Product details
Overview
ADM810MARTZ-REEL from Analog Devices is a microprocessor supervisory circuit in 3-lead SOT-23 package, providing active-high push-pull reset output with 4.38 V threshold, 240 ms typical reset timeout, and operation down to 1.0 V VCC. It monitors supply voltage in embedded controllers and ensures reliable power-on reset for industrial microprocessor systems.
For engineers reviewing the ADM810MARTZ-REEL datasheet, ADM810MARTZ-REEL pinout, ADM810MARTZ-REEL application, or ADM810MARTZ-REEL equivalent, key selection criteria include reset polarity (active-high), push-pull drive capability, 4.38 V threshold accuracy over −40°C to +125°C, low 17 μA supply current, and SOT-23 footprint compatibility with space-constrained PCB layouts.
Technical Context
The ADM810MARTZ-REEL implements a precision bandgap-based voltage comparator with built-in glitch immunity to reject fast VCC transients up to 100 mV overdrive. Its internal timer generates a fixed 240 ms (typical) reset assertion after VCC rises above the 4.38 V threshold, ensuring stable microprocessor initialization.
It features a push-pull RESET output capable of sourcing 150 μA at 1.8 V < VCC < VTH(min) and sinking 1.2 mA at VCC = VTH(min), eliminating need for external pull-up resistors. The device operates across full VCC range of 1.0 V to 5.5 V and maintains reset functionality down to 1.0 V VCC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.38 V (typical), ±0.07 V over −40°C to +85°C - ensures accurate 4.4 V supply monitoring without premature or delayed reset assertion. |
| Reset Timeout | 240 ms (typical) power-up delay - holds microprocessor in reset long enough for clock stabilization and peripheral readiness. |
| Supply Current | 17 μA (typical) at VCC < 3.6 V - enables use in battery-powered or ultra-low-power embedded systems without significant quiescent load. |
| VCC Operating Range | 1.0 V to 5.5 V - supports operation during brownout conditions and allows valid reset signaling even as supply collapses. |
| RESET Output Type | Active-high push-pull - drives logic-high directly without external components, compatible with standard CMOS inputs requiring asserted high for reset release. |
| Temperature Range | −40°C to +125°C - qualified for automotive under-hood, industrial control, and harsh-environment applications. |
| Package | 3-lead SOT-23 (RT-3) - surface-mount footprint with JEDEC-compliant dimensions (2.90 mm × 1.30 mm) for high-density PCB assembly. |
Pinout & Package
ADM810MARTZ-REEL uses a 3-lead SOT-23 (RT-3) package per JEDEC TO-236-AB standard, with 1.90 mm height, 2.90 mm length, and 1.30 mm width. Pin 1 is GND, Pin 2 is RESET (active-high output), and Pin 3 is VCC (monitored supply input).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Ground reference | 0 V return path for internal comparator and output driver; must be connected to system ground plane for noise immunity and accurate threshold sensing. |
| RESET (Pin 2) | Active-high push-pull output | Drives logic-high when VCC ≥ 4.38 V and timeout expires; sinks current during reset assertion; no external pull-up required. |
| VCC (Pin 3) | Monitored supply input | Primary power rail being supervised; also powers internal circuitry; functional down to 1.0 V for brownout detection. |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune comparator | Rejects transients ≤100 mV overdrive for ≥400 μs - prevents false resets during switching noise or ESD events on VCC. |
| Low-voltage reset operation | Valid RESET signal generation down to VCC = 1.0 V - ensures deterministic reset behavior during deep brownouts before complete power loss. |
| Precision threshold tolerance | ±1.6% over −40°C to +85°C (4.31 V to 4.45 V) - eliminates need for external trimming in 4.4 V supply monitoring applications. |
| Ultra-low quiescent current | 17 μA typical at VCC < 3.6 V - extends battery life in portable instrumentation and remote sensors without compromising supervision reliability. |
| Wide temperature qualification | −40°C to +125°C operation - meets AEC-Q100 stress requirements for automotive engine control units and industrial PLC modules. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM809MARTZ-REEL | Same 4.38 V threshold and SOT-23 package, but active-low push-pull RESET output. | Requires inverted reset logic handling in MCU firmware or external inverter; incompatible with MCUs expecting active-high reset. | Select only if target MCU accepts active-low reset and board layout cannot accommodate signal inversion. |
| MAX809TRD3T | 4.38 V threshold, active-high reset, but 140 ms min timeout (vs. 240 ms typ for ADM810MARTZ-REEL); 20 μA supply current. | Shorter guaranteed reset duration may not satisfy FPGA or DSP boot timing requirements; higher current impacts battery life. | Acceptable for simpler 8-bit MCUs with shorter initialization, but verify timing margin against specific processor datasheet. |
Compared with ADM809MARTZ-REEL, ADM810MARTZ-REEL avoids external inversion logic; compared with MAX809TRD3T, it provides longer guaranteed reset hold time and lower quiescent current-critical for safety-critical and battery-operated designs.

FAQ
What is the reset polarity and output structure of ADM810MARTZ-REEL?
The ADM810MARTZ-REEL features an active-high push-pull RESET output (Pin 2). Unlike open-drain variants, it actively drives both logic high and low states without requiring external pull-up resistors. This simplifies interface design with MCUs that require asserted-high reset signals, such as many ARM Cortex-M and Renesas RX series devices. The output sinks 1.2 mA at VCC = VTH(min) and sources 150 μA under specified conditions.
Does ADM810MARTZ-REEL support operation below 2.0 V VCC?
Yes, ADM810MARTZ-REEL remains fully functional down to 1.0 V VCC, maintaining accurate reset assertion during brownout conditions. Its internal circuitry continues to monitor the supply and assert RESET until VCC rises above the 4.38 V threshold and the 240 ms timeout expires. This capability is confirmed in the Absolute Maximum Ratings table and General Description section of the Rev. I datasheet.
What is the guaranteed reset timeout duration for ADM810MARTZ-REEL across temperature?
The ADM810MARTZ-REEL guarantees a minimum reset timeout of 140 ms and maximum of 460 ms over −40°C to +85°C, with 240 ms typical. At elevated temperatures (85°C to 125°C), the range widens to 100 ms minimum and 840 ms maximum. These values are specified in Table 1 under "RESET ACTIVE TIMEOUT PERIOD" and reflect the internal RC timer's process and temperature variation.
How does ADM810MARTZ-REEL handle fast transients on the VCC line?
ADM810MARTZ-REEL incorporates a glitch-immune reset comparator that rejects transients ≤100 mV overdrive for durations up to 400 μs, as shown in Figure 11 of the datasheet. This prevents spurious resets caused by switching noise, ESD, or load-dump events on the monitored supply rail-critical for reliability in automotive and industrial environments.
Is ADM810MARTZ-REEL RoHS compliant and what does the 'Z' suffix indicate?
Yes, ADM810MARTZ-REEL is RoHS compliant, as indicated by the 'Z' suffix in the part number per the Ordering Guide footnote. The device uses lead-free terminations and complies with EU Directive 2011/65/EU. RoHS compliance is verified through material declarations and manufacturing process controls documented by Analog Devices, and the part is marked with date code 'XX' on the bottom per specification.
