Product details
Overview
ADM6711ZAKSZ-REEL from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, featuring a push-pull RESET output, 2.32 V reset threshold (typ), 140 ms minimum reset timeout, and operation down to 1.0 V VCC. It monitors 2.5 V supply rails in portable embedded systems requiring reliable power-on reset and brownout protection.
For engineers reviewing the ADM6711ZAKSZ-REEL datasheet, ADM6711ZAKSZ-REEL pinout, ADM6711ZAKSZ-REEL application, or ADM6711ZAKSZ-REEL equivalent, key selection criteria include reset threshold accuracy over temperature (±0.13 V at −40°C to +85°C), low 12 μA supply current, manual reset debounce (1 μs min pulse width), and SC70 footprint compatibility with space-constrained PCB layouts.
Technical Context
The ADM6711ZAKSZ-REEL integrates a precision voltage reference, comparator, 240 ms typical reset timer, and debounced manual reset input. Its internal architecture asserts RESET low during power-up until VCC exceeds 2.32 V (typ) and remains asserted for ≥140 ms after threshold crossing.
It features glitch immunity against transients as short as 100 ns and sustains valid RESET assertion down to VCC = 1.0 V. The push-pull output eliminates external pull-up components, supporting direct interface with CMOS microprocessors without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.32 V (typ), ±0.13 V over −40°C to +85°C - ensures reliable 2.5 V rail monitoring with margin against supply droop. |
| Supply Current | 12 μA (typ) at VCC < 3.6 V - enables battery-powered operation with minimal quiescent drain. |
| Reset Timeout | 140–460 ms (min–max) - provides sufficient stabilization time for microprocessor clock and memory initialization. |
| VCC Operating Range | 1.0 V to 5.5 V - supports operation during deep brownout and enables use with wide-input DC/DC converters. |
| Manual Reset Pulse Width | ≥1 μs - rejects noise while allowing compact push-button or FPGA-driven reset signaling. |
| Output Type | Push-pull active-low RESET - drives CMOS inputs directly without external components or pull-up resistors. |
| Temperature Range | −40°C to +125°C - qualified for automotive under-hood and industrial control environments. |
Pinout & Package
ADM6711ZAKSZ-REEL is housed in a 4-lead SC70 (KS-4) package measuring 2.20 mm × 1.35 mm × 0.95 mm, optimized for high-density portable designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | 0 V return path for all internal circuits; must be connected to system ground plane for stable threshold reference. |
| RESET | Active-low reset output | Push-pull driver asserting low during power-up/brownout; sinks 1.2 mA at 0.3 V max for robust logic-level compatibility. |
| MR | Debounced manual reset input | Active-low; ignores transients <100 ns; requires ≥1 μs pulse to initiate reset; floats high when unused. |
| VCC | Monitored supply input | Primary power rail being supervised; also powers internal circuitry; operates down to 1.0 V while maintaining reset assertion. |
Key Features
| Feature | Design Value |
|---|---|
| Precision reset threshold | 2.32 V (typ) with 30 ppm/°C tempco - maintains tight tolerance across automotive temperature range. |
| Low-power supervision | 12 μA supply current - extends battery life in always-on IoT sensors and wearables. |
| Glitch-immune MR input | 100 ns noise rejection - prevents spurious resets in electrically noisy motor-control or automotive ECU environments. |
| Wide VCC operating range | 1.0 V to 5.5 V - enables use with Li-ion, coin-cell, and multi-rail power architectures without auxiliary biasing. |
| SC70 footprint | 2.2 mm × 1.35 mm body - saves >60% board area vs. SOT-23, critical for ultra-compact modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326UT23D3+T | 2.33 V threshold, 1.8 μA max ICC, open-drain output, SOT-23-3 package | Lacks manual reset input and push-pull drive; requires external pull-up and separate MR circuitry | Select when ultra-low current (<2 μA) dominates over board area and MR integration. |
| TPS3808G125DBVR | 1.25 V threshold, 16 μA ICC, push-pull output, SOT-23-5 package with watchdog timer | Lower threshold unsuitable for 2.5 V rail; adds watchdog functionality not present in ADM6711ZAKSZ-REEL | Select only if system requires integrated watchdog; otherwise mismatched threshold invalidates direct comparison. |
Compared with MAX6326UT23D3+T and TPS3808G125DBVR, the ADM6711ZAKSZ-REEL uniquely combines 2.32 V threshold, push-pull output, manual reset, and SC70 size-enabling single-chip 2.5 V supervision in area-constrained designs without layout or BOM overhead.

FAQ
What is the exact reset threshold voltage of ADM6711ZAKSZ-REEL and how does it vary with temperature?
The ADM6711ZAKSZ-REEL has a nominal reset threshold of 2.32 V at 25°C, with guaranteed range of 2.25 V to 2.38 V over −40°C to +85°C and 2.22 V to 2.42 V at 85°C to 125°C. Its temperature coefficient is 30 ppm/°C, resulting in ≤±13 mV drift across the full industrial range - sufficient for stable 2.5 V rail supervision without margin violation.
Does ADM6711ZAKSZ-REEL support manual reset, and what are its timing requirements?
Yes, ADM6711ZAKSZ-REEL includes a debounced manual reset (MR) input that accepts active-low pulses ≥1 μs wide and rejects noise spikes <100 ns. When MR is pulled low, RESET remains low for 240 ms (typical) after MR returns high - providing consistent reset duration independent of VCC ramp rate or external timing components.
What is the supply current consumption of ADM6711ZAKSZ-REEL across its operating voltage and temperature range?
ADM6711ZAKSZ-REEL draws 12 μA typical supply current at VCC < 3.6 V and TA = −40°C to +85°C, rising to 60 μA at 85°C to 125°C. At VCC = 1 V, current remains near 12 μA, enabling operation during deep brownout while preserving battery life in always-on applications.
Can ADM6711ZAKSZ-REEL be used to supervise a 2.5 V power rail, and what margin does it provide?
Yes, ADM6711ZAKSZ-REEL is explicitly specified for 2.5 V supply monitoring with a 2.32 V threshold (typ), providing 180 mV design margin below nominal rail. This margin accommodates worst-case 2.5 V rail tolerance (±5%), load regulation error, and transient droop per JEDEC JESD8-12, ensuring no false resets during normal operation.
What package type and dimensions does ADM6711ZAKSZ-REEL use, and is it RoHS compliant?
ADM6711ZAKSZ-REEL uses the 4-lead SC70 (KS-4) package measuring 2.20 mm × 1.35 mm × 0.95 mm, with 0.65 mm lead pitch. The "Z" suffix confirms RoHS compliance per EU Directive 2011/65/EU, including exemption 7a for lead in high-melting-temperature solder alloys used in die attach.
