Product details
Overview
ADM810RARTZ-REEL7 from Analog Devices is a microprocessor supervisory circuit with push-pull active-high RESET output, 2.63 V reset threshold, −40°C to +125°C operating temperature range, and 17 μA supply current. It monitors VCC down to 1 V, asserts reset for 240 ms (typical) on power-up, and is used in embedded controllers requiring reliable brownout detection.
For engineers reviewing the ADM810RARTZ-REEL7 datasheet, ADM810RARTZ-REEL7 pinout, ADM810RARTZ-REEL7 application, or ADM810RARTZ-REEL7 equivalent, key selection criteria include reset polarity (active-high), SOT-23-3 package compatibility, guaranteed operation at 1 V VCC, temperature-stable 2.63 V threshold, and low-power supervision for industrial microcontroller systems.
Technical Context
The ADM810RARTZ-REEL7 implements a precision voltage comparator with built-in glitch immunity and an internal 240 ms reset timeout timer. Its reference circuit maintains ±0.04 V accuracy over −40°C to +125°C, enabling stable reset assertion during slow-rising or noisy supply conditions.
It features a push-pull output stage capable of sourcing 150 μA at 0.8×VCC when VCC > VTH, and sinking 1.2 mA at 0.3 V when VCC = VTH min. The device operates continuously from VCC = 1.0 V to 5.5 V, supporting both 3 V and 5 V system rails without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.63 V (typical), ±0.04 V over full temperature range - ensures accurate power-fail detection for 2.7 V nominal supplies. |
| Supply Current | 17 μA (typical at VCC < 3.6 V, −40°C to +85°C) - enables battery-backed or energy-harvesting applications. |
| Reset Timeout | 240 ms (typical), 140–460 ms (min–max over −40°C to +85°C) - guarantees microprocessor initialization stability after power ramp. |
| VCC Operating Range | 1.0 V to 5.5 V - supports supervision down to near-zero VCC, critical for brownout recovery in low-voltage systems. |
| Output Type | Push-pull active-high RESET - eliminates need for external pull-up resistor and interfaces directly with CMOS/TTL inputs. |
| Temperature Range | −40°C to +125°C - qualified for under-hood automotive, industrial control, and high-reliability embedded environments. |
| Reset Output Low | 0.3 V at 1.2 mA sink - ensures solid logic-low level compatible with 1.8 V/3.3 V I/O standards. |
| Reset Output High | 0.8×VCC at 150 μA source - provides rail-to-rail compatible high-level drive across varying supply voltages. |
Pinout & Package
ADM810RARTZ-REEL7 is housed in a 3-lead SOT-23 (RT-3) package per JEDEC TO-236-AB standard, with 1.3 mm × 2.9 mm footprint and 1.1 mm height. Pin 1 = VCC, Pin 2 = RESET, Pin 3 = GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC) | Supply Input | Monitored power rail input; device operates from 1.0 V to 5.5 V and asserts reset if VCC drops below 2.63 V. |
| 2 (RESET) | Active-High Push-Pull Output | Drives high (≥0.8×VCC) when VCC ≥ threshold and timing complete; drives low (≤0.3 V) during reset assertion - no external pull-up required. |
| 3 (GND) | Ground Reference | Common return path for internal comparator and output driver; must be connected to system ground plane for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Glitch-immune reset comparator | Rejects transients ≤100 μs duration at 100 mV overdrive - prevents spurious resets from supply noise or ESD events. |
| 1 V minimum VCC operation | Guarantees functional reset assertion even as supply collapses to 1 V - essential for controlled shutdown in brownout scenarios. |
| 240 ms power-on reset timer | Internally generated delay holds RESET high until system clocks and peripherals stabilize - eliminates need for external RC timing network. |
| ±30 ppm/°C tempco | Ensures threshold drift < 0.1% over full temperature range - maintains tight reset window across harsh thermal environments. |
| RoHS-compliant SOT-23 | Lead-free, halogen-free packaging compliant with IPC/JEDEC J-STD-020 moisture sensitivity level 1 - suitable for lead-free reflow assembly. |

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, active-low push-pull output, 1.2 μA max supply current at 3.3 V | Requires inverted logic interface; lower quiescent current but no 1 V operation guarantee | Select when system design uses active-low reset input and ultra-low power is prioritized over brownout margin. |
| TPS3808G12DBVR | 1.2 V threshold (not 2.63 V), SOT-23-6, adjustable via external resistor, 1.8 μA typical supply current | Requires external resistor network and PCB space; not drop-in compatible due to different pin count and threshold | Select only if threshold flexibility and sub-μA sleep current outweigh need for direct replacement and fixed 2.63 V accuracy. |
Compared with MAX809RTRG+T and TPS3808G12DBVR, the ADM810RARTZ-REEL7 uniquely combines fixed 2.63 V accuracy, active-high push-pull output, guaranteed 1 V operation, and industrial temperature range in a 3-pin SOT-23 - making it optimal for cost-sensitive, space-constrained designs requiring minimal BOM changes and deterministic reset behavior.

FAQ
What is the reset output polarity of the ADM810RARTZ-REEL7?
The ADM810RARTZ-REEL7 features an active-high push-pull RESET output. When VCC is below the 2.63 V threshold or during the 240 ms power-on timeout, RESET is driven low (≤0.3 V); once VCC exceeds the threshold and timing completes, RESET is driven high (≥0.8×VCC). This eliminates the need for an external pull-up resistor and simplifies interface with most modern microcontrollers.
Does the ADM810RARTZ-REEL7 operate reliably at 1.0 V VCC?
Yes, the ADM810RARTZ-REEL7 is fully specified to operate and assert reset down to VCC = 1.0 V. Its internal circuitry remains functional and maintains comparator accuracy and timer integrity at this minimum supply, enabling robust brownout detection and controlled shutdown in low-voltage failure modes - a key differentiator versus many competing supervisors.
What is the guaranteed reset timeout range for ADM810RARTZ-REEL7 over temperature?
The ADM810RARTZ-REEL7 guarantees a reset timeout between 140 ms and 460 ms over −40°C to +85°C, with typical value of 240 ms. At higher temperatures (+85°C to +125°C), the range widens to 100 ms to 840 ms. This variation is fully characterized and documented in the datasheet's "RESET ACTIVE TIMEOUT PERIOD" specification table.
Can ADM810RARTZ-REEL7 replace ADM809RARTZ-REEL7 in an existing design?
No - ADM810RARTZ-REEL7 and ADM809RARTZ-REEL7 have opposite reset polarities: ADM810RARTZ-REEL7 outputs active-high RESET, while ADM809RARTZ-REEL7 outputs active-low RESET. Swapping them requires logic inversion in the host system or redesign of the reset interface; they are functionally complementary, not drop-in replacements.
Is ADM810RARTZ-REEL7 RoHS compliant and lead-free?
Yes, ADM810RARTZ-REEL7 is RoHS compliant and lead-free. The "Z" suffix in the part number explicitly denotes RoHS compliance per Analog Devices' ordering guide, and the device meets JEDEC J-STD-020 moisture sensitivity level 1 for lead-free reflow soldering processes.
