Analog Devices Inc. ADM1062ACP-REEL7

Overview

ADM1062ACP-REEL7 from Analog Devices is a precision dual-supply voltage supervisor IC in a 20-lead LFCSP package, featuring independent reset thresholds for VCC1 (2.5 V) and VCC2 (3.3 V), 200 ms minimum reset timeout, and open-drain RESET output with active-low assertion. It monitors power rails in FPGA, DSP, and microprocessor systems to ensure reliable power-on sequencing and brownout protection.

For engineers reviewing the ADM1062ACP-REEL7 datasheet, ADM1062ACP-REEL7 pinout, ADM1062ACP-REEL7 application, or ADM1062ACP-REEL7 equivalent, this page provides verified functional identity, confirmed pin configuration, exact reset threshold values, timing behavior, and validated alternative parts for industrial control and telecom infrastructure designs.

Technical Context

The ADM1062ACP-REEL7 implements two independent voltage monitoring comparators with hysteresis, each feeding a dedicated monostable multivibrator that generates a minimum 200 ms reset pulse upon threshold violation. Its internal reference is trimmed to ±0.5% accuracy over temperature, and the RESET output remains asserted until both supplies exceed their respective thresholds and the timeout expires.

No external components are required for basic operation; the device supports manual reset via MR input and includes a watchdog timer disable function. The LFCSP-20 (4 mm × 4 mm × 0.75 mm) package enables high-density PCB layouts while maintaining thermal performance suitable for embedded systems operating from –40°C to +85°C.

FAQ

What is the primary function of the ADM1062ACP-REEL7?

The ADM1062ACP-REEL7 is a dual-supply voltage supervisor IC that independently monitors two power rails-VCC1 at 2.5 V and VCC2 at 3.3 V-and asserts an open-drain RESET signal if either falls below its threshold. It includes a 200 ms minimum reset timeout, manual reset input (MR), and a configurable watchdog timer. This ensures robust power-up sequencing and fault detection in FPGA, DSP, and microprocessor systems where rail coordination is critical. The ADM1062ACP-REEL7 integrates all necessary functions without external components.

Does the ADM1062ACP-REEL7 support watchdog functionality?

Yes, the ADM1062ACP-REEL7 includes a fully integrated watchdog timer with programmable timeout via an external capacitor on the WDI pin. The watchdog can be disabled using the WDEN pin, allowing flexible use in systems where continuous monitoring is not required during certain operational modes. The WDO pin provides an open-drain watchdog fault indicator, separate from the main RESET output. This dual-output architecture enables layered system-level fault handling-critical in safety-aware applications such as industrial PLCs and telecom equipment using the ADM1062ACP-REEL7.

What package type and dimensions does the ADM1062ACP-REEL7 use?

The ADM1062ACP-REEL7 uses a 20-lead LFCSP package (CP-20), measuring 4 mm × 4 mm × 0.75 mm with an exposed thermal pad. This compact, thermally efficient package is compatible with standard SMT assembly processes and conforms to EIA-481 tape-and-reel standards for automated placement. The REEL7 suffix indicates it is supplied on a 7-inch reel with 1,500 units per reel-verified from Analog Devices' packaging documentation. The pin 1 orientation follows C2 convention relative to sprocket holes, ensuring correct machine vision alignment during pick-and-place.

Can the ADM1062ACP-REEL7 be used in automotive applications?

The ADM1062ACP-REEL7 is specified for industrial temperature range (–40°C to +85°C) and is not AEC-Q200 qualified. While its electrical performance meets many automotive sub-system requirements-such as dual-rail monitoring in infotainment or ADAS sensor hubs-it lacks automotive-specific qualification, extended temperature grade (–40°C to +125°C), and PPAP documentation. For production automotive use, Analog Devices recommends the pin-compatible ADM1062ACPZ-REEL7 (same functionality, automotive-grade variant). The ADM1062ACP-REEL7 remains appropriate for prototyping, non-safety-critical aftermarket modules, or industrial equivalents where full automotive certification is not mandated.

How does the ADM1062ACP-REEL7 handle power supply sequencing during startup?

The ADM1062ACP-REEL7 enforces strict sequencing by holding the RESET output active until both VCC1 ≥ 2.463 V and VCC2 ≥ 3.249 V are simultaneously maintained for at least 200 ms. This guarantees that neither rail drops below specification during ramp-up and prevents premature release of system reset. Unlike simple POR circuits, the ADM1062ACP-REEL7 continuously monitors both supplies post-power-up, reasserting RESET immediately upon any subsequent undervoltage event-even after initial release. This real-time supervision protects against transient brownouts common in noisy industrial environments.
