Product details
Overview
ADM810ZAKSZ-REEL7 from Analog Devices is a microprocessor supervisory circuit with active-high push-pull RESET output, 2.32 V reset threshold (±0.07 V over −40°C to +125°C), 140–460 ms power-on reset timeout, 17 μA supply current, and SC70-3 package. It monitors VCC down to 1.0 V and asserts reset during power-up, brownout, and power-down in embedded controllers and instrumentation.
For engineers reviewing the ADM810ZAKSZ-REEL7 datasheet, ADM810ZAKSZ-REEL7 pinout, ADM810ZAKSZ-REEL7 application, or ADM810ZAKSZ-REEL7 equivalent, key selection criteria include reset polarity (active-high), threshold accuracy at extended temperature, low quiescent current for battery-sensitive designs, and compatibility with 1.8–5.5 V supply rails.
Technical Context
The ADM810ZAKSZ-REEL7 integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms (typical) reset timer. Its reference circuit maintains stable threshold performance across −40°C to +125°C, enabling reliable operation in automotive and industrial environments where supply transients and wide thermal swings occur.
It features push-pull RESET output capable of sourcing 150 μA at 1.8 V < VCC < VTH(min), with logic high level ≥0.8×VCC and low level ≤0.4 V under 3.2 mA sink. The device remains functional with VCC as low as 1.0 V, ensuring valid reset assertion during deep brownout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.32 V (typical), ±0.07 V over −40°C to +125°C - ensures accurate detection of 2.5 V rail collapse before microprocessor malfunction. |
| Supply Current | 17 μA (typical at VCC < 3.6 V, −40°C to +85°C) - enables integration into always-on, battery-backed systems without significant drain. |
| Reset Timeout | 140–460 ms (−40°C to +85°C), 100–840 ms (+85°C to +125°C) - provides sufficient hold time for slow-ramping 2.5 V/3.3 V supplies and FPGA configuration. |
| VCC Operating Range | 1.0 V to 5.5 V - supports monitoring of 1.8 V, 2.5 V, 3.3 V, and 5 V rails with same device variant. |
| RESET Output Type | Active-high push-pull - eliminates need for external pull-up resistor and drives CMOS/TTL inputs directly. |
| Reset Assertion Down to | VCC = 1.0 V - guarantees reset remains asserted through deep undervoltage events common in power-loss recovery. |
Pinout & Package
ADM810ZAKSZ-REEL7 uses a 3-lead SC70 (KS-3) package, 2.00 mm × 1.25 mm × 0.95 mm, RoHS-compliant, with gull-wing leads and 0.65 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Monitored supply input - connects directly to 2.5 V rail being supervised; must be decoupled locally. |
| 2 | RESET | Active-high push-pull output - drives microprocessor RESET# pin (inverted logic) or system enable line without external components. |
| 3 | GND | Ground reference - requires low-impedance connection to system ground plane to maintain noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune comparator | Rejects fast VCC transients up to 100 mV overdrive for ≤350 μs - prevents spurious resets during switching noise. |
| Precision voltage reference | 30 ppm/°C tempco - maintains threshold stability across automotive temperature range without calibration. |
| Extended VCC range | Operates down to 1.0 V - enables use in ultra-low-voltage backup domains and energy-harvesting systems. |
| Low-temperature drift | Threshold variation ≤ ±0.10 V over −40°C to +125°C - reduces design margin requirements for critical reset timing. |
| RoHS-compliant packaging | SC70-3 (KS-3) with bottom marking M6U - supports automated optical inspection and lead-free reflow profiles. |
Applications
| Industrial PLC Controller | Medical Sensor Node |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809ZTR | 2.32 V threshold, SOT-23-3, 1.2 μA max supply current, but only specified over −40°C to +85°C. | Limited to commercial/industrial ambient; not rated for full automotive temperature range. | Prefer ADM810ZAKSZ-REEL7 when operation above +85°C or guaranteed 125°C performance is required. |
| TPS3808G12DBVR | 1.2 V threshold (not 2.32 V); adjustable via external resistor; 1.8 μA typical supply current; 200 ms fixed timeout. | Requires external components for 2.32 V setting; lacks factory-trimmed precision and extended-temp qualification. | Choose ADM810ZAKSZ-REEL7 for drop-in replacement of fixed-threshold designs without layout changes or calibration. |
Compared with MAX809ZTR and TPS3808G12DBVR, ADM810ZAKSZ-REEL7 delivers tighter threshold accuracy over full −40°C to +125°C range, lower temperature coefficient, and guaranteed push-pull drive strength at low VCC - making it optimal for safety-critical and high-reliability 2.5 V system supervision.

FAQ
What is the reset polarity and output type of ADM810ZAKSZ-REEL7?
The ADM810ZAKSZ-REEL7 features an active-high push-pull RESET output. Unlike open-drain variants (e.g., ADM803), it does not require an external pull-up resistor and can directly drive CMOS or TTL inputs. This simplifies PCB layout and improves noise immunity in noisy environments.
What is the exact reset threshold voltage for ADM810ZAKSZ-REEL7 and how does it vary with temperature?
The ADM810ZAKSZ-REEL7 has a nominal reset threshold of 2.32 V at 25°C, with guaranteed range of 2.25 V to 2.38 V at −40°C to +85°C and 2.22 V to 2.42 V at −40°C to +125°C. Its temperature coefficient is 30 ppm/°C, ensuring minimal drift across automotive and industrial operating conditions.
Can ADM810ZAKSZ-REEL7 monitor a 2.5 V supply rail reliably?
Yes. With a 2.32 V threshold, ADM810ZAKSZ-REEL7 is specifically optimized for 2.5 V rail supervision. Its tight tolerance (±0.07 V at 25°C) and low tempco ensure reset assertion occurs before the 2.5 V rail falls below the minimum operating voltage of most 2.5 V microcontrollers and peripherals.
What is the minimum VCC voltage at which ADM810ZAKSZ-REEL7 continues to assert RESET?
The ADM810ZAKSZ-REEL7 maintains valid RESET assertion down to VCC = 1.0 V. Below this, the internal circuitry cannot guarantee correct logic levels; however, at 1.0 V, the device still sources/sinks sufficient current to hold downstream logic in reset, supporting graceful shutdown in deep brownout scenarios.
Is ADM810ZAKSZ-REEL7 RoHS-compliant and what package does it use?
Yes, ADM810ZAKSZ-REEL7 is RoHS-compliant (denoted by "Z" in the part number) and packaged in a 3-lead SC70 (KS-3) outline: 2.00 mm × 1.25 mm × 0.95 mm, with gull-wing leads and 0.65 mm pitch. It is compatible with standard reflow soldering profiles for lead-free assembly.
