Product details
Overview
ADM6711LAKS-REEL from Analog Devices is a precision microprocessor supervisory circuit in 4-lead SC70 packaging, 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-up/power-down reset assertion.
For engineers reviewing the ADM6711LAKS-REEL datasheet, ADM6711LAKS-REEL pinout, ADM6711LAKS-REEL application, or ADM6711LAKS-REEL equivalent, key selection criteria include reset threshold accuracy over −40°C to +125°C, low 12 μA supply current, manual reset debounce timing, glitch immunity against 100 ns transients, and compatibility with 5 V supply stabilization sequences.
Technical Context
The ADM6711LAKS-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 above threshold. Its push-pull output eliminates external pull-up components and supports direct interface to CMOS inputs.
It features a debounced manual reset (MR) input with guaranteed 1 μs minimum pulse acceptance and 100 ns glitch rejection, plus power supply glitch immunity validated up to 1000 mV overdrive with transient durations under 10 μs at VTH − VCC = 20 mV.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.63 V (typ) at 25°C; ±0.15 V over −40°C to +85°C - ensures reliable 5 V rail monitoring with margin against ripple. |
| Supply Current | 12 μA (typ) at VCC < 3.6 V, −40°C to +85°C - enables battery-backed or ultra-low-power portable designs. |
| Reset Timeout | 140–460 ms (min–max) over −40°C to +85°C - provides sufficient stabilization time before microprocessor release. |
| VCC Operating Range | 1.0 V to 5.5 V - allows valid reset assertion even during deep brownout conditions down to 1 V. |
| MR Input Glitch Immunity | 100 ns (typ) - rejects noise spikes on manual reset line without external filtering. |
| RESET Output Type | Push-pull active-low - drives CMOS inputs directly; no external pull-up required. |
| Temperature Range | −40°C to +125°C - qualified for under-hood automotive and industrial control environments. |
Pinout & Package
ADM6711LAKS-REEL is housed in 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.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (GND) | Ground Reference | 0 V reference for all internal comparators and logic; must be connected to system ground plane. |
| 2 (RESET) | Active-Low Reset Output | Push-pull CMOS output asserted low during power-up/brownout; releases high after timeout completes. |
| 3 (MR) | Manual Reset Input | Active-low debounced input; holds RESET low while asserted and extends reset for 240 ms after release. |
| 4 (VCC) | Monitored Supply Voltage | Input for 5 V rail monitoring; also powers internal circuitry; operates down to 1.0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Precision Reset Threshold | 4.63 V ±0.15 V over full temperature range - matches 5 V supply tolerance and avoids false resets due to nominal ripple. |
| Ultra-Low Quiescent Current | 12 μA typical - reduces standby power in always-on systems such as telematics or sensor nodes. |
| Glitch-Immune MR Input | 100 ns rejection window - eliminates need for RC filtering on front-panel reset buttons in noisy environments. |
| Brownout Detection Down to 1 V | Valid RESET assertion at VCC ≥ 1.0 V - ensures deterministic behavior during catastrophic supply collapse. |
| SC70 Space Efficiency | 2.2 mm × 1.35 mm footprint - saves board area in compact modules like engine control units or portable test equipment. |

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, open-drain output, 140 ms timeout, 1.8–5.5 V VCC range - requires external pull-up resistor. | Designed for space-constrained consumer electronics; lacks −40°C to +125°C qualification. | Select when cost sensitivity outweighs automotive temperature range and push-pull simplicity. |
| TPS3808G33DBVR | 3.3 V threshold (not 4.63 V), push-pull output, 200 ms timeout, 0.8–6.0 V VCC - mismatched threshold for 5 V monitoring. | Optimized for 3.3 V SoCs; unsuitable for direct 5 V rail supervision without external divider. | Choose only if redesigning supply architecture to 3.3 V core logic and accepting recalibration effort. |
Compared with MAX6326US46D3+T and TPS3808G33DBVR, the ADM6711LAKS-REEL uniquely combines 4.63 V precision threshold, −40°C to +125°C operation, push-pull drive, and 12 μA quiescent current in SC70 - making it the sole option meeting full automotive ECU reset integrity requirements without layout or BOM changes.

FAQ
What is the exact reset threshold voltage of the ADM6711LAKS-REEL and how does it vary with temperature?
The ADM6711LAKS-REEL has a nominal reset threshold of 4.63 V at 25°C, with a guaranteed range 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. Its 30 ppm/°C temperature coefficient ensures minimal drift across operating conditions, making it suitable for precise 5 V rail monitoring in automotive and industrial applications where supply tolerance margins are tight.
Does the ADM6711LAKS-REEL require an external pull-up resistor on its RESET pin?
No, the ADM6711LAKS-REEL features a push-pull RESET output, eliminating the need for an external pull-up resistor. This simplifies PCB layout and reduces BOM count compared to open-drain alternatives like the ADM6713 series. The output actively drives high (≥0.8×VCC) and low (≤0.3 V) without external components, ensuring robust interfacing with standard CMOS microcontrollers.
What is the minimum VCC voltage at which the ADM6711LAKS-REEL continues to assert a valid RESET signal?
The ADM6711LAKS-REEL guarantees valid RESET assertion down to VCC = 1.0 V, as specified in its absolute maximum ratings and functional description. Below 0.8 V, the output enters high-impedance state; therefore, for full-rail validity, the device remains operational and asserts RESET reliably across its entire 1.0 V to 5.5 V supply range - critical for brownout detection in automotive and battery-backed systems.
How does the manual reset (MR) input of the ADM6711LAKS-REEL handle noise and short pulses?
The MR input of the ADM6711LAKS-REEL incorporates internal debounce logic that rejects transients shorter than 100 ns (typical) and guarantees recognition of pulses ≥1 μs. This eliminates susceptibility to contact bounce or EMI on front-panel switches and permits direct connection to noisy digital signals without external RC filtering - a key reliability feature in industrial HMI and automotive switch interfaces.
Is the ADM6711LAKS-REEL RoHS compliant and what is its packaging format?
Yes, the ADM6711LAKS-REEL is RoHS compliant (as indicated by the "Z" suffix variant naming convention in Analog Devices' ordering guide). It is supplied in tape-and-reel format (REEL) with 10,000 units per reel, housed in a Pb-free 4-lead SC70 (KS-4) package with JEDEC-standard dimensions and moisture sensitivity level (MSL) 1 - suitable for standard SMT reflow processes without special handling.
