Product details
Overview
ADM6711TAKS-REEL from Analog Devices is a precision microprocessor supervisory circuit in 4-lead SC70 packaging, designed to monitor 3.0 V supply rails with a factory-trimmed reset threshold of 3.08 V (typ), 140 ms minimum reset timeout, push-pull active-low RESET output, and manual reset input with 1 μs minimum pulse width. It operates across −40°C to +125°C and consumes only 12 μA typical supply current, enabling reliable power-on reset in space-constrained portable microcontroller systems.
For engineers reviewing the ADM6711TAKS-REEL datasheet, ADM6711TAKS-REEL pinout, ADM6711TAKS-REEL application, or ADM6711TAKS-REEL equivalent, key selection criteria include its fixed 3.08 V reset threshold, SC70 package footprint, push-pull output eliminating external pull-up components, guaranteed reset assertion down to 1 V VCC, and immunity to sub-100 ns power supply glitches.
Technical Context
The ADM6711TAKS-REEL integrates a precision voltage reference, comparator with 30 ppm/°C temperature coefficient, debounced manual reset input (100 ns glitch rejection), and internal 240 ms typical reset timeout generator. Its push-pull RESET output drives logic directly without external components, supporting fast, clean transitions at up to 500 μA source/sink capability.
It monitors VCC continuously and asserts RESET when supply falls below 3.08 V (±5% over temperature), holding it active for ≥140 ms after VCC recovers above threshold. The MR input accepts logic-level or mechanical switch signals, with internal pull-up resistance of 10–20 kΩ and guaranteed response to pulses ≥1 μs wide.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.08 V (typ) at 25°C; ±5% over −40°C to +125°C - ensures reliable detection of 3.0 V rail brownout before system instability. |
| Reset Timeout | 140 ms (min); 240 ms (typ) - provides sufficient stabilization time for 3.0 V-powered microcontrollers before release from reset. |
| Supply Current | 12 μA (typ) at VCC < 3.6 V, −40°C to +85°C - enables multi-year battery operation in low-power embedded sensors. |
| Operating Voltage Range | 1.0 V to 5.5 V - supports reset assertion even during deep brownout down to 1 V VCC, critical for fail-safe shutdown. |
| MR Input Pulse Width | ≥1 μs minimum - accommodates standard GPIO toggles and mechanical switch bounce without false triggering. |
| Glitch Immunity | 100 ns minimum rejection - prevents spurious resets from EMI or switching noise on 3.0 V supply lines. |
| Output Type | Push-pull active-low RESET - eliminates need for external pull-up resistor, reducing BOM count and PCB area. |
Pinout & Package
ADM6711TAKS-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 - optimized for high-density portable PCB layouts.
| 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 accuracy. |
| 2 RESET | Active-low push-pull output | Drives microcontroller /RESET pin directly; sinks 1.2 mA at 0.3 V or sources 500 μA at 0.8×VCC - no external components required. |
| 3 MR | Debounced manual reset input | Active-low; internally pulled up (10–20 kΩ); ignores transients <100 ns; triggers full reset cycle when asserted ≥1 μs. |
| 4 VCC | Monitored supply input | Connects to 3.0 V rail being supervised; powers internal circuitry and defines reset threshold reference point. |
Key Features
| Feature | Design Value |
|---|---|
| Precision 3.08 V threshold | Factory-trimmed for 3.0 V systems; ±5% tolerance over full −40°C to +125°C range ensures consistent brownout detection. |

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, SOT-23-3 package, open-drain output, 1.6 μA max supply current | Requires external pull-up resistor; lacks manual reset input; lower current draw but no MR functionality | Select when board space is constrained to 3-pin layout and manual reset is unnecessary |
| TPS3808G33DBVR | 3.3 V threshold (not 3.08 V), SOT-23-6 package, push-pull output, 16 μA typical supply current | Higher threshold risks missing early 3.0 V brownout; extra pins for watchdog and enable not used in basic reset-only designs | Select only if 3.3 V rail supervision is acceptable and 6-pin footprint is available |
Compared with MAX6326UT31D3+T and TPS3808G33DBVR, ADM6711TAKS-REEL uniquely combines 3.08 V precision threshold, push-pull output, manual reset input, and SC70 footprint - making it the only option that satisfies all four requirements simultaneously for compact 3.0 V microcontroller reset applications.

FAQ
What is the exact reset threshold voltage of ADM6711TAKS-REEL and how does it vary with temperature?
The ADM6711TAKS-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 specification is factory-trimmed and calibrated per unit, ensuring precise compatibility with 3.0 V supply rails across full industrial temperature operation. The ADM6711TAKS-REEL maintains this accuracy via an internal reference with 30 ppm/°C temperature coefficient.
Does ADM6711TAKS-REEL require an external pull-up resistor on the RESET pin?
No, ADM6711TAKS-REEL does not require an external pull-up resistor because it features a push-pull RESET output stage. The ADM6711TAKS-REEL actively drives the RESET pin low during assertion and high during deassertion, delivering 500 μA source current at 0.8×VCC - enabling direct connection to microcontroller reset inputs without additional components. This distinguishes ADM6711TAKS-REEL from open-drain alternatives like the ADM6713 series.
What is the minimum pulse width required on the MR pin to trigger a valid reset with ADM6711TAKS-REEL?
The ADM6711TAKS-REEL requires a minimum MR input pulse width of 1 μs to guarantee reset initiation. Its internal debounce circuit rejects transients shorter than 100 ns (typical), ensuring immunity to contact bounce or electrical noise. When MR is asserted for ≥1 μs, the ADM6711TAKS-REEL holds RESET low for the full 240 ms typical timeout period - providing deterministic manual reset behavior compatible with both mechanical switches and digital GPIO signals.
Can ADM6711TAKS-REEL operate reliably when the monitored VCC drops below 2.0 V?
Yes, ADM6711TAKS-REEL asserts RESET down to VCC = 1.0 V and remains functional across its full 1.0 V to 5.5 V operating range. Below 1.0 V, the device ceases operation, but the RESET output remains latched low until VCC rises above the 3.08 V threshold. This 1 V minimum VCC operation ensures fail-safe reset assertion during deep brownout conditions - a verified capability documented in the ADM6711TAKS-REEL absolute maximum ratings and functional specifications.
What package type and dimensions does ADM6711TAKS-REEL use, and is it compatible with standard SC70 footprints?
ADM6711TAKS-REEL uses the 4-lead SC70 (KS-4) package with body dimensions of 2.20 mm × 1.35 mm × 0.9 mm and 0.65 mm lead pitch. Its outline fully complies with EIAJ SC82 standards except for pin 2 width, and it is pin-compatible with industry-standard SC70 footprints. The ADM6711TAKS-REEL's coplanarity is specified at ≤0.10 mm, supporting reliable reflow soldering in high-volume SMT assembly processes.
