Product details
Overview
ADM810RAKSZ-REEL from Analog Devices is a microprocessor supervisory circuit with active-high push-pull RESET output, 2.63 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. It monitors 3 V supply rails in embedded controllers and intelligent instruments.
For engineers reviewing the ADM810RAKSZ-REEL datasheet, ADM810RAKSZ-REEL pinout, ADM810RAKSZ-REEL application, or ADM810RAKSZ-REEL equivalent, key selection criteria include reset polarity (active-high), SC70-3 package compatibility, guaranteed 140–460 ms reset timeout over temperature, and support for brownout detection below 1.2 V VCC.
Technical Context
The ADM810RAKSZ-REEL integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms timer. Its reset assertion remains valid even as VCC drops to 1.0 V, enabling reliable brownout detection before system collapse.
It uses a bandgap-referenced threshold of 2.63 V (±3.5% over −40°C to +125°C) and features push-pull output capable of sourcing 150 μA at 1.8 V < VCC < VTH(min), eliminating need for external pull-up resistors unlike open-drain variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.63 V ±3.5% over −40°C to +125°C - ensures accurate 3 V rail monitoring despite temperature drift. |
| Reset Timeout (min) | 140 ms - guarantees sufficient hold time for microprocessor initialization during power-up. |
| Supply Current | 17 μA at VCC < 3.6 V - enables integration into battery-powered portable systems without significant quiescent load. |
| VCC Operating Range | 1.0 V to 5.5 V - supports operation during deep brownout and allows use across 1.8 V to 5 V logic families. |
| Output Type | Active-high push-pull - drives RESET high without external components, simplifying PCB layout and reducing BOM count. |
| Reset Assertion Voltage | Valid down to 1.0 V VCC - maintains deterministic reset state until supply collapses completely. |
| Temp Range | −40°C to +125°C - qualified for under-hood automotive and industrial control applications. |
Pinout & Package
ADM810RAKSZ-REEL is housed in a 3-lead SC70 (KS-3) package, measuring 2.00 mm × 1.25 mm × 0.95 mm, with gull-wing leads and JEDEC-compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND | Ground reference for internal comparator and output driver; must be low-impedance connection to system ground plane. |
| 2 | RESET | Active-high push-pull output; asserts high when VCC < 2.63 V and holds high for 240 ms after VCC rises above threshold. |
| 3 | VCC | Monitored supply input; powers internal circuitry and defines operating voltage range (1.0 V to 5.5 V). |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune reset comparator | Rejects transients up to 100 mV overdrive for ≤200 μs - prevents false resets from supply noise or ESD coupling. |
| Precision threshold tolerance | ±3.5% over full temperature range - eliminates need for external trimming in 3 V system designs. |
| Low-voltage reset assertion | Operates down to 1.0 V VCC - ensures reset remains asserted through final stages of power collapse. |
| Push-pull output architecture | No external pull-up required - reduces component count and improves rise/fall time consistency vs. open-drain alternatives. |
| Ultra-low quiescent current | 17 μA typical at 3.3 V - extends battery life in always-on monitoring circuits without sacrificing reliability. |
Applications
| Industrial PLC Controllers | Automotive Body Control Modules |
|---|---|

IC Role / Device Role / Timing Role: Supervisory circuit asserting active-high RESET to hold MCU in known state during cold cranking or load dump events. Use Value: 2.63 V threshold matches nominal 3 V rail; 140–460 ms timeout accommodates slow-ramping industrial power supplies; −40°C to +125°C rating ensures field reliability. |
Use Scenario: Embedded in body control unit (BCU) to supervise 3 V domain powering door lock MCU and CAN transceiver interface. IC Role / Device Role / Timing Role: Generates clean, glitch-free active-high reset pulse synchronized to 3 V rail recovery after ignition cycling. Use Value: Push-pull output interfaces directly to 3 V logic inputs; 1.0 V VCC operation prevents premature deassertion during battery sag; SC70 package saves space on dense automotive PCBs. |
| Medical Infusion Pumps | Smart Energy Meters |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809RTRG+T | 2.63 V threshold, SOT-23-3 package, 140 ms min timeout, but only rated to +85°C (vs. +125°C). | Limited to commercial/industrial ambient; unsuitable for under-hood automotive or high-temp industrial enclosures. | Select when ambient stays below 85°C and SOT-23 footprint is preferred. |
| TPS3808G12DBVR | 1.2 V adjustable threshold via external resistor divider; 200 ms fixed timeout; 2.5 μA quiescent current. | Requires external components for 2.63 V setting; lower current but lacks guaranteed 1.0 V operation. | Select when ultra-low power dominates and precise 2.63 V is implemented externally. |
Compared with MAX809RTRG+T and TPS3808G12DBVR, ADM810RAKSZ-REEL uniquely combines automotive-grade temperature range, SC70 footprint, push-pull active-high output, and guaranteed 1.0 V operation - making it optimal for space-constrained, high-reliability 3 V systems where reset timing and voltage accuracy are non-negotiable.

FAQ
What is the reset polarity and output structure of the ADM810RAKSZ-REEL?
The ADM810RAKSZ-REEL features an active-high push-pull RESET output. Unlike open-drain variants such as the ADM803, it does not require an external pull-up resistor. The RESET pin drives high when VCC falls below 2.63 V and remains high for 240 ms (typical) after VCC rises above threshold - ensuring clean, robust reset signaling in 3 V systems.
Does the ADM810RAKSZ-REEL operate reliably at low supply voltages?
Yes. The ADM810RAKSZ-REEL guarantees functional reset assertion down to 1.0 V VCC across its full −40°C to +125°C temperature range. This capability ensures the reset signal remains valid during severe brownout conditions, preventing microprocessor malfunction before complete power loss - a critical feature confirmed in Table 1 and General Description sections of the datasheet.
What package type and dimensions does the ADM810RAKSZ-REEL use?
The ADM810RAKSZ-REEL is packaged in a 3-lead SC70 (JEDEC KS-3) case measuring 2.00 mm × 1.25 mm × 0.95 mm. Its gull-wing lead configuration and 0.65 mm pitch comply with standard reflow profiles. Pin 1 is GND, Pin 2 is RESET (active-high), and Pin 3 is VCC - as verified in Figure 4 and Table 4 of the official Analog Devices datasheet Rev. I.
How does the ADM810RAKSZ-REEL handle supply transients and noise?
The ADM810RAKSZ-REEL incorporates a glitch-immune reset comparator that rejects fast transients up to 100 mV overdrive for durations ≤200 μs, as shown in Figure 11. This design prevents false resets caused by switching noise, ESD coupling, or load dump spikes - a key differentiator versus basic voltage detectors lacking transient immunity.
Is the ADM810RAKSZ-REEL RoHS compliant and what is its temperature qualification?
Yes. The "Z" suffix in ADM810RAKSZ-REEL denotes RoHS compliance per EU Directive 2011/65/EU. It is fully qualified for operation from −40°C to +125°C, with all specifications - including reset threshold (2.63 V ±3.5%), timeout (140–460 ms), and supply current (17 μA) - guaranteed across this extended range, as documented in Tables 1 and 3 of the datasheet.
