Product details
Overview
ADM6711ZAKSZ-REEL7 from Analog Devices is a precision microprocessor supervisory circuit in 4-lead SC70 packaging, designed to monitor 2.5 V supply rails with a factory-trimmed reset threshold of 2.32 V (typ), asserting active-low RESET for ≥140 ms after VCC rise, and supporting manual reset via debounced MR input. It delivers low-power operation (12 μA typ) and operates across −40°C to +125°C for industrial and automotive embedded systems.
For engineers reviewing the ADM6711ZAKSZ-REEL7 datasheet, ADM6711ZAKSZ-REEL7 pinout, ADM6711ZAKSZ-REEL7 application, or ADM6711ZAKSZ-REEL7 equivalent, key selection criteria include its push-pull RESET output, 2.32 V threshold accuracy over temperature, 100 ns glitch immunity, and compatibility with low-voltage microcontroller power-up sequencing.
Technical Context
The ADM6711ZAKSZ-REEL7 integrates a precision bandgap voltage reference, comparator with hysteresis, and a 240 ms (typ) internal timeout timer to ensure reliable power-on reset assertion. Its reset generator remains functional down to VCC = 1.0 V, enabling robust brownout detection in battery-backed or low-dropout regulator-fed systems.
It features a debounced manual reset input (MR) with guaranteed acceptance of ≥1 μs pulses and rejection of <100 ns transients, plus internal filtering that rejects supply glitches up to 1000 mV amplitude depending on duration - critical for noisy automotive or industrial power environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.32 V (typ) at 25°C; ±0.13 V over −40°C to +85°C - ensures accurate 2.5 V rail monitoring with margin for tolerance drift. |
| Reset Timeout | 140–460 ms (min–max) - guarantees sufficient hold time for microprocessor core and PLL stabilization before release. |
| Supply Current | 12 μA (typ) at VCC < 3.6 V - enables use in always-on, battery-powered IoT nodes without compromising runtime. |
| Operating Voltage Range | 1.0 V to 5.5 V - supports operation during deep brownout and allows monitoring of sub-2.5 V auxiliary rails. |
| Glitch Immunity | Rejects transients ≤100 ns - prevents spurious resets caused by switching noise or ESD coupling on VCC. |
| MR Input Pulse Width | ≥1 μs minimum - ensures compatibility with standard GPIO-driven reset buttons and logic-level control signals. |
| Output Type | Push-pull active-low RESET - eliminates need for external pull-up resistor, simplifying PCB layout and reducing BOM count. |
Pinout & Package
ADM6711ZAKSZ-REEL7 is housed in a 4-lead SC70 (KS-4) package - compact (2.2 mm × 1.35 mm), surface-mount, and RoHS-compliant - optimized for space-constrained portable and automotive modules.
| 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; initiates reset when pulled low ≥1 μs; internally pulled up - float if unused. |
| 4 (VCC) | Monitored Supply Input | Primary power rail under supervision; powers internal circuitry and sets reference for threshold comparison. |
Key Features
| Feature | Design Value |
|---|---|
| Precision Threshold Accuracy | ±3% over −40°C to +85°C - eliminates need for external trimming or calibration in production test. |
| Low-VCC Reset Assertion | Operates and asserts RESET down to VCC = 1.0 V - ensures deterministic reset behavior during severe undervoltage conditions. |
| Integrated Glitch Filtering | Rejects fast transients ≤100 ns on VCC - removes requirement for external RC filter networks in noisy environments. |
| Debounced Manual Reset | Hardware-debounced MR input with 1 μs minimum pulse width - avoids firmware-level debounce complexity and timing uncertainty. |
| Wide Temperature Range | Rated for −40°C to +125°C operation - qualified for under-hood automotive and industrial control applications. |
Applications
| Automotive Body Control Module | Industrial PLC I/O Subsystem |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326UT23+T | 2.32 V threshold, open-drain output, 1.2 μA quiescent current - lacks push-pull drive and MR debounce. | Requires external pull-up and software/hardware debounce for MR; better suited for ultra-low-power sleep-mode monitoring. | Select when minimizing standby current is primary, and system design accommodates open-drain logic level translation. |
| TPS3808G12DBVR | 1.22 V threshold (fixed), push-pull output, 1.8 μA IQ - not pin-compatible; requires redesign for 2.32 V monitoring. | Designed for 1.2 V–3.6 V supplies; no direct 2.32 V variant - necessitates recalculating voltage divider or selecting alternate family. | Choose only if migrating to TI ecosystem and adjusting supply architecture; not a drop-in replacement for ADM6711ZAKSZ-REEL7. |
Compared with MAX6326UT23+T and TPS3808G12DBVR, ADM6711ZAKSZ-REEL7 uniquely combines factory-trimmed 2.32 V threshold, push-pull output, hardware MR debounce, and full −40°C to +125°C qualification - enabling simpler, more robust reset implementation in 2.5 V microcontroller systems without layout or firmware compromises.

