Product details
Overview
ADM810TAKSZ-REEL from Analog Devices is a microprocessor supervisory circuit with active-high push-pull RESET output, 3.08 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 3.3 V supply rails in embedded controllers and intelligent instruments.
For engineers reviewing the ADM810TAKSZ-REEL datasheet, ADM810TAKSZ-REEL pinout, ADM810TAKSZ-REEL application, or ADM810TAKSZ-REEL equivalent, key selection criteria include reset polarity (active-high), SC70-3 package compatibility, guaranteed operation at VCC ≥ 1.0 V, and temperature-stable threshold (±0.15 V over −40°C to +125°C).
Technical Context
The ADM810TAKSZ-REEL integrates a precision voltage comparator with built-in glitch immunity and an internal 240 ms reset timer. Its reference circuit maintains ±0.15 V accuracy across −40°C to +125°C, enabling reliable brownout detection even during fast transients on VCC.
It features a push-pull RESET output capable of sourcing 150 μA at 1.8 V < VCC < VTH(min), with logic-high voltage ≥ 0.8 × VCC and logic-low voltage ≤ 0.4 V at VTH(min) under 3.2 mA sink load - ensuring direct interface with CMOS inputs without external pull-ups.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.08 V (typical), ±0.15 V over full temperature range - ensures accurate 3.3 V rail monitoring with margin against undervoltage faults |
| Reset Timeout | 240 ms (typical), 140–460 ms (min–max) - holds microprocessor in reset until power stabilizes post-power-up | Supply Current | 17 μA (typical at VCC < 3.6 V, −40°C to +85°C) - enables use in battery-powered portable systems |
| VCC Operating Range | 1.0 V to 5.5 V - supports valid reset assertion during deep brownout down to 1 V |
| Output Type | Active-high push-pull - eliminates need for external pull-up resistor; directly drives CMOS/TTL inputs |
| Package | 3-lead SC70 (KS-3) - 2.0 mm × 1.25 mm footprint, compatible with high-density PCB layouts |
| Temperature Range | −40°C to +125°C - qualified for automotive under-hood and industrial control applications |
Pinout & Package
ADM810TAKSZ-REEL uses a 3-lead SC70 (KS-3) package: 1.25 mm × 2.00 mm body, 0.65 mm lead pitch, coplanarity ≤ 0.10 mm. Pin 1 = VCC, Pin 2 = RESET (active-high push-pull), Pin 3 = GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VCC | Monitored supply input; device operates and asserts reset when VCC drops below 3.08 V |
| 2 | RESET | Active-high push-pull output; remains high during VCC fault and for 240 ms after recovery - no external components required |
| 3 | GND | Ground reference for internal comparator and output driver; 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 from EMI or switching noise |
| Low-voltage operation | Valid RESET assertion down to VCC = 1.0 V - ensures fail-safe behavior during severe brownout conditions |
| Precision threshold | 3.08 V ±0.15 V over −40°C to +125°C - eliminates need for external trimming in 3.3 V systems |
| Ultra-low quiescent current | 17 μA typical - extends battery life in always-on monitoring applications such as telematics or sensor nodes |
| RoHS-compliant packaging | SC70-3 with Z-suffix (lead-free, halogen-free) - meets automotive and industrial environmental compliance requirements |
Applications
| Industrial PLC Controllers | Automotive Body Control Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TTRG+T | 3.08 V threshold, SOT-23-3 package, 1.2 μA max supply current, active-low open-drain output | Requires external pull-up resistor; lower quiescent current but incompatible reset polarity and drive architecture | Select only if active-low reset and ultra-low power (<2 μA) are mandatory and board layout allows pull-up addition |
| TPS3808G30DBVR | 3.0 V threshold (±0.5%), SOT-23-6 package, 16 μA typical supply current, active-high push-pull output | Larger footprint (6-pin vs. 3-pin); tighter threshold tolerance but different pinout and higher cost per unit | Choose when tighter threshold accuracy (±15 mV) is required and PCB space permits 6-pin package |
Compared with MAX809TTRG+T and TPS3808G30DBVR, the ADM810TAKSZ-REEL uniquely combines active-high push-pull drive, SC70-3 footprint, and guaranteed 3.08 V threshold stability over −40°C to +125°C - making it optimal for space-constrained, high-reliability 3.3 V systems requiring zero-external-component reset generation.

FAQ
What is the reset polarity and output structure of the ADM810TAKSZ-REEL?
The ADM810TAKSZ-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. The output drives logic-high (≥0.8 × VCC) when asserted and logic-low (≤0.4 V at 3.2 mA sink) when deasserted - enabling direct interface with standard CMOS inputs. This behavior is confirmed in the Functional Block Diagram and Pin Function Descriptions of the ADM803/ADM809/ADM810 datasheet Rev. I.
What is the exact reset threshold voltage for ADM810TAKSZ-REEL and how does it vary with temperature?
The ADM810TAKSZ-REEL has a nominal reset threshold of 3.08 V at 25°C, with guaranteed limits of 3.00 V to 3.15 V over −40°C to +85°C and 2.95 V to 3.21 V over −40°C to +125°C. This 3.08 V option corresponds to the "T" grade in Table 3 of the datasheet and is optimized for monitoring 3.3 V supplies with adequate margin. The temperature coefficient is specified at 30 ppm/°C maximum.
Does ADM810TAKSZ-REEL support operation below 2.0 V VCC, and what happens to the RESET output at low voltage?
Yes, the ADM810TAKSZ-REEL operates down to VCC = 1.0 V and continues to assert RESET (logic-high) as long as VCC remains below the 3.08 V threshold. The datasheet specifies valid RESET output voltage levels down to VCC = 1.0 V, with logic-low voltage ≤ 0.4 V at 3.2 mA sink load. Below 1.0 V, functionality is not guaranteed - consistent with Absolute Maximum Ratings limiting VCC to −0.3 V to +6 V.
What package type and dimensions does ADM810TAKSZ-REEL use, and is it RoHS-compliant?
The ADM810TAKSZ-REEL uses the 3-lead SC70 (KS-3) package: 2.00 mm × 1.25 mm body size, 0.65 mm lead pitch, and maximum height of 0.95 mm. The "Z" suffix in the part number explicitly denotes RoHS compliance (lead-free, halogen-free). Outline dimensions are documented in Figure 15 of the datasheet Rev. I, and JEDEC SC70 compliance is confirmed in the package description.
How does the ADM810TAKSZ-REEL handle fast transients on the VCC line, and what protection is built in?
ADM810TAKSZ-REEL incorporates a glitch-immune reset comparator that rejects transients ≤ 100 µs duration when the overdrive (VTH – VCC) is ≥ 100 mV. As shown in Figure 11 of the datasheet, this immunity increases for larger overdrive voltages - e.g., up to ~350 µs rejection at 200 mV overdrive. This prevents false resets caused by switching noise, ESD coupling, or load-step events common in motor-driven or RF-intensive systems.
