Product details
Overview
ADM810LAKSZ-REEL 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 17 μA typical supply current, and is qualified for −40°C to +125°C industrial/automotive environments. It monitors 5 V supply rails in embedded controllers and intelligent instruments.
For engineers reviewing the ADM810LAKSZ-REEL datasheet, ADM810LAKSZ-REEL pinout, ADM810LAKSZ-REEL application, or ADM810LAKSZ-REEL equivalent, key selection criteria include reset polarity (active-high), SC70-3 package compatibility, guaranteed reset assertion below 1 V VCC, and temperature-stable 4.63 V threshold across full automotive grade range.
Technical Context
The ADM810LAKSZ-REEL integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms reset timer. Its reference circuit maintains ±0.07 V accuracy over −40°C to +125°C, enabling reliable brownout detection even during fast transients.
Unlike open-drain variants, this device features a push-pull RESET output capable of sourcing 150 μA at 1.8 V < VCC < VTH(min), eliminating external pull-up components. It asserts RESET high while VCC remains below 4.63 V and holds it high for 240 ms after VCC exceeds threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.63 V (±0.07 V over −40°C to +125°C); precisely monitors 5 V supply rails without external calibration. |
| Reset Polarity | Active-high push-pull output; directly interfaces CMOS inputs without pull-up resistor or level-shifting. |
| Reset Timeout | 240 ms typical power-on delay; ensures microprocessor stabilization before release from reset state. |
| Supply Current | 17 μA typical at VCC < 3.6 V; enables use in battery-backed or ultra-low-power embedded systems. |
| VCC Operating Range | 1.0 V to 5.5 V; guarantees functional reset assertion even during deep brownout conditions. |
| Package | 3-lead SC70 (KS-3); 2.0 mm × 2.1 mm footprint with 0.65 mm pitch, suitable for space-constrained PCBs. |
| Temperature Range | −40°C to +125°C; qualified for under-hood automotive, industrial control, and harsh-environment applications. |
Pinout & Package
ADM810LAKSZ-REEL uses a 3-lead SC70 (KS-3) package with exposed pad not electrically connected. Pin 1 = VCC, Pin 2 = RESET (active-high push-pull), Pin 3 = GND - confirmed per Figure 4 and Table 4 of Rev. I datasheet.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC) | Supply Input | Monitored voltage rail input; device operates and asserts RESET when VCC drops below 4.63 V. |
| 2 (RESET) | Active-High Output | Push-pull logic output; drives high during reset condition (VCC < 4.63 V) and for 240 ms after recovery. |
| 3 (GND) | Ground Reference | 0 V reference for internal comparator and output stage; must be low-impedance connection to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune comparator | Rejects transients ≤100 µs duration at VTH – VCC ≥ 100 mV; prevents false resets during EMI or switching noise. |
| Low-VCC reset operation | Functional down to 1.0 V VCC; ensures deterministic reset behavior during deep undervoltage events. |
| Precision threshold tolerance | ±0.07 V at 25°C, ±0.19 V over −40°C to +125°C; eliminates need for external trimming in 5 V systems. |
| Automotive-grade qualification | Specified and tested across −40°C to +125°C; meets AEC-Q100 stress requirements for reliability-critical applications. |
| No external components required | Push-pull output and internal timing eliminate pull-up resistors, capacitors, or external RC networks. |

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 | 4.63 V threshold, SOT-23-3 package, 1.2 V min VCC, but only rated to +85°C (not +125°C). | Limited to commercial/industrial temperature range; unsuitable for under-hood automotive use. | Select when cost sensitivity outweighs extended temperature requirement and SOT-23 footprint is preferred. |
| TPS3808G33DBVR | 3.3 V threshold (not 4.63 V), adjustable via external resistor, 1.8 V min VCC, −40°C to +125°C rated. | Requires external resistor network for 4.63 V setting; adds BOM count and layout area vs. fixed-threshold ADM810LAKSZ-REEL. | Choose only if system requires reconfigurable threshold or dual-voltage monitoring capability. |
Compared with MAX809SEUR+T and TPS3808G33DBVR, the ADM810LAKSZ-REEL delivers guaranteed automotive-grade operation, fixed-pin 4.63 V accuracy without external components, and SC70 footprint - making it optimal for space-constrained, high-reliability 5 V microcontroller supervision where temperature robustness and simplicity are critical.

FAQ
What is the reset polarity and output type of the ADM810LAKSZ-REEL?
The ADM810LAKSZ-REEL features an active-high push-pull RESET output. Unlike open-drain variants (e.g., ADM803), it does not require an external pull-up resistor. RESET goes high when VCC falls below 4.63 V and remains high for 240 ms after VCC rises above threshold, directly driving CMOS-compatible inputs.
Does the ADM810LAKSZ-REEL support operation below 2.0 V VCC?
Yes, the ADM810LAKSZ-REEL is fully functional down to 1.0 V VCC. Its internal circuitry continues to monitor voltage and assert RESET correctly even during severe brownout conditions, a key differentiator from many competing supervisors that cease operation below 1.8 V.
What is the guaranteed reset timeout period across temperature for ADM810LAKSZ-REEL?
The ADM810LAKSZ-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 +85°C to +125°C, the range widens to 100–840 ms. This ensures robust reset hold time across full automotive grade without external timing components.
Is the ADM810LAKSZ-REEL RoHS compliant and what does the 'Z' suffix indicate?
Yes, the 'Z' in ADM810LAKSZ-REEL denotes RoHS compliance per 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 date code 'XX' on the bottom per ordering guide footnote 3.
How does the ADM810LAKSZ-REEL handle fast transients on the VCC line?
The ADM810LAKSZ-REEL incorporates a glitch-immune comparator design. As shown in Figure 11 of the datasheet, it rejects transients up to 100 µs in duration when the overdrive (VTH – VCC) exceeds 100 mV - preventing spurious resets during switching noise or ESD events without requiring external filtering.
