Product details
Overview
ADM810JAKSZ-REEL7 from Analog Devices is a microprocessor supervisory circuit in 3-lead SC70 package, providing active-high push-pull reset output with 4.00 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 ADM810JAKSZ-REEL7 datasheet, ADM810JAKSZ-REEL7 pinout, ADM810JAKSZ-REEL7 application, or ADM810JAKSZ-REEL7 equivalent, key selection criteria include reset polarity (active-high), SC70 packaging, −40°C to +125°C temperature range, and compatibility with 4.0 V nominal supply rails in space-constrained designs.
Technical Context
The ADM810JAKSZ-REEL7 integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms reset timer. Its reset assertion remains valid even as VCC drops to 1.0 V, enabling robust brownout detection.
Unlike open-drain variants (e.g., ADM803), this device uses a push-pull output stage capable of sourcing/sinking current without external components-supporting direct interface to CMOS inputs across 1.8–5.5 V logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.00 V (typical at 25°C); monitors 4.0 V supply rails with ±100 mV tolerance over −40°C to +85°C. |
| Reset Timeout | 240 ms (typical); holds microprocessor in reset until supply stabilizes after power-up. | VCC Operating Range | 1.0 V to 5.5 V; enables operation during deep brownout and supports wide-input systems. |
| Supply Current | 17 μA (typical at VCC < 3.6 V); ultra-low quiescent draw for battery-backed or energy-sensitive applications. |
| Output Type | Active-high push-pull; eliminates need for external pull-up resistor and drives CMOS/TTL loads directly. |
| Temperature Range | −40°C to +125°C; qualified for automotive under-hood, industrial control, and harsh-environment deployment. |
| Package | 3-lead SC70 (KS-3); 2.0 mm × 2.1 mm footprint ideal for compact PCB layouts. |
Pinout & Package
ADM810JAKSZ-REEL7 uses a 3-lead SC70 package (JEDEC KS-3) with 0.65 mm lead pitch and coplanarity ≤0.10 mm. Pin 1 = GND, Pin 2 = RESET (active-high output), Pin 3 = VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for internal comparator and output stage; must be low-impedance connection to system ground plane. |
| 2 | RESET | Active-high push-pull output; asserts high when VCC < 4.00 V and remains high for 240 ms after VCC exceeds threshold. |
| 3 | VCC | Monitored supply input; powers internal circuitry and defines operating voltage range (1.0–5.5 V). |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune comparator | Rejects transients up to 100 mV overdrive for ≤400 µs-prevents false resets during supply noise. |
| Low-VCC reset operation | Maintains valid RESET signal down to 1.0 V VCC-ensures deterministic behavior during deep undervoltage events. |
| Precision threshold accuracy | ±70 mV over −40°C to +85°C (4.00 V nominal)-enables tight margining on 4.0 V rails without derating. |
| Ultra-low power consumption | 17 μA typical supply current-extends battery life in portable instrumentation and remote sensors. |
| Wide temperature qualification | Specified from −40°C to +125°C-supports deployment in automotive engine control units and industrial PLCs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809SEUR+T | 4.00 V threshold, SOT-23-3 package, active-low reset, 140 ms min timeout. | Requires level-shifting or inverter for active-high MCU reset input; larger footprint than SC70. | Select when board layout already uses SOT-23 and system design accommodates active-low reset signaling. |
| TPS3808G33DBVR | 3.3 V threshold, SOT-23-6 package, adjustable delay, 1.8–6.0 V VCC range. | Not a drop-in replacement due to different threshold and 6-pin configuration; requires PCB redesign. | Choose only if 3.3 V rail monitoring is required and programmable delay adds value over fixed 240 ms timeout. |
Compared with MAX809SEUR+T and TPS3808G33DBVR, the ADM810JAKSZ-REEL7 offers exact 4.0 V threshold matching, smallest SC70 footprint, and native active-high push-pull output-reducing BOM count and simplifying layout in 4.0 V microcontroller systems.

FAQ
What is the reset polarity and output structure of ADM810JAKSZ-REEL7?
The ADM810JAKSZ-REEL7 provides an active-high push-pull RESET output. Unlike open-drain variants (e.g., ADM803), it does not require an external pull-up resistor. Pin 2 asserts high when VCC falls below 4.00 V and remains high for 240 ms after VCC rises above threshold-directly compatible with most modern microcontrollers' active-high reset inputs.
Does ADM810JAKSZ-REEL7 support operation below 1.8 V VCC?
Yes, ADM810JAKSZ-REEL7 is fully specified down to 1.0 V VCC. Its internal comparator and reset generator remain functional at this level, ensuring deterministic reset assertion during deep brownout conditions-critical for fail-safe behavior in battery-powered or capacitor-held systems.
What is the temperature range qualification for ADM810JAKSZ-REEL7?
ADM810JAKSZ-REEL7 is rated for −40°C to +125°C operation, with all electrical specifications guaranteed across this full industrial/automotive extended range. This includes reset threshold accuracy, timeout duration, and supply current-making it suitable for under-hood, factory floor, and outdoor-deployed equipment.
How does the ADM810JAKSZ-REEL7 differ from ADM809JAKSZ-REEL7?
The ADM810JAKSZ-REEL7 and ADM809JAKSZ-REEL7 share identical 4.00 V threshold, SC70 package, and −40°C to +125°C rating-but differ in reset polarity: ADM810JAKSZ-REEL7 outputs active-high RESET, while ADM809JAKSZ-REEL7 outputs active-low. Both use push-pull outputs; neither requires external pull-up resistors.
Is ADM810JAKSZ-REEL7 RoHS compliant and what does the 'Z' suffix indicate?
Yes, ADM810JAKSZ-REEL7 is RoHS compliant-the 'Z' in the part number explicitly denotes compliance with EU Directive 2011/65/EU. The device contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and is marked with bottom-side date code per Analog Devices' RoHS implementation guidelines.
