Product details
Overview
ADM1817-5ARTZ-REEL from Analog Devices is a microprocessor reset circuit with active-high push-pull output, 3.06 V typical reset threshold, 150 ms reset timeout, and operation across −40°C to +105°C. It monitors 3.3 V/3 V/2.5 V supplies in embedded controllers and ensures safe power-up initialization in industrial microprocessor systems.
For engineers reviewing the ADM1817-5ARTZ-REEL datasheet, ADM1817-5ARTZ-REEL pinout, ADM1817-5ARTZ-REEL application, or ADM1817-5ARTZ-REEL equivalent, key selection criteria include reset threshold accuracy (±1.5% over temperature), ultra-low quiescent current (9–16 µA), SOT-23 package compatibility, and direct interface capability with MCU reset inputs without external components.
Technical Context
The ADM1817-5ARTZ-REEL integrates a precision voltage reference, comparator, and 150 ms internal delay timer to generate a clean, glitch-free active-high reset signal. Its trip point is factory-trimmed to 3.06 V (typical) with ±1.5% tolerance over full temperature range.
It operates from 1.2 V to 5.5 V supply, draws only 9 µA at 5.5 V when VCC > VTH, and delivers 350 µA source current during reset assertion-enabling direct drive of most microcontroller reset pins without pull-up resistors or level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.06 V typical (2.98–3.15 V min/max); precisely monitors 3.3 V supply rails with margin for ripple and droop |
| Reset Timeout | 150 ms typical (100–250 ms); guarantees stable power supply before system release |
| Supply Range | 1.2 V to 5.5 V; supports wide-input monitoring including low-voltage logic domains |
| Quiescent Current | 9 µA at 5.5 V (VCC > VTH); enables battery-backed or always-on system monitoring |
| Output Type | Active-high push-pull; eliminates need for external pull-up and simplifies PCB layout |
| Operating Temp | −40°C to +105°C; qualified for industrial and automotive under-hood environments |
| Package | SOT-23 (RT-3); 3-pin, 2.9 mm × 1.3 mm footprint compatible with high-density layouts |
Pinout & Package
ADM1817-5ARTZ-REEL uses a 3-lead SOT-23 (RT-3) package with JEDEC TO-236-AB compliance, 1.3 mm max height, and 0.95 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-high push-pull reset output; remains high while VCC < VTH and stays high for 150 ms after VCC rises above threshold |
| 2 | VCC | Supply input and monitored voltage rail; powers internal circuitry and serves as reference for threshold detection |
| 3 | GND | Ground reference for all internal comparators, reference, and output stage; must be low-impedance connection |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed threshold | 3.06 V ±1.5% over −40°C to +105°C eliminates need for external calibration or trimming resistors |
| Integrated 150 ms delay | Guarantees minimum power stabilization time before releasing reset-no external RC timing network required |
| Push-pull RST output | 350 µA source drive capability directly interfaces with ARM Cortex-M, PIC, and STM32 reset inputs without pull-up |
| Ultra-low ICC | 9 µA max at 5.5 V enables use in energy-sensitive applications such as remote sensors and battery-powered controllers |
| RoHS-compliant packaging | Z-suffix indicates lead-free, halogen-free SOT-23 construction meeting IPC/JEDEC J-STD-020 reflow requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD2T | 3.08 V reset threshold, 140 ms timeout, SOT-23-3, 20 µA ICC | Higher threshold tolerance (±2.5%), no extended temp grade beyond +85°C | Acceptable for commercial-grade 3.3 V systems where extended temperature operation is not required |
| TPS3808G30DBVR | 3.0 V threshold, 200 ms timeout, SOT-23-6, 12 µA ICC, enable input | Requires external enable control; larger footprint; higher BOM cost | Preferred when system-level reset sequencing or manual override is needed beyond basic supply monitoring |
Compared with MAX809TRD2T and TPS3808G30DBVR, the ADM1817-5ARTZ-REEL offers tighter threshold accuracy over industrial temperature range and lower quiescent current-making it optimal for space-constrained, battery-aware, or thermally demanding applications where deterministic reset behavior is critical.

FAQ
What is the exact reset threshold voltage of the ADM1817-5ARTZ-REEL?
The ADM1817-5ARTZ-REEL has a factory-trimmed reset threshold of 3.06 V typical, with guaranteed limits of 2.98 V (min) and 3.15 V (max) over −40°C to +105°C. This value is specified in Table 1 of the Rev. F datasheet and applies exclusively to the -5 variant, confirming its suitability for 3.3 V supply monitoring with adequate headroom.
Does the ADM1817-5ARTZ-REEL require external components to function?
No, the ADM1817-5ARTZ-REEL requires no external components. Its active-high push-pull output drives MCU reset inputs directly, the 150 ms reset timeout is fully internal, and the precision voltage reference is monolithically integrated-enabling drop-in deployment in SOT-23 footprints without resistors, capacitors, or diodes.
Is the ADM1817-5ARTZ-REEL RoHS compliant?
Yes, the ADM1817-5ARTZ-REEL is RoHS compliant. The "Z" suffix in the part number explicitly denotes lead-free, halogen-free construction per EU Directive 2011/65/EU, and it meets IPC/JEDEC J-STD-020 moisture sensitivity level 1 requirements for standard reflow assembly.
Can the ADM1817-5ARTZ-REEL monitor voltages other than 3.3 V?
Yes-the ADM1817-5ARTZ-REEL is rated for supply monitoring across 1.2 V to 5.5 V, but its 3.06 V threshold is optimized for 3.3 V rails. For 2.5 V or 3 V supplies, variants like ADM1817-10 (2.88 V) or ADM1817-20 (2.55 V) are specified; using ADM1817-5ARTZ-REEL on lower rails risks premature or missed reset assertion.
What is the maximum sink current capability of the ADM1817-5ARTZ-REEL RST pin?
The ADM1817-5ARTZ-REEL RST pin does not provide sink current-it is an active-high push-pull output. When asserted (low), it sinks up to 8 mA (per Table 1, applicable to ADM1812/ADM1817 during reset assertion). However, in normal operation (high), it sources 350 µA. This architecture avoids reliance on external pull-ups and ensures fast, controlled rise/fall times.
