Product details
Overview
ADM810JAKS-REEL7 from Analog Devices is a microprocessor supervisory circuit with push-pull active-high RESET output, 4.00 V reset threshold (±2.5% over −40°C to +125°C), 240 ms typical power-on reset timeout, 17 μA supply current at VCC < 3.6 V, and operation down to 1.0 V VCC. It monitors supply voltage in embedded microcontroller systems requiring reliable brownout detection and deterministic reset assertion.
For engineers reviewing the ADM810JAKS-REEL7 datasheet, ADM810JAKS-REEL7 pinout, ADM810JAKS-REEL7 application, or ADM810JAKS-REEL7 equivalent, key selection criteria include active-high push-pull drive capability, SC70-3 package compatibility, −40°C to +125°C industrial temperature range, precise 4.00 V threshold tolerance, and guaranteed reset assertion below 1 V VCC.
Technical Context
The ADM810JAKS-REEL7 integrates a precision bandgap voltage reference and comparator with built-in glitch immunity to reject fast transients on VCC up to 100 V/μs. Its internal timer ensures reset remains asserted for 240 ms (typical) after VCC rises above the 4.00 V threshold, holding the microprocessor in reset until supply stabilization.
Unlike open-drain variants (e.g., ADM803), the ADM810JAKS-REEL7 features a push-pull output capable of sourcing 150 μA at 1.8 V < VCC < VTH(min) and sinking 3.2 mA at VCC = VTH(min), eliminating need for external pull-up resistors. It operates across full VCC range of 1.0 V to 5.5 V with supply current as low as 17 μA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.00 V ±2.5% over −40°C to +125°C - precisely monitors 4.0 V rails without external components |
| Reset Output Type | Active-high push-pull - drives high/low directly; no external pull-up required |
| Power-On Reset Timeout | 240 ms typical - ensures microprocessor remains held in reset long enough for stable clock and supply settling |
| Supply Current | 17 μA at VCC < 3.6 V, −40°C to +85°C - enables use in battery-powered or ultra-low-power systems |
| VCC Operating Range | 1.0 V to 5.5 V - asserts reset even during deep brownout conditions down to 1 V |
| Temperature Range | −40°C to +125°C - qualified for automotive under-hood and industrial control environments |
| Package | 3-lead SC70 (KS-3) - 2.0 mm × 1.25 mm footprint, compatible with high-density PCB layouts |
Pinout & Package
ADM810JAKS-REEL7 is housed in a 3-lead SC70 (KS-3) package with 0.65 mm pitch, 2.0 mm × 1.25 mm body size, and 0.10 mm max coplanarity per JEDEC SC70 standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: VCC | Supply Input | Monitored voltage rail input; device operates and asserts reset based on this node |
| 2: RESET | Active-High Push-Pull Output | Drives logic-high when VCC ≥ 4.00 V (after timeout); drives logic-low when VCC < 4.00 V or during reset period |
| 3: GND | Ground Reference | 0 V reference for all internal circuitry and output stage; must be low-impedance connection |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune reset comparator | Rejects transients ≤100 V/μs on VCC - prevents false resets from switching noise or ESD |
| Precision 4.00 V threshold | ±2.5% tolerance over full temperature range - eliminates need for external trimming or calibration |
| Low-voltage reset assertion | Operates and asserts reset down to VCC = 1.0 V - ensures fail-safe behavior during severe brownouts |
| Push-pull active-high output | Sources 150 μA / sinks 3.2 mA - interfaces directly with CMOS inputs without pull-up resistor |
| Ultra-low quiescent current | 17 μA at 3.3 V and −40°C to +85°C - extends battery life in portable instrumentation |
Applications
| Industrial PLC Controller | Automotive Body Control Module |
|---|---|

Use Scenario: Monitors 4.0 V auxiliary supply powering MCU and CAN transceiver in programmable logic controller cabinets exposed to wide ambient temperatures. IC Role / Device Role / Timing Role: Supervisory circuit asserting active-high reset to hold ARM Cortex-M4 in known state during cold start and line sag events. Use Value: 240 ms fixed timeout guarantees firmware initialization completes before peripheral clocks stabilize; 1.0 V minimum VCC operation prevents lockup during 12 V battery dip to 9 V. |

