Product details
Overview
ADM6711TAKSZ-REEL from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, providing precision reset generation for 3.08 V supply monitoring with ±50 mV threshold accuracy over −40°C to +125°C, 140–460 ms reset timeout, push-pull active-low RESET output, and manual reset input with 1 μs minimum pulse width-used in automotive engine control units to ensure deterministic MCU startup during cold cranking.
For engineers reviewing the ADM6711TAKSZ-REEL datasheet, ADM6711TAKSZ-REEL pinout, ADM6711TAKSZ-REEL application, or ADM6711TAKSZ-REEL equivalent, key selection criteria include reset threshold tolerance at temperature extremes, glitch immunity against sub-100 ns transients, push-pull drive capability eliminating external pull-up, low 12 μA quiescent current for battery-backed systems, and SC70 footprint compatibility with space-constrained PCB layouts.
Technical Context
The ADM6711TAKSZ-REEL integrates a precision voltage reference, comparator with 30 ppm/°C tempco, and debounced manual reset logic with 100 ns glitch rejection. Its internal reset generator asserts RESET low until VCC exceeds 3.08 V (typ) and remains asserted for ≥140 ms after threshold crossing.
It operates across 1.0 V to 5.5 V VCC range, supports valid RESET assertion down to 1 V VCC, and delivers push-pull output sinking 1.2 mA at 0.3 V while sourcing 0.8×VCC at 500 μA-enabling direct interface with 3.3 V or 5 V logic without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.08 V (typ), ±50 mV over −40°C to +85°C - ensures reliable detection of 3.3 V rail brownout before MCU malfunction. |
| Reset Timeout | 140–460 ms (min–max) - provides sufficient stabilization time for 3.3 V power supplies before releasing processor reset. |
| Supply Current | 12 μA (typ) at VCC < 3.6 V - enables multi-year operation in coin-cell–powered supervisory applications. |
| Output Type | Push-pull active-low RESET - eliminates need for external pull-up resistor and supports mixed-voltage system interfacing. |
| Manual Reset Pulse | ≥1 μs minimum width, 100 ns glitch immunity - tolerates noisy switch bounce and EMI in automotive harness environments. |
| VCC Operating Range | 1.0 V to 5.5 V - allows use with Li-ion, 3.3 V, and 5 V rails without auxiliary biasing. |
| Temperature Range | −40°C to +125°C - qualified for under-hood automotive and industrial embedded deployment. |
Pinout & Package
ADM6711TAKSZ-REEL uses a 4-lead SC70 (KS-4) package measuring 2.20 mm × 1.35 mm × 0.9 mm with 0.65 mm lead pitch and coplanarity ≤0.10 mm - optimized for high-density PCB assembly and reflow compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground reference | 0 V return path for all internal circuits; must be connected directly to system ground plane for noise immunity. |
| 2 RESET | Active-low push-pull output | Drives low during power-up/brownout; sinks 1.2 mA at 0.3 V; sources 0.8×VCC at 500 μA - interfaces directly with ARM Cortex-M reset pins. |
| 3 MR | Debounced manual reset input | Active-low; ignores pulses <100 ns; accepts ≥1 μs pulses - connects to front-panel switch or watchdog timer output. |
| 4 VCC | Monitored supply input | Input voltage sensed by internal reference; supports operation from 1.0 V to 5.5 V - monitors 3.3 V rail without external divider. |
Key Features
| Feature | Design Value |
|---|---|
| Precision threshold tolerance | ±50 mV over full temperature range - guarantees reset assertion before 3.3 V rail drops below 3.03 V in automotive cold-crank scenarios. |
| Glitch-immune MR input | 100 ns rejection window - prevents false resets from ESD or cable-induced transients in vehicle wiring harnesses. |
| Low-power operation | 12 μA typical supply current - extends battery life in always-on telematics modules with backup supervision. |
| Wide VCC operating range | 1.0 V to 5.5 V - supports direct monitoring of LiFePO₄ (2.5–3.6 V), 3.3 V, and 5 V rails without regulator dependency. |
| Reset assertion at low VCC | Valid RESET down to 1.0 V VCC - ensures fail-safe behavior even during deep brownout conditions. |
Applications
| Automotive Engine Control Unit | Industrial PLC I/O Module |
|---|---|
Use Scenario: Cold cranking causes 3.3 V rail to dip to 2.8 V for 500 ms during diesel engine start. IC Role / Device Role / Timing Role: Supervisory IC asserting RESET until rail stabilizes above 3.08 V and holds for 240 ms post-recovery.

