Product details
Overview
ADM6711LAKSZ-REEL from Analog Devices is a precision microprocessor supervisory circuit in 4-lead SC70 package, featuring a 4.63 V reset threshold, push-pull active-low RESET output, 140 ms minimum reset timeout, and operation down to 1.0 V VCC. It monitors 5 V power rails in automotive and industrial microprocessor systems requiring reliable power-on reset and brownout protection.
For engineers reviewing the ADM6711LAKSZ-REEL datasheet, ADM6711LAKSZ-REEL pinout, ADM6711LAKSZ-REEL application, or ADM6711LAKSZ-REEL equivalent, key selection criteria include reset threshold accuracy over −40°C to +125°C, low 12 μA supply current, manual reset debouncing, glitch immunity up to 100 ns, and compatibility with 5 V supply monitoring in space-constrained embedded designs.
Technical Context
The ADM6711LAKSZ-REEL integrates a precision voltage reference, comparator with 30 ppm/°C temperature coefficient, and a 240 ms typical internal timer for reset assertion after VCC rise. Its push-pull RESET output drives logic directly without external components, supporting fast, deterministic release timing.
It features a debounced manual reset (MR) input with guaranteed 1 μs minimum pulse acceptance and 100 ns glitch rejection. The device asserts RESET down to 1.0 V VCC and maintains valid logic levels across its full −40°C to +125°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.63 V (nominal at 25°C), ±60 mV over −40°C to +85°C - precisely targets 5 V supply monitoring with margin for ripple and drift. |
| Reset Timeout | 140–460 ms (min/typ/max) - ensures stable power-up before microprocessor execution begins. |
| Supply Current | 12 μA (typ) at VCC < 3.6 V, −40°C to +85°C - enables battery-backed or ultra-low-power portable applications. |
| VCC Operating Range | 1.0 V to 5.5 V - supports valid reset assertion even during deep brownout or partial power loss. |
| MR Input Glitch Immunity | 100 ns - rejects noise spikes on manual reset line without external filtering in most layouts. |
| RESET Output Type | Push-pull active-low - eliminates need for external pull-up resistor and simplifies interface to CMOS/TTL inputs. |
| Temperature Range | −40°C to +125°C - qualified for under-hood automotive and industrial control environments. |
Pinout & Package
ADM6711LAKSZ-REEL is housed in a 4-lead SC70 (KS-4) package measuring 2.20 mm × 1.35 mm × 0.9 mm, optimized for high-density PCB layouts and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - GND | Ground reference | 0 V return path for all internal circuitry; must be connected to system ground plane for stable threshold reference. |
| 2 - RESET | Active-low reset output | Push-pull driver asserts low during power-up, brownout, or MR activation; releases high after timeout completes. |
| 3 - MR | Debounced manual reset input | Active-low; accepts ≥1 μs pulses, ignores <100 ns transients; floats high when unused. |
| 4 - VCC | Monitored supply input | Connects directly to 5 V rail being supervised; powers internal circuitry and defines reset threshold reference. |
Key Features
| Feature | Design Value |
|---|---|
| Precision 4.63 V threshold | Guaranteed ±60 mV tolerance over −40°C to +85°C - eliminates need for external trimming in 5 V systems. |
| 12 μA typical quiescent current | Enables >10-year battery life in always-on supervisory applications with coin-cell backup. |
| 140 ms minimum reset timeout | Provides sufficient hold time for 5 V LDO stabilization and microcontroller oscillator startup. |
| Reset assertion down to 1.0 V VCC | Ensures fail-safe behavior during severe undervoltage events where other supervisors may release prematurely. |
| 100 ns MR input glitch immunity | Reduces need for RC filtering on reset buttons or noisy control lines in industrial enclosures. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326US46D3+T | 4.63 V threshold, SOT-23-3, open-drain output, 1.6 μA max ICC | Requires external pull-up; lower current but no MR input | Select when board area is critical and manual reset is unnecessary. |
| TPS3808G33DBVR | 3.3 V threshold, SOT-23-6, push-pull output, 16 μA ICC, adjustable delay | Fixed 3.3 V threshold; incompatible for 5 V monitoring without external divider | Choose only if redesigning for 3.3 V core supply and needing programmable timeout. |
Compared with MAX6326US46D3+T and TPS3808G33DBVR, the ADM6711LAKSZ-REEL uniquely combines 4.63 V precision threshold, push-pull output, manual reset input, and −40°C to +125°C operation in a 4-pin SC70 - making it the only drop-in solution for legacy 5 V automotive and industrial designs requiring all three functions without layout change.

FAQ
What is the reset threshold voltage of the ADM6711LAKSZ-REEL?
The ADM6711LAKSZ-REEL has a nominal reset threshold of 4.63 V at 25°C, with guaranteed tolerance of 4.50 V to 4.75 V over −40°C to +85°C and 4.44 V to 4.82 V over 85°C to 125°C. This makes it specifically suited for monitoring standard 5 V power supplies while accommodating manufacturing variation and thermal drift.
Does the ADM6711LAKSZ-REEL require an external pull-up resistor on the RESET pin?
No, the ADM6711LAKSZ-REEL features a push-pull RESET output, so it actively drives both high and low states without requiring an external pull-up resistor. This simplifies design, reduces BOM count, and ensures predictable rise/fall times - unlike the open-drain ADM6713 variant which does require an external pull-up.
What is the minimum pulse width accepted on the MR pin of the ADM6711LAKSZ-REEL?
The MR input of the ADM6711LAKSZ-REEL guarantees acceptance of active-low pulses ≥1 μs in duration and rejects transients <100 ns. This built-in debouncing eliminates the need for external RC filters in most applications, though a 0.1 μF capacitor to ground is recommended for long MR traces in noisy environments.
Can the ADM6711LAKSZ-REEL operate reliably at 1.2 V VCC?
Yes - the ADM6711LAKSZ-REEL is specified to assert RESET down to 1.0 V VCC and operates across a full VCC range of 1.0 V to 5.5 V. At 1.2 V, it maintains valid reset assertion and retains functional integrity, enabling fail-safe behavior during deep brownout conditions where many competing supervisors cease operation.
Is the ADM6711LAKSZ-REEL RoHS compliant?
Yes, the "Z" suffix in ADM6711LAKSZ-REEL explicitly denotes RoHS compliance per Analog Devices' ordering guide. It contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and meets JEDEC J-STD-609A Class 3 marking requirements.
