Product details
Overview
ADM1810-5ART-REEL from Analog Devices is a precision microprocessor reset circuit with active-low push-pull output, 4.62 V typical reset threshold, 150 ms reset timeout, and operation over −40°C to +105°C. It monitors 5 V power supplies in embedded controllers and ensures safe system initialization by holding reset until supply stabilization.
For engineers reviewing the ADM1810-5ART-REEL datasheet, ADM1810-5ART-REEL pinout, ADM1810-5ART-REEL application, or ADM1810-5ART-REEL equivalent, key selection criteria include trip point accuracy (±130 mV), ultra-low quiescent current (9–16 µA), SOT-23 package compatibility, and push-pull drive capability without external components.
Technical Context
The ADM1810-5ART-REEL integrates a precision voltage reference, comparator, and 150 ms delay timer to generate a clean, glitch-free reset signal during power-up and brownout conditions. Its internal hysteresis prevents chatter near the trip point, and the push-pull output drives standard CMOS/TTL reset inputs directly.
It operates across the full industrial temperature range with supply voltage tolerance from 1.2 V to 5.5 V, enabling use in systems where VCC may dip below nominal during startup or transient events - critical for reliable boot sequencing in automotive and industrial microcontrollers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.62 V typical (min 4.50 V, max 4.75 V); precisely targets 5 V supply monitoring with ±2.8% tolerance. |
| Reset Timeout | 150 ms typical (100–250 ms); guarantees sufficient time for power supply stabilization before releasing reset. |
| Supply Range | 1.2 V to 5.5 V; supports operation even during deep brownout or low-VCC startup sequences. |
| Quiescent Current | 9–16 µA at 5.5 V; enables battery-backed or ultra-low-power applications without compromising reset integrity. |
| Output Type | Active-low push-pull; delivers full rail-to-rail logic levels with 350 µA source / 8 mA sink capability - no pull-up required. |
| Operating Temp | −40°C to +105°C; qualified for under-hood automotive, industrial PLC, and harsh-environment embedded systems. |
Pinout & Package
ADM1810-5ART-REEL is housed in a 3-lead SOT-23 (RT-3) package, measuring 2.90 mm × 1.30 mm × 1.02 mm, with gull-wing leads and JEDEC TO-236-AB compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST | Active-low reset output | Drives microcontroller RESET# input low during undervoltage; remains asserted for 150 ms after VCC rises above threshold. |
| VCC | Supply voltage input | Monitored power rail (1.2–5.5 V); also powers internal circuitry - no separate bias supply needed. |
| GND | Ground reference | 0 V return path for both monitor circuit and output stage; must be low-impedance to ensure accurate threshold detection. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed threshold | 4.62 V ±130 mV ensures precise 5 V supply monitoring without external resistor networks or calibration. |
| Integrated 150 ms delay | Eliminates need for external RC timing components - reduces BOM count and PCB area in space-constrained designs. |
| Push-pull output stage | Directly interfaces with standard microprocessor reset inputs (e.g., ARM Cortex-M, PIC, STM32) without external pull-up resistors. |
| Ultra-low supply current | As low as 9 µA at 3.6 V enables use in always-on, battery-powered supervisory circuits with multi-year runtime. |
| Wide temperature operation | Specified from −40°C to +105°C supports deployment in automotive engine control units and industrial motor drives. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD2T-T | 4.63 V threshold, 140 ms reset timeout, SOT-23-3, 20 µA max ICC | Same 5 V monitoring function but higher quiescent current and tighter timeout spec | Select when legacy MAXIM footprint compatibility is required and 10 µA extra current is acceptable. |
| TPS3808G01DBVR | 4.63 V threshold, adjustable delay (1.25 ms to 10 s), 1.5 µA typical ICC, SOT-23-6 | Offers programmable timeout and lower current, but requires external capacitor and occupies larger footprint | Choose for ultra-low-power designs needing configurable reset duration, accepting added component count and pin count. |
Compared with MAX809TRD2T-T and TPS3808G01DBVR, the ADM1810-5ART-REEL delivers tighter threshold tolerance (±2.8% vs ±3.1%), lower typical supply current (9 µA vs 20 µA), and fixed 150 ms delay optimized for standard microprocessor boot timing - all in a minimal 3-pin SOT-23 footprint.

FAQ
What is the exact reset threshold voltage of the ADM1810-5ART-REEL?
The ADM1810-5ART-REEL has a factory-trimmed reset threshold of 4.62 V typical, with a guaranteed range of 4.50 V to 4.75 V at −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 precise 5 V supply monitoring without external calibration.
Does the ADM1810-5ART-REEL require an external pull-up resistor on the RST pin?
No, the ADM1810-5ART-REEL does not require an external pull-up resistor because it features an active-low push-pull output stage. The RST pin actively drives low during reset and high when released, delivering rail-to-rail logic levels with 350 µA source and 8 mA sink capability - fully compatible with standard microprocessor reset inputs.
Can the ADM1810-5ART-REEL operate with supply voltages below 5 V?
Yes, the ADM1810-5ART-REEL operates with supply voltages from 1.2 V to 5.5 V, as specified in the Absolute Maximum Ratings and Electrical Characteristics tables. Its internal reference and comparator remain functional down to 1.2 V, enabling reliable reset generation even during severe brownout conditions on the monitored 5 V rail.
What is the reset timeout duration of the ADM1810-5ART-REEL, and is it adjustable?
The ADM1810-5ART-REEL provides a fixed 150 ms typical reset timeout (100–250 ms over temperature), which is internally generated and non-adjustable. This delay ensures sufficient time for power supply stabilization before releasing the reset signal - a design choice that eliminates external timing components and improves system reliability.
Is the ADM1810-5ART-REEL RoHS compliant and lead-free?
Yes, the ADM1810-5ART-REEL is RoHS compliant and lead-free. The "Z" suffix in alternate part numbers (e.g., ADM1810-5ARTZ-REEL) explicitly denotes RoHS compliance, and the ordering guide confirms that all SOT-23 variants including ADM1810-5ART-REEL meet JEDEC and RoHS requirements per Analog Devices' manufacturing standards.