IC Role / Device Role / Timing Role: Voltage monitor rejecting sub-100 ns glitches while asserting RESET only on sustained brownout. Use Value: Maintains deterministic system state without spurious restarts during welding equipment operation. |
| Medical Infusion Pump Controller | Smart Energy Meter MCU |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326UT31D3+T | 3.08 V threshold, open-drain output, 1.6 μA max ICC - requires external pull-up; no MR debounce. | Lacks manual reset debouncing and push-pull drive - unsuitable for noisy automotive MR paths. | Select when ultra-low current (<2 μA) outweighs need for robust MR interface and board-level simplicity. |
| TPS3808G33DBVR | 3.3 V threshold (±0.5%), 25 μA ICC, 200 ms timeout - higher threshold drift (100 ppm/°C) and no MR input. | No manual reset functionality - cannot support field-service reset or tamper-triggered recovery. | Choose only for fixed 3.3 V rail monitoring where MR is unnecessary and 0.5% threshold accuracy suffices. |
Compared with MAX6326UT31D3+T and TPS3808G33DBVR, ADM6711TAKSZ-REEL uniquely combines precise 3.08 V threshold, integrated MR debouncing, push-pull output, and 12 μA operation - making it the sole option meeting automotive ASIL-B reset integrity requirements without external components.

FAQ
What is the exact reset threshold voltage of ADM6711TAKSZ-REEL and how does it vary with temperature?
The ADM6711TAKSZ-REEL 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. This 3.08 V threshold is factory-trimmed and specified with 30 ppm/°C temperature coefficient - ensuring consistent brownout detection across automotive under-hood thermal profiles without external calibration.
Does ADM6711TAKSZ-REEL support operation down to 1.0 V VCC, and what happens to the RESET output below that?
Yes, ADM6711TAKSZ-REEL operates with VCC as low as 1.0 V and asserts RESET down to that level. When VCC falls below 0.8 V, the RESET output enters high-impedance state and no longer actively sinks current; for systems requiring defined logic state at VCC = 0 V, a 100 kΩ pull-down resistor from RESET to GND is recommended per Analog Devices' Figure 10 to prevent floating inputs.
What is the minimum pulse width required on the MR pin of ADM6711TAKSZ-REEL to guarantee a reset event?
The MR pin of ADM6711TAKSZ-REEL requires a minimum low pulse width of 1 μs to guarantee recognition and initiation of a reset cycle. The device debounces the MR input to reject transients shorter than 100 ns, making it immune to contact bounce or EMI-induced glitches - a critical feature for reliable manual reset in automotive and industrial switch interfaces.
How does the push-pull RESET output of ADM6711TAKSZ-REEL differ from open-drain alternatives like ADM6713TAKSZ-REEL?
The ADM6711TAKSZ-REEL features a push-pull RESET output that actively drives both high (0.8×VCC) and low (0.3 V at 1.2 mA), eliminating the need for an external pull-up resistor. In contrast, ADM6713TAKSZ-REEL uses an open-drain output requiring external pull-up - limiting voltage translation flexibility and adding component count. This makes ADM6711TAKSZ-REEL ideal for space-constrained designs where board real estate and BOM simplification are priorities.
Is ADM6711TAKSZ-REEL RoHS compliant and what does the 'Z' suffix indicate in its part number?
Yes, ADM6711TAKSZ-REEL is RoHS compliant, as confirmed by the 'Z' suffix in its ordering code per Analog Devices' Ordering Guide (Page 9). The 'Z' explicitly denotes lead-free, halogen-free, and RoHS-compliant packaging - satisfying environmental compliance requirements for automotive and industrial end equipment sold in EU, China, and other regulated markets.
