Product details
Overview
ADM6711ZAKS-REEL from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, providing precision reset generation for 2.5 V systems with 2.32 V threshold (25°C), 140 ms minimum reset timeout, push-pull active-low RESET output, and manual reset input with 1 μs minimum pulse width. It ensures reliable power-up sequencing in portable microcontroller-based instrumentation.
For engineers reviewing the ADM6711ZAKS-REEL datasheet, ADM6711ZAKS-REEL pinout, ADM6711ZAKS-REEL application, or ADM6711ZAKS-REEL equivalent, key selection criteria include supply voltage monitoring accuracy down to 1 V VCC, low 12 μA quiescent current at 3.6 V, glitch immunity against 100 ns transients, and −40°C to +125°C operating range suitability for automotive and industrial edge nodes.
Technical Context
The ADM6711ZAKS-REEL integrates a precision bandgap reference, comparator with hysteresis, debounced manual reset logic, and push-pull output driver. Its reset assertion remains active until VCC exceeds 2.32 V (typ) and sustains for ≥140 ms after crossing threshold, ensuring stable power rail establishment before processor release.
It features internal filtering for power supply glitch immunity up to 100 ns, operates with supply voltages from 1.0 V to 5.5 V across full temperature range, and maintains reset functionality down to 1 V VCC - enabling robust brownout detection in battery-powered systems where supply collapse may be gradual.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326UT23+T | 2.32 V threshold, open-drain output, 1.2 μA max ICC, SOT23-3 package | Lacks manual reset input; requires external pull-up; lower current draw but no MR flexibility | Select when board space is critical and manual reset is unnecessary; verify pull-up voltage compatibility |
| TPS3808G125DBVR | 2.35 V threshold, push-pull output, 16 μA ICC, SOT23-6 package | Includes watchdog timer and programmable delay; larger footprint and higher quiescent current | Choose when system-level watchdog supervision is required alongside reset; accept 4× current penalty for added feature set |
Compared with MAX6326UT23+T and TPS3808G125DBVR, ADM6711ZAKS-REEL delivers manual reset capability in the smallest footprint (SC70) with lowest current (12 μA) and guaranteed 1 V VCC operation - making it optimal for cost- and size-sensitive 2.5 V microcontroller systems lacking watchdog needs.

FAQ
What is the reset threshold voltage of ADM6711ZAKS-REEL and how does it vary with temperature?
The ADM6711ZAKS-REEL has a nominal reset threshold of 2.32 V at 25°C, with a specified range of 2.25 V to 2.38 V over −40°C to +85°C and 2.22 V to 2.42 V over 85°C to +125°C. Its temperature coefficient is 30 ppm/°C, ensuring predictable trip-point drift across automotive and industrial operating conditions. This makes ADM6711ZAKS-REEL suitable for monitoring 2.5 V rails where tight voltage margin control is essential.
Does ADM6711ZAKS-REEL support operation below 2.5 V supply voltage?
Yes, ADM6711ZAKS-REEL operates from 1.0 V to 5.5 V and asserts RESET down to 1 V VCC, enabling use in deep brownout scenarios such as lithium battery discharge or unregulated input stages. Its internal reference remains functional and accurate even as VCC declines, allowing ADM6711ZAKS-REEL to provide deterministic reset behavior far beyond typical 2.5 V system boundaries.
What is the function of the MR pin on ADM6711ZAKS-REEL and what are its timing requirements?
The MR (Manual Reset) pin on ADM6711ZAKS-REEL is an active-low, debounced input that initiates a reset cycle independent of VCC level. It accepts pulses ≥1 μs wide and rejects glitches <100 ns. When pulled low, ADM6711ZAKS-REEL holds RESET low for 240 ms (typical) after MR returns high. This allows direct connection to pushbuttons or logic signals without external filtering - a key design advantage of ADM6711ZAKS-REEL.
How does the push-pull RESET output of ADM6711ZAKS-REEL differ from open-drain alternatives?
The ADM6711ZAKS-REEL features a push-pull RESET output that actively drives both high (≥0.8×VCC) and low (≤0.3 V at 1.2 mA sink), eliminating the need for an external pull-up resistor. This simplifies layout, reduces component count, and avoids voltage translation issues common with open-drain outputs like those in ADM6713 variants. The push-pull architecture ensures fast, rail-to-rail signaling compatible with most microcontroller reset inputs - a defining characteristic of ADM6711ZAKS-REEL.
Is ADM6711ZAKS-REEL RoHS compliant and what is its packaging format?
Yes, ADM6711ZAKS-REEL is RoHS compliant (denoted by "Z" in the part number suffix) and supplied in tape-and-reel format (REEL) with 10,000 units per reel. It uses a Pb-free, halogen-free 4-lead SC70 (KS-4) package measuring 2.20 mm × 1.35 mm, meeting JEDEC standards for reflow soldering and automated assembly. This packaging supports high-density placement in portable and automotive electronics where ADM6711ZAKS-REEL is commonly deployed.
