Product details
Overview
ADM1810-10AKS-REEL from Analog Devices is an active-low push-pull microprocessor reset circuit monitoring 4.35 V nominal supply voltage, with 150 ms reset timeout, −40°C to +105°C operating range, and SC70-3 package. It ensures safe system initialization in embedded controllers and industrial microprocessor systems by holding reset until power stabilizes.
For engineers reviewing the ADM1810-10AKS-REEL datasheet, ADM1810-10AKS-REEL pinout, ADM1810-10AKS-REEL application, or ADM1810-10AKS-REEL equivalent, key selection criteria include trip point tolerance (±0.13 V), low quiescent current (9–16 µA), push-pull output drive capability (350 µA source / 8 mA sink), and compatibility with 3.3 V/5 V logic interfaces.
Technical Context
The ADM1810-10AKS-REEL integrates a precision voltage reference, comparator with hysteresis, and a 150 ms monostable delay circuit to generate a clean, glitch-free active-low reset signal. Its internal architecture guarantees reset assertion during power-up until VCC exceeds 4.35 V (typ) and remains asserted for ≥150 ms after threshold crossing.
This device operates without external components-directly interfacing with microprocessor reset inputs-and features guaranteed performance across −40°C to +105°C, with supply voltage range of 1.2 V to 5.5 V and reset timeout variation ≤ ±50 ms over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.35 V typical (min 4.25 V, max 4.49 V); enables reliable monitoring of 5 V supplies with margin against ripple and dropout. |
| Reset Timeout | 150 ms typical (100–250 ms range); provides sufficient time for power supply stabilization before releasing processor reset. |
| Supply Voltage Range | 1.2 V to 5.5 V; supports operation down to brown-out conditions while maintaining valid reset assertion. |
| Quiescent Current | 9–16 µA at 5.5 V; minimizes standby power impact in battery-backed or energy-sensitive systems. |
| Output Type | Active-low push-pull; drives reset input directly without pull-up resistor, reducing BOM count and layout complexity. |
| Temperature Range | −40°C to +105°C; qualified for industrial and automotive under-hood applications requiring extended thermal robustness. |
| Reset Propagation Delay | 100 µs max on power-up rise; ensures deterministic timing behavior for synchronous system startup. |
Pinout & Package
ADM1810-10AKS-REEL is housed in a 3-lead SC70 (KS-3) package - 2.00 mm × 1.25 mm × 0.9 mm, JEDEC-compliant, surface-mountable with coplanarity ≤ 0.10 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST | Active-low reset output | Push-pull driver asserts low during undervoltage and holds low for 150 ms post-threshold crossing; compatible with standard µP reset inputs. |
| VCC | Supply voltage input | Monitored rail input; also powers internal circuitry; accepts 1.2 V to 5.5 V, enabling use in mixed-voltage systems. |
| GND | Ground reference | 0 V return path for all internal biasing and output switching; must be low-impedance to ensure accurate threshold detection. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed 150 ms reset timeout | Ensures consistent power stabilization window across full temperature and voltage range-no external RC timing required. |
| 4.35 V trip point with ±0.13 V tolerance | Accurately targets 5 V supply monitoring with headroom for line regulation and transient rejection. |
| Push-pull active-low output | Eliminates need for external pull-up resistor, simplifying PCB layout and improving noise immunity vs. open-drain alternatives. |
| Ultra-low quiescent current (9 µA min) | Reduces system-level standby power-critical for always-on industrial controllers and remote sensors. |
| SC70-3 package | Enables high-density placement in space-constrained applications such as portable instrumentation and modular PLC I/O. |
Applications
| Industrial PLC Controller | Automotive Body Control Module |
|---|---|
