Product details
Overview
ADM6711TAKSZ-REEL7 from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, providing precision reset assertion for 3.08 V supply monitoring with 140 ms minimum timeout, push-pull RESET output, and operation down to 1.0 V VCC. It delivers low-power supervision (12 μA typical) for embedded microcontroller power-up sequencing in portable instrumentation.
For engineers reviewing the ADM6711TAKSZ-REEL7 datasheet, ADM6711TAKSZ-REEL7 pinout, ADM6711TAKSZ-REEL7 application, or ADM6711TAKSZ-REEL7 equivalent, key selection criteria include reset threshold accuracy (3.08 V ±3%, −40°C to +125°C), glitch immunity (100 ns), manual reset debounce, and push-pull output eliminating external pull-up components.
Technical Context
The ADM6711TAKSZ-REEL7 integrates a precision voltage reference, comparator, and 240 ms typical reset timeout timer. Its internal debounced MR input rejects transients <100 ns while guaranteeing response to ≥1 μs pulses, enabling reliable manual reset in noisy environments.
Reset assertion occurs when VCC falls below 3.08 V (typical), with threshold drift limited to 30 ppm/°C. The push-pull output drives high to 0.8×VCC at 500 μA source current and low to 0.3 V at 1.2 mA sink current, supporting direct interface to CMOS inputs without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.08 V (typical), ±3% over −40°C to +125°C - ensures accurate 3.3 V rail supervision during brownout |
| Reset Timeout | 140–460 ms active period - provides sufficient stabilization time for microprocessor core and peripherals |
| Supply Current | 12 μA (typical at VCC < 3.6 V, −40°C to +85°C) - enables multi-year battery life in portable systems |
| 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 minimum pulse rejection - prevents false resets from EMI or switch bounce |
| Output Type | Push-pull active-low RESET - eliminates need for external pull-up resistor and simplifies PCB layout |
| Package | 4-lead SC70 (KS-4), 2.2 mm × 1.35 mm - ultra-compact footprint for space-constrained embedded designs |
Pinout & Package
ADM6711TAKSZ-REEL7 uses a 4-lead SC70 (KS-4) package with exposed pad not electrically connected. Pin 1 is GND, Pin 2 is active-low RESET output, Pin 3 is active-low manual reset (MR) input, and Pin 4 is monitored supply (VCC).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (GND) | Ground reference | Common 0 V return for all internal circuits and external connections |
| 2 (RESET) | Active-low reset output | Push-pull driver asserts low during power-up, brownout, or MR activation; releases high after timeout |
| 3 (MR) | Active-low manual reset input | Debounced input accepts ≥1 μs pulses; ignores noise spikes <100 ns; floats high when unused |
| 4 (VCC) | Monitored supply input | Primary power rail under supervision; also powers internal circuitry; valid down to 1.0 V |
Key Features
| Feature | Design Value |
|---|---|
| Precision 3.08 V threshold | ±3% tolerance over full −40°C to +125°C range ensures robust 3.3 V system reset across automotive and industrial environments |
| 140 ms minimum reset timeout | Guarantees microprocessor reset hold time exceeds worst-case power supply stabilization delay |
| 12 μA typical supply current | Enables integration into always-on subsystems without compromising battery runtime |
| 1 V VCC reset assertion | Maintains valid reset signal during deep undervoltage events, preventing processor runaway |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326UT31D+T | 3.08 V threshold, open-drain output, 1.6 μA supply current, SOT-23-3 package | Lacks manual reset input and operates only down to 2.0 V VCC - unsuitable for sub-2 V brownout detection | Select when ultra-low quiescent current is critical and MR functionality is unnecessary |
| TPS3808G33DBVR | 3.3 V threshold (not 3.08 V), push-pull output, 16 μA supply current, SOT-23-6 package | Higher threshold reduces noise margin on 3.3 V rails; requires PCB redesign due to 6-pin footprint and different pinout | Select only if 3.3 V nominal threshold suffices and board layout allows SOT-23-6 placement |
Compared with MAX6326UT31D+T and TPS3808G33DBVR, ADM6711TAKSZ-REEL7 uniquely combines 3.08 V precision threshold, 1 V VCC operation, integrated MR debounce, and SC70 footprint - making it optimal for space-constrained, wide-temperature industrial and automotive reset applications requiring deterministic brownout response.

FAQ
What is the exact reset threshold voltage of ADM6711TAKSZ-REEL7 and how does it vary with temperature?
The ADM6711TAKSZ-REEL7 has a nominal reset threshold of 3.08 V at 25°C, with guaranteed range of 3.00 V to 3.15 V over −40°C to +85°C and 2.95 V to 3.21 V over 85°C to +125°C. Its temperature coefficient is 30 ppm/°C, resulting in ≤0.5% total drift across the full industrial temperature range - sufficient for stable 3.3 V rail supervision without calibration.
Does ADM6711TAKSZ-REEL7 support manual reset, and what are its timing requirements?
Yes, ADM6711TAKSZ-REEL7 includes a debounced manual reset (MR) input on Pin 3. It rejects transients shorter than 100 ns (typical) and guarantees recognition of any active-low pulse ≥1 μs in duration. When asserted, MR holds RESET low and maintains it for 240 ms (typical) after release - ensuring consistent system-wide reset propagation regardless of MCU clock speed.
What is the minimum VCC voltage at which ADM6711TAKSZ-REEL7 continues to assert a valid RESET signal?
ADM6711TAKSZ-REEL7 asserts RESET down to 1.0 V VCC, as specified in the Absolute Maximum Ratings and confirmed in functional operation tables. Below 0.8 V, the output enters high-impedance state; therefore, for guaranteed logic-low assertion across full undervoltage, the device remains fully functional from 1.0 V to 5.5 V - critical for battery-fail-safe designs.
How does the push-pull RESET output of ADM6711TAKSZ-REEL7 differ from open-drain alternatives?
The push-pull RESET output of ADM6711TAKSZ-REEL7 actively drives both high (to 0.8×VCC at 500 μA) and low (to 0.3 V at 1.2 mA), eliminating the need for an external pull-up resistor. This reduces BOM count, avoids logic-level ambiguity during VCC ramp-up, and enables direct connection to standard CMOS inputs - unlike open-drain variants such as ADM6713TAKSZ-REEL7 that require external biasing.
Is ADM6711TAKSZ-REEL7 RoHS compliant and what packaging format does it use?
Yes, ADM6711TAKSZ-REEL7 is RoHS compliant, indicated by the "Z" suffix in the part number per Analog Devices' Ordering Guide. It is supplied in tape-and-reel format (REEL7 denotes 3 k unit reel) and housed in a 4-lead SC70 (KS-4) package measuring 2.2 mm × 1.35 mm - optimized for automated pick-and-place assembly in high-density PCB layouts.