IC Role / Device Role / Timing Role: Voltage monitor generating clean, glitch-immune reset signal synchronized to 4.0 V rail integrity. Use Value: Built-in transient rejection (≤100 V/μs) avoids spurious resets during alternator switching; −40°C to +125°C rating covers under-dash thermal extremes. |
| Medical Infusion Pump | Smart Energy Meter |
|
Use Scenario: Ensures safe startup and fault recovery of safety-critical MCU controlling motor actuation and pressure sensing in battery-backed infusion devices. IC Role / Device Role / Timing Role: Fail-safe reset generator that asserts on power-up, brownout, and power-down - critical for IEC 62304 Class C compliance. Use Value: Active-high push-pull output simplifies interface to MCU's dedicated reset pin; 4.00 V threshold matches regulated 4.0 V LDO output feeding main processor. |
Use Scenario: Supervises 4.0 V rail powering metrology SoC and RTC in utility-grade electricity meters deployed outdoors with wide seasonal temperature swings. IC Role / Device Role / Timing Role: Precision voltage supervisor providing deterministic reset timing independent of MCU internal reset circuitry. Use Value: 2.5% threshold accuracy over −40°C to +125°C eliminates recalibration; SC70 package enables compact two-layer PCB design. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM809JAKSZ-REEL7 | Same 4.00 V threshold and SC70 package, but active-low push-pull RESET output | Requires MCU reset pin configured for active-low assertion; incompatible with active-high-only reset inputs | Select only if target system design expects active-low reset polarity |
| TPS3808G33DBVR | 3.3 V threshold, 200 ms reset timeout, 1.8–6.0 V VCC range, SOT-23-3 package | Not a direct replacement due to different threshold voltage and shorter timeout; requires board-level redesign for 4.0 V monitoring | Consider only if redesigning for 3.3 V rail supervision and accepting 200 ms timeout |
Compared with ADM809JAKSZ-REEL7, ADM810JAKS-REEL7 provides active-high reset polarity essential for MCUs lacking active-low reset support; compared with TPS3808G33DBVR, it delivers exact 4.00 V threshold and longer 240 ms timeout required for slower-starting power supplies in industrial systems.

FAQ
What is the reset output polarity of ADM810JAKS-REEL7?
The ADM810JAKS-REEL7 features an active-high push-pull RESET output. When VCC falls below the 4.00 V threshold, RESET goes low and remains low for 240 ms (typical) after VCC rises back above threshold. This differs from ADM803 (open-drain active-low) and ADM809 (push-pull active-low). The ADM810JAKS-REEL7 does not require an external pull-up resistor due to its integrated output driver.
Does ADM810JAKS-REEL7 support operation below 2.0 V VCC?
Yes, ADM810JAKS-REEL7 is fully specified to operate and assert reset down to VCC = 1.0 V. Its internal circuitry remains functional and the RESET output correctly transitions even during deep brownout conditions where VCC drops below 2.0 V - a critical capability for fail-safe behavior in systems with unregulated or weakly regulated supplies.
What is the temperature range qualification for ADM810JAKS-REEL7?
ADM810JAKS-REEL7 is rated for operation from −40°C to +125°C, with all electrical specifications-including 4.00 V reset threshold (±2.5%), 240 ms reset timeout, and 17 μA supply current-guaranteed across this full industrial temperature range. This makes ADM810JAKS-REEL7 suitable for under-hood automotive, factory automation, and outdoor metering applications.
Can ADM810JAKS-REEL7 replace ADM809JAKSZ-REEL7 on the same PCB?
No, ADM810JAKS-REEL7 cannot serve as a drop-in replacement for ADM809JAKSZ-REEL7 because they differ in reset output polarity: ADM810JAKS-REEL7 outputs active-high RESET, while ADM809JAKSZ-REEL7 outputs active-low RESET. Swapping them would invert reset logic and likely prevent proper system boot. Board-level redesign is required to accommodate the polarity change.
What package type is used by ADM810JAKS-REEL7?
ADM810JAKS-REEL7 uses a 3-lead SC70 package (JEDEC KS-3), measuring 2.0 mm × 1.25 mm with 0.65 mm lead pitch. This compact, surface-mount package supports high-density PCB layouts and is distinct from the SOT-23 variant (ADM810JARTZ-REEL7), which shares identical electrical specs but has different mechanical dimensions and thermal characteristics.
