Product details
Overview
ADM6711MAKS-REEL7 from Analog Devices is a microprocessor supervisory circuit in 4-lead SC70 package, providing precision reset generation for 3 V supply monitoring with 4.38 V threshold, 140 ms minimum reset timeout, push-pull active-low RESET output, and manual reset input. It ensures reliable power-up sequencing in portable microcontroller systems operating from −40°C to +125°C.
For engineers reviewing the ADM6711MAKS-REEL7 datasheet, ADM6711MAKS-REEL7 pinout, ADM6711MAKS-REEL7 application, or ADM6711MAKS-REEL7 equivalent, key selection criteria include reset threshold accuracy over temperature, low 12 μA supply current, glitch immunity to 100 ns transients, and compatibility with 3 V rail supervision in space-constrained designs.
Technical Context
The ADM6711MAKS-REEL7 integrates a precision voltage reference, comparator, debounce logic, and push-pull output driver. Its reset assertion remains active until VCC rises above 4.38 V (typ) and sustains for ≥140 ms after crossing threshold, ensuring stable power supply ramp-up before processor release.
It features a debounced manual reset (MR) input with 1 μs minimum pulse width acceptance and 100 ns glitch rejection, plus power supply glitch immunity validated down to 20 mV overdrive. Reset output remains valid down to VCC = 1 V, supporting brownout detection in low-voltage operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.38 V (typ), ±0.13 V over −40°C to +85°C - precisely monitors 3 V supply rails with margin for tolerance and drift. |
| Reset Timeout Period | 140–460 ms - guarantees sufficient hold time for 3 V system stabilization before microprocessor exit from reset. |
| Supply Current | 12 μA (typ) at VCC < 3.6 V - enables multi-year battery life in portable and IoT edge devices. |
| Operating Voltage Range | 1.2 V to 5.5 V - supports supervision of 3 V systems while remaining functional during deep brownout conditions. |
| MR Input Glitch Immunity | 100 ns - rejects noise on manual reset lines without external RC filtering in typical PCB layouts. |
| Reset Output Type | Push-pull active-low - eliminates need for external pull-up resistor, simplifying BOM and reducing board area. |
| Temperature Range | −40°C to +125°C - qualified for under-hood automotive, industrial control, and high-reliability embedded applications. |
Pinout & Package
ADM6711MAKS-REEL7 is housed in a 4-lead SC70 (KS-4) package measuring 2.20 mm × 1.35 mm × 0.9 mm, optimized for ultra-compact PCB layouts and automated SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 GND | Ground Reference | 0 V return path for all internal circuitry; must be connected directly to system ground plane for noise immunity. |
| 2 RESET | Active-Low Reset Output | Push-pull CMOS output asserted low during power-up, brownout, or MR activation; drives microprocessor /RESET pin directly. |
| 3 MR | Manual Reset Input | Debounced active-low input; accepts ≥1 μs pulses and ignores <100 ns glitches; floats high when unused. |
| 4 VCC | Monitored Supply Input | Input voltage source being supervised; powers internal circuitry and sets reference for threshold detection. |
Key Features
| Feature | Design Value |
|---|---|
| Precision 4.38 V threshold | ±2.9% max deviation over −40°C to +125°C - enables accurate 3 V rail monitoring without external calibration. |
| 140 ms min reset timeout | Guaranteed hold time ensures CPU clock and memory initialization complete before release from reset. |
| 12 μA supply current | Reduces quiescent load on battery-backed or energy-harvested systems by >50% vs. legacy supervisors. |
| Reset assertion down to 1 V VCC | Enables fail-safe shutdown detection even during severe undervoltage events below normal operating range. |
| SC70 package footprint | 0.9 mm height and 2.2 mm × 1.35 mm area - fits into dense MCU subsystems where space is constrained. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326UT43D3+ | 4.33 V threshold, 200 ms timeout, 1.8–5.5 V operation, SOT-23-3 package | Lacks manual reset input; requires external pull-up for open-drain output | Choose when MR functionality is unnecessary and board space permits SOT-23-3 instead of SC70. |
| TPS3808G33DBVR | 3.3 V threshold (not 4.38 V), 200 ms timeout, 0.8–6 V operation, SOT-23-5 package | Higher threshold mismatch for 3 V rail supervision; includes watchdog timer not present in ADM6711MAKS-REEL7 | Choose only if system requires integrated watchdog; otherwise, threshold inaccuracy risks premature reset release. |
Compared with MAX6326UT43D3+ and TPS3808G33DBVR, ADM6711MAKS-REEL7 delivers exact 4.38 V threshold alignment for 3 V supplies, integrated MR debouncing, and smallest footprint-making it optimal for compact, high-precision reset supervision without added components or timing uncertainty.

FAQ
What is the exact reset threshold voltage of ADM6711MAKS-REEL7 and how does it vary with temperature?
The ADM6711MAKS-REEL7 has a nominal reset threshold of 4.38 V at 25°C, with a guaranteed range of 4.25 V to 4.50 V over −40°C to +85°C and 4.20 V to 4.56 V over 85°C to +125°C. Its temperature coefficient is 30 ppm/°C, resulting in ≤±1.2% total variation across the full industrial temperature range - ensuring consistent 3 V rail supervision without recalibration.
Does ADM6711MAKS-REEL7 require an external pull-up resistor on the RESET pin?
No, ADM6711MAKS-REEL7 features a push-pull RESET output, so no external pull-up resistor is required. This simplifies design, reduces BOM cost, and avoids potential conflicts when driving multiple loads. In contrast, the ADM6713 variant uses an open-drain output and does require an external pull-up.
What is the minimum pulse width accepted on the MR pin of ADM6711MAKS-REEL7?
The MR pin of ADM6711MAKS-REEL7 accepts a minimum pulse width of 1 μs for reliable reset initiation. Pulses shorter than 100 ns are rejected by internal debounce circuitry, making the input robust against EMI and contact bounce in mechanical switch implementations.
Can ADM6711MAKS-REEL7 operate reliably below 2.5 V supply voltage?
Yes - ADM6711MAKS-REEL7 operates down to 1.2 V over its full temperature range (−40°C to +125°C), and reset assertion remains valid down to VCC = 1 V. This enables brownout detection in low-voltage systems such as those powered by single-cell Li-ion or supercapacitors.
What package type and dimensions does ADM6711MAKS-REEL7 use?
ADM6711MAKS-REEL7 uses the 4-lead SC70 (KS-4) package, with dimensions of 2.20 mm × 1.35 mm × 0.9 mm. Its small footprint and low profile make it ideal for high-density PCBs in portable and automotive electronics where board space is at a premium.
