Product details
Overview
ADM1810-5AKS-RL7 from Analog Devices is a precision active-low push-pull microprocessor reset circuit designed for 5 V supply monitoring in embedded systems. It features a 4.62 V typical reset threshold, 150 ms reset timeout, ±1.5% trip accuracy over −40°C to +105°C, and ultra-low 9–16 µA supply current - enabling reliable power-on initialization in industrial controllers and automotive ECUs.
For engineers reviewing the ADM1810-5AKS-RL7 datasheet, ADM1810-5AKS-RL7 pinout, ADM1810-5AKS-RL7 application, or ADM1810-5AKS-RL7 equivalent, key selection criteria include its SC70-3 package footprint, guaranteed reset assertion during VCC brownout, compatibility with standard microprocessor reset inputs without external components, and support for high-temperature operation up to +105°C.
Technical Context
The ADM1810-5AKS-RL7 integrates a precision voltage reference, comparator with hysteresis, and a 150 ms monostable delay circuit to ensure safe system startup after power stabilization. Its internal architecture guarantees reset assertion while VCC remains below 4.62 V (typical), with a minimum 100 ms active duration and tight ±1.5% trip tolerance across temperature.
This device operates within a 1.2–5.5 V supply range but is specifically configured for 5 V rail monitoring. Its active-low push-pull output drives directly into most µP reset pins, eliminating need for pull-up resistors or level-shifting circuitry - a critical advantage in space-constrained industrial and automotive PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.62 V typical (4.50–4.75 V min/max); ensures reliable detection of 5 V supply undervoltage before system corruption |
| Reset Timeout | 150 ms typical (100–250 ms); provides sufficient time for power rail stabilization before releasing reset |
| Supply Current | 9–16 µA at 5.5 V; enables low-power operation in battery-backed or energy-sensitive applications |
| Operating Temp | −40°C to +105°C; qualified for under-hood automotive and industrial control environments |
| Output Type | Active-low push-pull; delivers full-rail logic levels without external biasing components |
| Package | SC70-3 (KS-3); 2.0 × 2.1 mm footprint, compatible with high-density SMT assembly |
| Reset Propagation | <10 µs falling edge response; ensures fast reaction to sudden VCC collapse |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST | Active-low reset output | Drives low when VCC < 4.62 V; holds low for 150 ms after VCC rises above threshold - directly interfaces µP reset input |
| VCC | Supply voltage input | Monitored 5 V rail; also powers internal circuitry - no separate bias supply required |
| GND | Ground reference | 0 V return path for both monitor and output stages; must be low-impedance to ensure accurate threshold tracking |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed reset assertion during brownout | Asserts RST low whenever VCC drops below 4.62 V (typ), preventing erratic µP behavior during unstable power |
| No external components required | Push-pull output eliminates need for pull-up resistor - reduces BOM count and board area in compact designs |
| High-temperature reliability | Specified performance maintained from −40°C to +105°C - suitable for engine control units and industrial PLCs |
| Precision trip point tolerance | ±1.5% over full temperature range - minimizes false resets and improves system robustness vs. generic supervisors |
| Ultra-low quiescent current | 9 µA minimum supply draw - extends battery life in always-on monitoring applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD2T | 4.63 V reset threshold, SOT-23-3 package, 12 µA max supply current | Same 5 V monitoring function but lacks extended temperature rating (−40°C to +85°C only) | Select when cost sensitivity outweighs extended temp requirement and SOT-23 footprint is preferred |
| TPS3808G01DBVR | 4.63 V threshold, adjustable delay option, 1.2–6.0 V supply range, 16 µA typical current | Supports wider input voltage range and offers programmable reset timeout (up to 200 s), but requires external capacitor | Choose when design requires configurable delay or multi-rail supervision capability beyond fixed 150 ms |
Compared with MAX809TRD2T and TPS3808G01DBVR, the ADM1810-5AKS-RL7 delivers tighter trip accuracy (±1.5% vs. ±2.5%), guaranteed +105°C operation, and zero-component interface - making it optimal for mission-critical industrial and automotive applications where reliability trumps configurability.

FAQ
What is the exact reset threshold voltage of ADM1810-5AKS-RL7?
The ADM1810-5AKS-RL7 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 ensures reliable detection of 5 V supply brownout conditions without premature or delayed reset assertion - a key specification verified in Table 1 of the Rev. F datasheet.
Does ADM1810-5AKS-RL7 require external components for basic operation?
No, ADM1810-5AKS-RL7 operates autonomously with no external components required. Its active-low push-pull output drives directly into microprocessor reset inputs, and its internal voltage reference and timing circuit eliminate the need for external capacitors or resistors - simplifying design and improving long-term reliability compared to RC-based reset solutions.
What package type is used for ADM1810-5AKS-RL7?
ADM1810-5AKS-RL7 uses the SC70-3 (KS-3) package: a 3-lead, gull-wing surface-mount outline measuring 2.0 mm × 2.1 mm × 0.9 mm, compliant with EIAJ SC70 standards. This compact footprint supports high-density PCB layouts common in automotive and portable industrial electronics.
Can ADM1810-5AKS-RL7 be used for 3.3 V supply monitoring?
No, ADM1810-5AKS-RL7 is specifically configured for 5 V supply monitoring with a 4.62 V reset threshold. For 3.3 V rails, Analog Devices recommends the ADM1815-5AKS-RL7 (3.06 V threshold) or ADM1817-5AKS-RL7 - both part of the same family but with different internal reference settings and validated trip points.
What is the reset timeout duration of ADM1810-5AKS-RL7 after VCC rises above threshold?
The ADM1810-5AKS-RL7 asserts reset for a guaranteed minimum of 100 ms and typical duration of 150 ms after VCC rises above the 4.62 V threshold, with an upper limit of 250 ms. This fixed delay ensures adequate power rail stabilization before releasing the microprocessor from reset - a critical timing parameter documented in the "RESET ACTIVE TIME" row of Table 1.
