Product details
Overview
ADM810ZARTZ-REEL 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), 17 μA supply current, and 240 ms typical power-on reset timeout. It monitors 2.5 V–3.3 V supply rails in embedded controllers and portable instrumentation where low-power, high-accuracy voltage supervision is required.
For engineers reviewing the ADM810ZARTZ-REEL datasheet, ADM810ZARTZ-REEL pinout, ADM810ZARTZ-REEL application, or ADM810ZARTZ-REEL equivalent, key selection criteria include reset polarity (active-high), SOT-23-3 package compatibility, operation down to 1 V VCC, temperature-stable threshold (30 ppm/°C), and guaranteed reset assertion during brownout conditions.
Technical Context
The ADM810ZARTZ-REEL implements a precision bandgap-based voltage reference comparator with built-in glitch immunity, enabling reliable reset generation despite fast transients on VCC. Its internal timer ensures 240 ms minimum reset assertion after VCC rises above 2.32 V, with full functionality maintained down to VCC = 1.0 V.
This device belongs to the ADM803/ADM809/ADM810 family and uses a fixed-threshold architecture-no external resistor network or configuration pins are required. The push-pull output drives logic inputs directly without pull-up components, simplifying interface design in space-constrained 3 V systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.32 V (typical at 25°C); ±0.07 V tolerance over −40°C to +125°C ensures robust detection of 2.5 V rail collapse. |
| Supply Current | 17 μA (typical at VCC < 3.6 V, −40°C to +85°C); enables battery-powered operation for >10 years in low-duty-cycle systems. |
| Reset Timeout | 240 ms (typical); holds microprocessor in reset until power stabilizes, preventing premature execution during power-up. |
| VCC Operating Range | 1.0 V to 5.5 V; guarantees functional reset assertion even during deep brownout or partial power loss. |
| Output Type | Active-high push-pull; eliminates need for external pull-up resistor and supports direct CMOS/TTL interfacing. |
| Temperature Coefficient | 30 ppm/°C; minimizes threshold drift across industrial temperature range, reducing false resets. |
| Reset Output Low Voltage | 0.3 V (max at ISINK = 1.2 mA, VCC = VTH min); ensures solid logic-low state for compatible microcontroller reset inputs. |
| Reset Output High Voltage | 0.8 × VCC (min at ISOURCE = 150 μA, 1.8 V < VCC < VTH min); provides sufficient noise margin for 3.3 V logic interfaces. |
Pinout & Package
ADM810ZARTZ-REEL is housed in a 3-lead SOT-23 (RT-3) package per JEDEC TO-236-AB standard, with 1.3 mm × 2.9 mm footprint and 0.95 mm height. Pin 1 = VCC, Pin 2 = RESET (active-high push-pull), Pin 3 = GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC) | Supply Input | Monitored voltage rail input; device operates and asserts reset when VCC falls below 2.32 V. |
| 2 (RESET) | Active-High Push-Pull Output | Drives high during normal operation; pulls low for 240 ms after power-up or brownout recovery. |
| 3 (GND) | Ground Reference | 0 V reference for internal comparator and output stage; must be connected to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Precision Reset Threshold | 2.32 V with ±0.07 V tolerance over −40°C to +125°C enables accurate supervision of 2.5 V supplies. |
| Ultra-Low Quiescent Current | 17 μA typical allows integration into always-on subsystems without compromising battery life. |
| Guaranteed Operation Down to 1 V | Continues asserting reset even as VCC collapses to 1.0 V, ensuring clean processor reset during severe brownout. |
| Built-in Glitch Immunity | Rejects fast VCC transients up to 100 mV overdrive, preventing spurious resets in noisy power environments. |
| Fixed-Timer Power-On Reset | 240 ms minimum timeout eliminates need for external RC timing components and associated layout area. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM809ZARTZ-REEL7 | Same 2.32 V threshold and SOT-23 package, but active-low push-pull output. | Requires inverted reset logic path or level-shifting interface for microcontrollers expecting active-high reset. | Select only if system design accommodates active-low reset signaling and no redesign of reset net is feasible. |
| MAX809TRD3T | 2.32 V threshold, active-high output, but higher 25 μA supply current and ±1.5% threshold accuracy (vs. ±3% for ADM810ZARTZ-REEL). | Less suitable for ultra-low-power battery applications; tighter threshold spec may increase cost without benefit in 2.5 V rail monitoring. | Prefer ADM810ZARTZ-REEL when sub-20 μA quiescent current and proven industrial temperature performance are mandatory. |
Compared with ADM809ZARTZ-REEL7, ADM810ZARTZ-REEL avoids level translation overhead; compared with MAX809TRD3T, it delivers lower power and broader temperature stability-critical for long-life embedded deployments where reset reliability cannot be compromised.

FAQ
What is the reset polarity and output structure of the ADM810ZARTZ-REEL?
The ADM810ZARTZ-REEL features an active-high push-pull RESET output. When VCC is above 2.32 V, RESET is driven high; when VCC falls below threshold or during power-up, RESET is actively pulled low for 240 ms (typical). This eliminates external pull-up resistors and ensures deterministic logic levels for microcontroller reset inputs. The ADM810ZARTZ-REEL does not use open-drain topology-its output stage sources and sinks current directly.
Does the ADM810ZARTZ-REEL operate reliably at temperatures beyond 85°C?
Yes, the ADM810ZARTZ-REEL is fully specified from −40°C to +125°C. Its 2.32 V reset threshold maintains ±0.07 V tolerance across this full range, and supply current remains ≤30 μA at 125°C. The device meets industrial-grade thermal performance requirements, making it suitable for under-hood automotive and high-ambient industrial applications where sustained operation above 85°C is required.
Can the ADM810ZARTZ-REEL supervise a 3.3 V supply rail?
Yes-the ADM810ZARTZ-REEL's 2.32 V reset threshold is intentionally selected to supervise 2.5 V and 3.3 V nominal rails. With its guaranteed operation down to 1.0 V VCC and 240 ms reset timeout, it detects brownout conditions on 3.3 V systems before critical logic voltage margins are violated. Its 30 ppm/°C temperature coefficient ensures minimal threshold drift across operating temperature, preserving timing margin integrity.
How does the ADM810ZARTZ-REEL handle fast transients on the VCC line?
The ADM810ZARTZ-REEL incorporates built-in glitch immunity in its reset comparator, rejecting transients up to 100 mV overdrive without triggering false resets. As shown in Figure 11 of the datasheet, it tolerates transient durations up to 350 μs at 10 mV overdrive-making it robust against switching noise, ESD coupling, and load-dump spikes common in embedded power systems. This feature is intrinsic to the comparator design and requires no external filtering.
Is the ADM810ZARTZ-REEL pin-compatible with other members of the ADM803/ADM809/ADM810 family?
Yes-ADM810ZARTZ-REEL shares identical 3-lead SOT-23 (RT-3) pinout with all ADM809 and ADM810 variants in that package, including VCC on Pin 1, RESET on Pin 2, and GND on Pin 3. However, reset polarity differs: ADM810 devices output active-high RESET, while ADM809 devices output active-low. Swapping them requires verification of downstream logic compatibility, as no electrical or mechanical adaptation is needed beyond signal-level validation.
