Product details
Overview
ADM1810-5AKSZ-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, ±1.5% threshold accuracy over −40°C to +105°C, and ultra-low 9–16 µA supply current. It ensures safe system initialization in embedded controllers and automotive ECUs where reliable power-on reset is critical.
For engineers reviewing the ADM1810-5AKSZ-REEL datasheet, ADM1810-5AKSZ-REEL pinout, ADM1810-5AKSZ-REEL application, or ADM1810-5AKSZ-REEL equivalent, key selection criteria include trip point tolerance, reset timeout stability across temperature, push-pull output drive capability, SC70 package footprint compatibility, and industrial-grade operating range support.
Technical Context
The ADM1810-5AKSZ-REEL implements a precision bandgap reference with temperature-compensated comparator and internal 150 ms delay timer. Its active-low push-pull output drives microprocessor reset inputs directly without external pull-up resistors or level-shifting components.
It operates across the full industrial temperature range (−40°C to +105°C) with supply voltage support from 1.2 V to 5.5 V, enabling use in brown-out detection and cold-start scenarios where VCC may dip below nominal before stabilizing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.62 V typical (4.50–4.75 V min/max); precisely monitors 5 V rails for undervoltage lockout |
| Reset Timeout | 150 ms typical (100–250 ms); guarantees stable power-up before releasing reset to CPU |
| Supply Current | 9–16 µA at 5.5 V; enables low-power always-on monitoring in battery-backed systems |
| Output Type | Active-low push-pull; sinks 8 mA and sources 350 µA - directly interfaces with ARM, PIC, and x86 reset pins |
| Operating Temp | −40°C to +105°C; qualified for under-hood automotive and industrial control environments |
| Package | SC70-3 (KS-3); 2.2 mm × 1.35 mm footprint - space-efficient for compact PCB layouts |
Pinout & Package
ADM1810-5AKSZ-REEL is housed in a 3-lead SC70 (KS-3) package with gull-wing leads, JEDEC-compliant outline, and 0.65 mm lead pitch. The package supports reflow soldering and offers 146°C/W thermal impedance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST | Active-low reset output | Drives low during VCC < threshold and remains low for 150 ms after VCC rises above threshold; push-pull structure eliminates need for external pull-up |
| VCC | Supply input / monitored rail | Both powers the device and serves as the voltage being monitored; operates down to 1.2 V for brown-out detection |
| GND | Ground reference | 0 V return path for internal reference and output stage; must be connected to system ground plane for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed 150 ms reset timeout | Ensures microprocessor clocks and peripherals stabilize before release - prevents premature execution |
| ±1.5% reset threshold accuracy | Minimizes false resets due to tolerance drift; meets tight margin requirements in 5 V logic systems |
| Ultra-low quiescent current | 9 µA minimum draw extends battery life in always-on monitoring applications such as telematics modules |
| Industrial temperature grade | Validated operation from −40°C to +105°C supports deployment in engine control units and factory automation |
| Direct interface capability | Push-pull RST output eliminates external components - reduces BOM count and layout area in space-constrained designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809SEUR+T | 4.63 V threshold, 140 ms timeout, SOT-23-3 package, higher 20 µA supply current | Lacks extended temperature rating (−40°C to +85°C only); not qualified for automotive under-hood use | Select when cost sensitivity outweighs industrial temp requirement and board space allows SOT-23 |
| TPS3808G50DBVR | 4.63 V threshold, adjustable 20–300 ms timeout via capacitor, 1.4 µA quiescent current | Requires external timing capacitor; active-low open-drain output needs pull-up resistor | Choose for ultra-low power designs where programmable timeout and flexible output topology justify added components |

FAQ
What is the exact reset threshold voltage of the ADM1810-5AKSZ-REEL?
The ADM1810-5AKSZ-REEL has a nominal reset threshold of 4.62 V, with a guaranteed range of 4.50 V (min) to 4.75 V (max) across −40°C to +105°C. This precise trip point is optimized for reliable monitoring of standard 5 V power rails in industrial and automotive applications, and is specified in Table 1 of the Rev. F datasheet.
Does the ADM1810-5AKSZ-REEL require an external pull-up resistor on the RST pin?
No, the ADM1810-5AKSZ-REEL does not require an external pull-up resistor. Its active-low push-pull output actively drives both high and low states - sourcing up to 350 µA and sinking up to 8 mA - enabling direct connection to microprocessor reset inputs without additional components.
What is the operating temperature range supported by the ADM1810-5AKSZ-REEL?
The ADM1810-5AKSZ-REEL is fully specified and qualified for operation from −40°C to +105°C. This industrial temperature range is confirmed in the Ordering Guide (Page 9) and Absolute Maximum Ratings (Page 4), making it suitable for under-hood automotive, factory automation, and outdoor infrastructure applications.
How does the reset timeout behave during power-up versus power-down events?
During power-up, the ADM1810-5AKSZ-REEL asserts reset for 150 ms (typical) after VCC rises above the threshold. During power-down, reset is asserted within 10 µs of VCC falling below threshold. Both behaviors are characterized in the Timing Diagrams (Pages 7–8) and ensure fast fault response and controlled startup sequencing.
Is the ADM1810-5AKSZ-REEL RoHS compliant and halogen-free?
Yes, the "Z" suffix in ADM1810-5AKSZ-REEL explicitly denotes RoHS compliance per Analog Devices' packaging nomenclature (Ordering Guide footnote 2, Page 12). The part meets EU RoHS Directive 2011/65/EU and is manufactured using halogen-free molding compounds.