FAQ
What is the exact reset threshold voltage of ADM6711ZAKSZ-REEL7 and how does it vary with temperature?
The ADM6711ZAKSZ-REEL7 has a nominal reset threshold of 2.32 V at 25°C, with a guaranteed range of 2.25 V to 2.38 V over −40°C to +85°C and 2.22 V to 2.42 V over 85°C to +125°C. This variation is specified in Table 1 of the Rev. B datasheet and reflects the device's 30 ppm/°C temperature coefficient - ensuring predictable 2.5 V rail supervision across full industrial and automotive operating conditions. The ADM6711ZAKSZ-REEL7 maintains this accuracy without external calibration.
Does ADM6711ZAKSZ-REEL7 support manual reset, and what are the electrical requirements for the MR pin?
Yes, ADM6711ZAKSZ-REEL7 includes a debounced manual reset (MR) input that accepts active-low logic signals. The MR pin has VIH = 0.7 × VCC and VIL = 0.3 × VCC, with guaranteed recognition of pulses ≥1 μs and rejection of transients <100 ns. No external pull-up is required - the pin is internally biased. When MR is asserted, ADM6711ZAKSZ-REEL7 holds RESET low for 240 ms (typ) after MR returns high, providing consistent reset timing regardless of switch bounce or noise.
What is the supply current consumption of ADM6711ZAKSZ-REEL7 across its operating voltage and temperature range?
ADM6711ZAKSZ-REEL7 draws 12 μA (typ) at VCC < 3.6 V and TA = −40°C to +85°C, rising to 60 μA at 85°C to +125°C under the same conditions. At VCC = 1 V, current remains stable near 12 μA per Figure 5. This ultra-low quiescent current enables deployment in always-on battery-powered systems - such as medical wearables or remote sensors - where ADM6711ZAKSZ-REEL7 contributes minimally to total system leakage while maintaining full supervisory functionality.
Can ADM6711ZAKSZ-REEL7 operate reliably during power supply glitches, and what is its immunity specification?
Yes, ADM6711ZAKSZ-REEL7 incorporates internal filtering to reject fast supply transients. Its power supply glitch immunity is characterized in Figure 9: it ignores negative-going VCC excursions ≤100 ns in duration, regardless of amplitude, and tolerates larger glitches (e.g., 200 mV overdrive) up to ~350 ns. This hardens systems against ESD-induced supply noise, switching regulator ripple, and load dump events - a key reliability feature confirmed in the ADM6711ZAKSZ-REEL7 datasheet's Circuit Description section.
Is ADM6711ZAKSZ-REEL7 pin-compatible with other members of the ADM6711/ADM6713 family, and what output type does it use?
Yes, ADM6711ZAKSZ-REEL7 shares identical 4-lead SC70 (KS-4) pinout and footprint with all ADM6711 variants (e.g., ADM6711TAKSZ-REEL7) and ADM6713 variants. It uses a push-pull RESET output - unlike the open-drain ADM6713 versions - meaning ADM6711ZAKSZ-REEL7 drives both logic high and low actively, eliminating the need for an external pull-up resistor. This simplifies design and improves noise margin compared to open-drain alternatives.
