Product details
Overview
ADM810MARTZ-REEL7 from Analog Devices is a microprocessor supervisory circuit with push-pull active-high RESET output, 4.38 V reset threshold, −40°C to +125°C operating temperature range, 17 μA supply current, and SOT-23-3 package. It monitors VCC in embedded controllers and ensures reliable power-on reset assertion for 240 ms (typical) during system startup.
For engineers reviewing the ADM810MARTZ-REEL7 datasheet, ADM810MARTZ-REEL7 pinout, ADM810MARTZ-REEL7 application, or ADM810MARTZ-REEL7 equivalent, key selection criteria include reset polarity (active-high), minimum VCC operation down to 1.0 V, precision threshold tolerance (±2.5% over full temp range), and compatibility with 3 V/5 V microprocessor systems requiring robust brownout detection.
Technical Context
The ADM810MARTZ-REEL7 integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms reset timeout timer. Its reset assertion remains valid even as VCC drops to 1.0 V, enabling stable reset signaling during deep brownout conditions.
Unlike open-drain variants (e.g., ADM803), the ADM810MARTZ-REEL7 features a push-pull output capable of sourcing 150 μA at 1.8 V < VCC < VTH(min), eliminating need for external pull-up resistors while maintaining logic-level compatibility across 3 V and 5 V domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.38 V nominal; ±2.5% over −40°C to +125°C - ensures accurate detection of 4.5 V supply droop before microprocessor malfunction. |
| Supply Current | 17 μA typical at VCC < 3.6 V - enables integration into battery-powered or ultra-low-power embedded systems without significant quiescent load. |
| Reset Timeout | 240 ms typical power-up delay - holds microprocessor in reset long enough for clock stabilization and memory initialization. |
| Min Operating VCC | 1.0 V - guarantees functional reset assertion during severe brownout or slow power ramp-down, critical for fail-safe shutdown. |
| Output Type | Push-pull active-high - drives RESET line directly to VCC or GND without external components, simplifying PCB layout and reducing BOM count. |
| Temp Range | −40°C to +125°C - qualified for under-hood automotive, industrial motor control, and high-reliability embedded applications. |
Pinout & Package
ADM810MARTZ-REEL7 is housed in a 3-lead SOT-23-3 (RT-3) package per JEDEC TO-236-AB, with 1.3 mm × 2.9 mm footprint and 1.1 mm height. Pin 1 = VCC, Pin 2 = RESET (active-high push-pull), Pin 3 = GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Supply Input | Monitored power rail input; device operates and asserts reset when VCC falls below 4.38 V threshold. |
| RESET (Pin 2) | Active-High Output | Drives high during normal operation; pulls low for 240 ms after power-up or brownout until VCC stabilizes above threshold. |
| GND (Pin 3) | Ground Reference | Common return path for internal comparator and output driver; must be low-impedance connection to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune comparator | Rejects transients ≤100 μs duration at VCC, preventing false resets from switching noise or ESD coupling. |
| Precision threshold accuracy | ±2.5% over full −40°C to +125°C range - eliminates need for external trimming or calibration in production systems. |
| Low-voltage reset operation | Functional down to VCC = 1.0 V - ensures deterministic reset behavior during catastrophic supply collapse. |
| Push-pull output drive | Sources 150 μA at 1.8 V < VCC < VTH(min) - interfaces directly with CMOS inputs without pull-up resistor or level-shifter. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS3808G33DBVR | 3.3 V fixed threshold; 350 ms reset timeout; 2.9 μA quiescent current; SOT-23-5 package. | Designed for 3.3 V systems only; longer timeout may delay MCU boot in time-critical applications. | Select when lower power and tighter 3.3 V threshold tolerance (±0.5%) are prioritized over flexibility in threshold voltage. |
| MAX809SEUR+T | 3.08 V threshold; 140 ms min timeout; open-drain output; SOT-23-3 package. | Requires external pull-up; incompatible with active-high logic requirements without inversion. | Choose only if system design already uses open-drain reset architecture and 3.08 V monitoring suffices. |
Compared with TPS3808G33DBVR and MAX809SEUR+T, the ADM810MARTZ-REEL7 offers unique combination of 4.38 V threshold, active-high push-pull output, and 1.0 V operational floor - making it optimal for 5 V microcontroller systems needing deterministic reset behavior under deep brownout.

FAQ
What is the reset polarity of ADM810MARTZ-REEL7?
The ADM810MARTZ-REEL7 provides an active-high RESET output: the pin is driven high during normal operation and pulled low for 240 ms (typical) after power-up or when VCC falls below the 4.38 V threshold. This differs from ADM803 (open-drain active-low) and ADM809 (push-pull active-low), making ADM810MARTZ-REEL7 ideal for systems requiring direct interface with active-high reset inputs.
Does ADM810MARTZ-REEL7 require an external pull-up resistor?
No, ADM810MARTZ-REEL7 does not require an external pull-up resistor because it features a push-pull output stage. The RESET pin actively drives high or low depending on VCC status, eliminating dependency on external components - unlike the ADM803 variant which mandates a pull-up for proper logic-level definition.
What is the minimum supply voltage at which ADM810MARTZ-REEL7 remains functional?
The ADM810MARTZ-REEL7 remains fully functional down to VCC = 1.0 V, maintaining accurate reset assertion even during severe brownout conditions. This capability is confirmed across its full operating temperature range (−40°C to +125°C) and enables fail-safe behavior in systems where supply collapse must trigger controlled shutdown before data corruption occurs.
How does the 240 ms reset timeout of ADM810MARTZ-REEL7 benefit system reliability?
The 240 ms reset timeout in ADM810MARTZ-REEL7 ensures the microprocessor remains held in reset long enough for oscillator stabilization, power supply settling, and internal register initialization - all critical before instruction fetch begins. This fixed, temperature-compensated delay prevents premature release from reset that could cause erratic boot behavior or memory corruption in demanding embedded environments.
Is ADM810MARTZ-REEL7 RoHS compliant and what package does it use?
Yes, ADM810MARTZ-REEL7 is RoHS compliant (indicated by the "Z" suffix) and packaged in a 3-lead SOT-23-3 (RT-3) outline per JEDEC TO-236-AB. Its compact 1.3 mm × 2.9 mm footprint supports high-density PCB layouts, and the lead finish meets J-STD-020 moisture sensitivity level 1 requirements for standard reflow assembly.