Use Scenario: Power sequencing in a DIN-rail mounted programmable logic controller where main 5 V rail must stabilize before FPGA and MCU initialization. IC Role / Device Role / Timing Role: Primary reset supervisor asserting active-low signal to ARM Cortex-M7 reset pin during cold start and brown-out events. Use Value: 150 ms fixed timeout prevents premature release of reset, avoiding firmware lockup due to unstable 5 V rail during capacitor charging. | Use Scenario: Reset coordination in a vehicle door module powered from switched 5 V bus subject to load dump and cranking transients. IC Role / Device Role / Timing Role: Voltage monitor detecting dips below 4.35 V and generating a clean, debounced reset pulse to safeguard microcontroller operation. Use Value: ±0.13 V trip tolerance ensures reliable detection of sustained undervoltage without false triggering from short-duration spikes. |
| Medical Diagnostic Handheld | Smart Energy Meter |
Use Scenario: Battery-backed operation where main 5 V DC-DC output must reach regulation before initializing ADC and display subsystems. IC Role / Device Role / Timing Role: System-level reset generator interfacing directly with reset input of ultra-low-power MSP430 microcontroller. Use Value: 9 µA quiescent current extends backup runtime during AC loss, while SC70-3 footprint saves board area in compact enclosure. | Use Scenario: Tamper-resistant meter with isolated power domains; 5 V auxiliary rail powers metrology ASIC and secure element. IC Role / Device Role / Timing Role: Dedicated reset supervisor ensuring synchronized startup of isolated communication interface and measurement core. Use Value: −40°C to +105°C rating supports outdoor deployment in uncontrolled environments without derating or thermal compensation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage monitor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD2T | 4.63 V reset threshold, SOT-23-3 package, 140 ms timeout, 1.2–5.5 V supply range | Higher trip point unsuitable for 4.35 V margin-critical 5 V rails; requires PCB redesign for SOT-23 footprint | Select only if system tolerates tighter 4.63 V threshold and layout accommodates different pad geometry. |
| TPS3808G12DBVR | 4.38 V threshold, 200 ms timeout, adjustable via external capacitor, 0.8–6.0 V supply | Timeout not factory-fixed; requires external component and adds design validation overhead | Prefer when variable timeout is needed; avoid if strict 150 ms deterministic behavior is required. |
Compared with MAX809TRD2T and TPS3808G12DBVR, the ADM1810-10AKS-REEL delivers precise 4.35 V detection with guaranteed 150 ms timing in a compact SC70 package-enabling drop-in replacement in space-constrained industrial designs without layout or timing recalibration.

FAQ
What is the exact reset threshold voltage of the ADM1810-10AKS-REEL?
The ADM1810-10AKS-REEL has a nominal reset threshold of 4.35 V, with guaranteed minimum and maximum values of 4.25 V and 4.49 V respectively, measured across −40°C to +105°C and specified in Table 1 of the Rev. F datasheet.
Does the ADM1810-10AKS-REEL require external components to operate?
No, the ADM1810-10AKS-REEL operates autonomously with no external components required. Its integrated 150 ms timer, precision reference, and push-pull output enable direct connection to microprocessor reset inputs-eliminating resistors, capacitors, or diodes from the reset circuit.
What package type is used for the ADM1810-10AKS-REEL?
The ADM1810-10AKS-REEL uses the SC70-3 (KS-3) package: a 3-lead, 2.00 mm × 1.25 mm surface-mount outline compliant with EIAJ SC70 standards and featuring 0.65 mm lead pitch and ≤0.10 mm coplanarity.
Can the ADM1810-10AKS-REEL be used with a 3.3 V microprocessor reset input?
Yes, the ADM1810-10AKS-REEL's active-low push-pull output drives to <0.4 V when asserted and to VCC − 0.1 V when released-ensuring full logic-level compatibility with 3.3 V systems when powered from a 3.3 V or higher supply rail.
How does the ADM1810-10AKS-REEL handle power supply transients?
The ADM1810-10AKS-REEL incorporates comparator hysteresis and a minimum 10 µs response time on rising edges, rejecting sub-10 µs transients. Its 4.35 V threshold with ±0.13 V tolerance ensures immunity to typical 5 V rail ripple (<50 mV p-p) without spurious reset assertion.
