Product details
Overview
ADM1810-5ARTZ-REEL from Analog Devices is a precision active-low push-pull microprocessor reset circuit designed to monitor 5 V power supplies. It features a 4.62 V typical reset threshold, 150 ms reset timeout, 9–16 µA supply current, and operates across −40°C to +105°C. It ensures safe system initialization in embedded controllers and industrial microprocessor systems.
For engineers reviewing the ADM1810-5ARTZ-REEL datasheet, ADM1810-5ARTZ-REEL pinout, ADM1810-5ARTZ-REEL application, or ADM1810-5ARTZ-REEL equivalent, key selection considerations include its SOT-23 package, active-low output drive capability (350 µA source / 8 mA sink), trip point tolerance (±0.13 V), and compatibility with standard microprocessor reset inputs without external components.
Technical Context
The ADM1810-5ARTZ-REEL implements a precision voltage comparator with internal bandgap reference and temperature-compensated hysteresis to detect VCC falling below 4.62 V (typ). Its internal 150 ms delay timer ensures stable power-up before releasing reset, preventing premature CPU execution.
It uses a push-pull output stage-no external pull-up required-and directly interfaces with TTL/CMOS reset inputs. The device draws only 9 µA at 3.6 V and 16 µA at 5.5 V, enabling low-power operation in battery-backed or energy-sensitive applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.62 V typical (min 4.50 V, max 4.75 V); ensures reliable detection of 5 V supply brownout. |
| Reset Timeout | 150 ms typical (100–250 ms range); guarantees sufficient power stabilization before system release. |
| Supply Current | 9 µA (typ) at 3.6 V; enables ultra-low quiescent power in always-on monitoring circuits. |
| Output Drive | 350 µA source / 8 mA sink; supports direct connection to most microprocessor reset pins. |
| Operating Temp | −40°C to +105°C; qualified for industrial and automotive under-hood environments. |
| Package | SOT-23 (RT-3); 3-pin, surface-mount, JEDEC-compliant footprint with 2.9 mm × 1.3 mm body. |
| VCC Range | 1.2 V to 5.5 V; allows operation even during deep brownout conditions prior to reset assertion. |
Pinout & Package
ADM1810-5ARTZ-REEL is housed in a 3-lead SOT-23 (RT-3) package per JEDEC TO-236-AB, with 0.95 mm pitch, coplanarity ≤ 0.10 mm, and thermal resistance θJA = 270°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output; held low while VCC < threshold, then remains low for 150 ms after VCC rises above threshold. |
| 2 | VCC | Supply voltage input and monitored rail; powers internal circuitry and serves as reference for threshold detection. |
| 3 | GND | Ground reference for all internal comparators, timers, and output stage; must be connected to system 0 V plane. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed Power-On Reset | 150 ms minimum timeout ensures CPU remains held until supply settles-no external RC timing needed. |
| Low Quiescent Current | 9 µA typical at 3.6 V enables use in always-on supervisory circuits without impacting system power budget. |
| Push-Pull Output | Eliminates need for external pull-up resistor; simplifies BOM and PCB layout for microprocessor reset interface. |
| Precision Threshold | ±0.13 V tolerance (4.50–4.75 V) over full temperature range ensures consistent 5 V supply monitoring behavior. |
| Wide Temperature Range | −40°C to +105°C operation supports deployment in industrial control panels and automotive ECUs. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD2T-T | 4.63 V threshold, 140 ms timeout, SOT-23, active-low open-drain output (requires external pull-up) | Lacks push-pull drive; needs 4.7 kΩ external resistor for same logic levels | Choose if cost sensitivity outweighs board space and BOM simplicity |
| TPS3808G15DBVR | 4.63 V threshold, 200 ms timeout, SOT-23, active-low push-pull, 1.4 µA quiescent current | Lower supply current but tighter 1.5% threshold accuracy (vs. ±2.8% for ADM1810) | Prefer for ultra-low-power designs where extended timeout is acceptable |

FAQ
What is the reset threshold voltage of the ADM1810-5ARTZ-REEL?
The ADM1810-5ARTZ-REEL has a nominal reset threshold of 4.62 V, with a guaranteed range of 4.50 V to 4.75 V over −40°C to +105°C. This value is factory-trimmed and specified in Table 1 of the Rev. F datasheet, making it suitable for monitoring standard 5 V power rails with margin for ripple and tolerance.
Does the ADM1810-5ARTZ-REEL require an external pull-up resistor?
No-the ADM1810-5ARTZ-REEL features an active-low push-pull output stage, eliminating the need for an external pull-up resistor. Its RST pin drives low actively and high actively, enabling direct interface with microprocessor reset inputs such as those on ARM Cortex-M or PIC microcontrollers.
What is the reset timeout duration for the ADM1810-5ARTZ-REEL?
The ADM1810-5ARTZ-REEL provides a fixed 150 ms typical reset timeout after VCC rises above the threshold, with a guaranteed range of 100 ms to 250 ms. This delay is internally generated and ensures the power supply stabilizes before releasing the microprocessor from reset.
Is the ADM1810-5ARTZ-REEL compatible with 3.3 V microcontrollers?
Yes-the ADM1810-5ARTZ-REEL's RST output swings rail-to-rail (VCC to GND) and is fully compatible with 3.3 V logic inputs when VCC = 5 V. Its output high voltage exceeds 4.4 V (VCC − 0.1 V), well above the VIH threshold of standard 3.3 V CMOS inputs.
What package type does the ADM1810-5ARTZ-REEL use?
The ADM1810-5ARTZ-REEL uses the 3-lead SOT-23 (RT-3) package, a JEDEC TO-236-AB compliant surface-mount outline with 0.95 mm lead pitch, 2.9 mm × 1.3 mm body size, and RoHS-compliant matte tin lead finish (denoted by "Z" in the part number).
