.

Margining is implemented via six buffered 8-bit DACs driving dc-to-dc converter feedback or reference nodes; each DAC offers four center-point ranges (0.6 V to 1.25 V) and ±0.75 LSB INL. The device powers itself from the highest active VPx or VH rail (3.0 V–14.4 V), regulating to 4.75 V on VDDCAP with 10 μF decoupling.

FAQ

What is the primary function of the ADM1062ACPZ-REEL7 in a power system?

The ADM1062ACPZ-REEL7 serves as a configurable supervisory and sequencing controller that monitors up to 10 voltage rails, executes programmable power-up/down sequences via its state-machine sequencing engine, and performs closed-loop voltage margining using six integrated 8-bit DACs. It also provides temperature monitoring and SMBus-based system communication. This makes ADM1062ACPZ-REEL7 ideal for complex multirail systems like servers and FPGA boards where reliability and precision are critical.

Does the ADM1062ACPZ-REEL7 support both high-voltage and low-voltage programmable outputs?

Yes, the ADM1062ACPZ-REEL7 supports dual-mode outputs: PDO1–PDO6 can operate in charge-pumped high-voltage mode (up to 14 V) to drive N-FET gates, or in standard low-voltage push-pull/open-collector mode referenced to VDDCAP or VPx. PDO7–PDO10 are low-voltage only. This flexibility allows ADM1062ACPZ-REEL7 to control both power-path FETs and logic-level enable signals within the same design.

How does the ADM1062ACPZ-REEL7 achieve power supply redundancy?

The ADM1062ACPZ-REEL7 achieves redundancy by powering itself from the highest active voltage among VH or VP1–VP4 rails (minimum 3.0 V), using an internal arbitrator that behaves like five LDOs OR'd together. This ensures continued operation even if one supply fails. The VDDCAP output is regulated to ~4.75 V with only ~0.2 V dropout, allowing ADM1062ACPZ-REEL7 to remain functional down to 3.0 V on any single input rail.

Can the ADM1062ACPZ-REEL7 perform in-circuit voltage margining without external components?

Yes, ADM1062ACPZ-REEL7 implements closed-loop margining with minimal external components: its six 8-bit DACs inject precise voltage offsets into dc-to-dc converter feedback or reference nodes, while its 12-bit ADC reads back actual rail voltages to verify margining accuracy. No external DACs, op-amps, or ADCs are required-enabling production test at ±5% nominal supplies directly on the board using ADM1062ACPZ-REEL7.

What package type and pin count does the ADM1062ACPZ-REEL7 use?

The ADM1062ACPZ-REEL7 uses a 40-lead, 6 mm × 6 mm LFCSP package with an exposed pad (NC, recommended for mechanical stability). This compact, thermally efficient package is validated for high-density server and telecom PCB layouts and matches the pinout shown in Analog Devices' Rev. D datasheet Figure 3 and Table 4.
