Product details
Overview
ADM6711RAKSZ-REEL7 from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, designed to monitor 2.63 V supply rails with ±0.05 V threshold accuracy over −40°C to +125°C, assert active-low RESET for ≥140 ms on power-up/brownout, and support manual reset via debounced MR input. It serves as a system-level power integrity guard in portable microcontroller applications.
For engineers reviewing the ADM6711RAKSZ-REEL7 datasheet, ADM6711RAKSZ-REEL7 pinout, ADM6711RAKSZ-REEL7 application, or ADM6711RAKSZ-REEL7 equivalent, key selection criteria include its push-pull RESET output (no external pull-up required), 12 μA typical supply current at 3.6 V, reset assertion down to 1 V VCC, 100 ns glitch immunity, and compatibility with 2.5 V/3 V/3.3 V systems requiring high-temperature reliability.
Technical Context
The ADM6711RAKSZ-REEL7 integrates a precision voltage reference, comparator with 30 ppm/°C temperature coefficient, and a 240 ms typical reset timeout generator. Its internal debounce logic rejects MR pulses <100 ns while guaranteeing response to ≥1 μs low-going transitions.
It features power supply glitch immunity up to 1000 mV overdrive with transient rejection durations mapped across temperature, and ensures valid RESET output down to VCC = 1 V via internal current-sinking capability-enabling robust operation during deep brownouts without external components.
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 |
|---|---|---|---|
| ADM6711RAKS-REEL7 | Same 2.63 V threshold and SC70 package; differs only in tape-and-reel quantity (3 k vs. 10 k) and branding (M5F vs. M0F) | No functional difference; identical electrical and thermal performance | Select ADM6711RAKSZ-REEL7 when RoHS-compliant (Z-suffix) marking and smaller reel size are required. |
| MAX6326UR26-T | 2.63 V threshold, SOT-23-3 package, open-drain output, 1.6 μA supply current, but lacks MR input and has 200 ms min timeout | Not suitable where manual reset or push-pull drive is mandatory; lower current but reduced feature set | Choose MAX6326UR26-T only if ultra-low current dominates design priority and MR functionality is omitted. |
Compared with ADM6711RAKSZ-REEL7, ADM6711RAKS-REEL7 offers identical supervision performance with non-RoHS packaging, while MAX6326UR26-T trades MR input and push-pull drive for lower quiescent current-making it viable only in simplified, non-manual-reset applications where SOT-23-3 footprint is preferred.

FAQ
What is the reset threshold voltage of the ADM6711RAKSZ-REEL7?
The ADM6711RAKSZ-REEL7 has a nominal reset threshold of 2.63 V at 25°C, with guaranteed range of 2.55 V to 2.70 V over −40°C to +85°C and 2.52 V to 2.74 V over 85°C to 125°C. This makes it suitable for precise monitoring of 2.5 V power rails in demanding environments where voltage margin and temperature stability are critical.
Does the ADM6711RAKSZ-REEL7 require an external pull-up resistor on the RESET pin?
No, the ADM6711RAKSZ-REEL7 features a push-pull RESET output, so no external pull-up resistor is needed. This simplifies PCB layout and reduces component count compared to open-drain alternatives like the ADM6713 series. The output actively drives high to ≥0.8 × VCC and low to ≤0.3 V under specified load conditions.
What is the minimum pulse width accepted on the MR input of the ADM6711RAKSZ-REEL7?
The MR input of the ADM6711RAKSZ-REEL7 requires a minimum low-going pulse width of 1 μs to guarantee recognition. It also provides built-in debounce, rejecting transients shorter than 100 ns. This allows direct connection to mechanical switches or digital logic without additional RC filtering in most cases.
Can the ADM6711RAKSZ-REEL7 operate when VCC drops below 2.5 V?
Yes, the ADM6711RAKSZ-REEL7 operates down to VCC = 1.0 V and continues asserting RESET until VCC rises above the 2.63 V threshold. Its ability to assert reset down to 1 V VCC ensures reliable brownout detection even during deep supply sags, making it suitable for battery-backed or energy-harvesting systems.
Is the ADM6711RAKSZ-REEL7 RoHS compliant?
Yes, the "Z" suffix in ADM6711RAKSZ-REEL7 explicitly denotes RoHS compliance per Analog Devices' ordering guide. It meets EU Directive 2011/65/EU requirements and contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE).
