Product details
Overview
ADM810LARTZ-REEL7 from Analog Devices is a microprocessor supervisory circuit with push-pull active-high RESET output, 4.63 V reset threshold, and operation down to 1.0 V VCC. It provides 240 ms (typical) power-on reset timeout, consumes only 17 μA at 3.6 V, and is qualified for −40°C to +125°C industrial/automotive environments. Used in embedded controllers to ensure reliable boot sequencing during brownout conditions.
For engineers reviewing the ADM810LARTZ-REEL7 datasheet, ADM810LARTZ-REEL7 pinout, ADM810LARTZ-REEL7 application, or ADM810LARTZ-REEL7 equivalent, key selection criteria include reset polarity (active-high), SOT-23-3 package compatibility, temperature range compliance, supply voltage monitoring accuracy, and low-quiescent-current operation in battery-backed systems.
Technical Context
The ADM810LARTZ-REEL7 integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms reset timer. Its active-high push-pull RESET output drives directly into CMOS inputs without external pull-up components.
It operates across full VCC range of 1.0 V to 5.5 V, maintains reset assertion until VCC exceeds 4.63 V ±3%, and sustains functional reset behavior even as VCC decays to 1.0 V - enabling robust brownout detection in wide-input-power systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.63 V (±3% over −40°C to +125°C); ensures reliable reset release only after stable 5 V rail establishment. |
| Reset Timeout | 240 ms typical; holds microprocessor in reset long enough for clock stabilization and memory initialization. |
| Supply Current | 17 μA at VCC < 3.6 V; enables integration into always-on, ultra-low-power monitoring paths. |
| VCC Operating Range | 1.0 V to 5.5 V; supports reset assertion during deep brownout and operation on partially discharged backup rails. |
| Output Type | Push-pull active-high RESET; eliminates need for external pull-up resistor and simplifies interface to 3.3 V/5 V logic. |
| Temperature Range | −40°C to +125°C; qualified for under-hood automotive, industrial PLC, and high-reliability embedded applications. |
Pinout & Package
ADM810LARTZ-REEL7 uses a 3-lead SOT-23 (RT-3) package with gull-wing leads, 1.3 mm × 2.9 mm footprint, and JEDEC TO-236-AB compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (GND) | Ground reference | 0 V return path for internal comparator and output driver; must be low-impedance connection to system ground plane. |
| 2 (RESET) | Active-high push-pull output | Drives high when VCC ≥ 4.63 V and timer expires; sinks/source current per spec; connects directly to µP RESET pin. |
| 3 (VCC) | Monitored supply input | Primary power rail being supervised; also powers internal circuitry; valid operation starts at 1.0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune reset comparator | Rejects fast transients ≤100 mV overdrive for up to 400 µs; prevents spurious resets during EFT events. |
| Precision threshold tolerance | ±3% over full temperature range; reduces risk of premature release or late assertion vs. nominal 5 V supply. |
| Low-voltage reset hold | Asserts RESET down to VCC = 1.0 V; guarantees reset remains active through deep undervoltage conditions. |
| Ultra-low quiescent current | 17 μA max at 3.6 V; extends battery life in always-connected supervisory functions without burdening power budget. |
| Industrial temperature grade | −40°C to +125°C operation; validated for extended thermal cycling in engine control units and motor drives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD2T-T | 4.63 V threshold, active-low push-pull output, same SOT-23-3 package, 1.2 μA higher quiescent current (18.2 μA). | Requires inverted logic handling at MCU reset pin; not drop-in for active-high designs. | Select only if redesign accommodates active-low reset and board layout allows minor current budget increase. |
| TPS3808G33DBVR | 3.3 V threshold (not 4.63 V), adjustable delay option, 1.5 μA typical IQ, SOT-23-6 package with enable pin. | Cannot replace 5 V rail supervision without external resistor divider; requires PCB redesign due to 6-pin footprint. | Use only for new designs targeting 3.3 V domains with programmable delay needs; not suitable for direct ADM810LARTZ-REEL7 replacement. |
Compared with MAX809TRD2T-T and TPS3808G33DBVR, ADM810LARTZ-REEL7 uniquely delivers active-high reset, exact 4.63 V threshold, and SOT-23-3 compatibility - making it the only option requiring zero hardware changes for legacy 5 V microcontroller reset circuits.

FAQ
What is the reset output polarity of ADM810LARTZ-REEL7?
The ADM810LARTZ-REEL7 features an active-high push-pull RESET output. When VCC falls below 4.63 V, RESET goes low; when VCC rises above the threshold and the internal timer expires (240 ms typical), RESET goes high. This eliminates the need for an external pull-up resistor and simplifies interface to MCUs expecting active-high reset signals - a key differentiator from the open-drain ADM803 or active-low ADM809 variants.
Does ADM810LARTZ-REEL7 support operation below 2.0 V VCC?
Yes, ADM810LARTZ-REEL7 remains fully functional down to VCC = 1.0 V. Its reset comparator continues asserting RESET until VCC exceeds 4.63 V, and its internal circuitry operates reliably across the full 1.0 V to 5.5 V range. This capability ensures deterministic reset behavior during severe brownout conditions where other supervisors may lose functionality - critical for fail-safe operation in automotive and industrial systems.
What package type and dimensions does ADM810LARTZ-REEL7 use?
ADM810LARTZ-REEL7 uses a 3-lead SOT-23 (JEDEC TO-236-AB, package option RT-3) with gull-wing leads. Its footprint measures 1.3 mm × 2.9 mm, thickness is 1.02 mm max, and lead pitch is 0.95 mm. This compact, surface-mount package supports automated assembly and meets IPC-7351B standards for reflow compatibility and mechanical reliability in high-volume manufacturing.
How does ADM810LARTZ-REEL7 handle fast voltage transients on VCC?
ADM810LARTZ-REEL7 incorporates a glitch-immune reset comparator that rejects transients up to 100 mV overdrive for durations ≤400 µs (per Figure 11). This design prevents false resets caused by EFT bursts, switching noise, or load-dump spikes - verified across the full −40°C to +125°C range. Unlike basic reset ICs, it does not require external RC filtering to meet IEC 61000-4-4 Level 3 immunity requirements.
Is ADM810LARTZ-REEL7 RoHS compliant and halogen-free?
Yes, ADM810LARTZ-REEL7 is RoHS compliant (indicated by the "Z" suffix) and meets JEDEC JS709C halogen-free requirements. The device uses matte tin lead finish, Pb-free solderable terminations, and green molding compound. Full compliance documentation - including test reports and material declarations - is available from Analog Devices' product page and Aetrix Electronics' quality portal upon request.
