Product details
Overview
ADM1810-10AKS-RL7 from Analog Devices is a precision active-low push-pull microprocessor reset circuit designed to monitor 5 V power supplies and assert reset when voltage falls below 4.35 V (typical). It delivers 150 ms reset timeout, 8 mA sink current, <16 µA supply current at 5.5 V, and operates across −40°C to +105°C for industrial-grade embedded systems requiring reliable power-on initialization.
For engineers reviewing the ADM1810-10AKS-RL7 datasheet, ADM1810-10AKS-RL7 pinout, ADM1810-10AKS-RL7 application, or ADM1810-10AKS-RL7 equivalent, key selection criteria include trip point accuracy (±1.5% over temperature), SC70 package footprint compatibility, push-pull output drive capability without external pull-up, and guaranteed reset assertion during brownout conditions in microcontroller-based control units.
Technical Context
The ADM1810-10AKS-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 threshold is trimmed to 4.35 V (typical) with ±1.5% tolerance over full temperature range, enabling robust detection of 5 V supply undervoltage events.
This device uses an active-low push-pull output stage capable of sinking 8 mA while maintaining VOL ≤ 0.4 V, directly interfacing with standard microprocessor reset inputs. No external components are required for basic operation, and it supports immediate reset assertion on VCC fall and delayed release on VCC rise.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.35 V typical (−40°C to +105°C); ensures reliable detection of 5 V supply brownout before MCU malfunction. |
| Reset Timeout | 150 ms typical; provides sufficient hold time for power rail stabilization before releasing reset to processor. |
| Output Type | Active-low push-pull; drives reset input directly without external pull-up resistor or level-shifting circuitry. |
| Supply Current | ≤16 µA at VCC = 5.5 V; enables ultra-low-power monitoring in battery-backed or energy-constrained systems. |
| Output Sink Current | 8 mA at VCC ≥ 2.7 V, VOL ≤ 0.4 V; guarantees logic-low assertion under heavy capacitive load or noise margin requirements. |
| Operating Temp | −40°C to +105°C; qualified for industrial and automotive under-hood applications with extended thermal cycling. |
| VCC Range | 1.2 V to 5.5 V; allows operation even during deep brownout conditions while maintaining valid reset assertion. |
Pinout & Package
ADM1810-10AKS-RL7 is housed in a 3-lead SC70 (KS-3) package - compact, surface-mount, JEDEC-compliant, with 0.65 mm lead pitch and 2.00 mm × 1.25 mm footprint - optimized for space-constrained PCB layouts in portable and industrial controllers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RST) | Active-low reset output | Push-pull driver asserts logic low during undervoltage; holds low for 150 ms after VCC recovers above threshold. |
| 2 (VCC) | Supply voltage input | Monitored rail input; device draws current only from this pin and references its internal threshold to this node. |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry and output stage; must be low-impedance connection to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Precision trip point | 4.35 V typical with ±1.5% max variation over −40°C to +105°C - eliminates need for external calibration in 5 V systems. |
| Guaranteed reset timing | 150 ms minimum timeout ensures compliance with ARM Cortex-M, PIC, and STM32 reset hold-time requirements. |
| No external components | Push-pull output drives MCU reset pin directly - no pull-up resistor, capacitor, or debounce circuit required. |
| Ultra-low quiescent current | ≤16 µA at 5.5 V enables use in always-on subsystems without compromising battery life or standby power budget. |
| Robust ESD immunity | Qualified to >2 kV HBM per JEDEC JESD22-A114 - withstands handling and board assembly stress without latch-up. |
Applications
| Industrial PLC Controller | Automotive Body Control Module |
|---|---|
Use Scenario: Power sequencing in distributed I/O modules where 5 V supply may sag during relay switching or CAN transceiver wake-up. IC Role / Device Role / Timing Role: Monitors main 5 V rail and asserts active-low reset to ARM Cortex-M4F MCU until voltage stabilizes post-transient. Use Value: Prevents firmware crash during voltage dip by enforcing 150 ms reset hold, matching worst-case power supply recovery time. |
Use Scenario: Cold-cranking condition in 12 V vehicle electrical system where 5 V LDO output drops below specification during engine start. IC Role / Device Role / Timing Role: Detects 5 V rail collapse and holds microcontroller in reset until stable - critical for EEPROM write protection and CAN bus state integrity. Use Value: Trip point tolerance (±1.5%) ensures consistent behavior across temperature extremes encountered under hood. |
| Medical Infusion Pump | Network Edge Router |
Use Scenario: Dual-supply system where isolated 5 V logic rail powers safety-critical motor control ASICs and sensors. IC Role / Device Role / Timing Role: Provides fail-safe reset signal to watchdog timer and MCU upon 5 V undervoltage, preventing unintended actuation. Use Value: Active-low push-pull output eliminates external pull-up, reducing BOM count and improving reliability in Class II medical devices. |
Use Scenario: High-density switch fabric powered by multiple 5 V DC/DC converters; transient coupling causes localized rail droop. IC Role / Device Role / Timing Role: Local reset supervisor per voltage domain ensures individual FPGA or PHY resets independently without system-wide reboot. Use Value: SC70 package enables placement adjacent to each 5 V rail, minimizing trace inductance and improving noise immunity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage monitoring applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809SEUR+T | 4.63 V fixed threshold; ±2.5% tolerance; SOT-23-3 package; 14 µA max supply current. | Higher trip point unsuitable for 5 V systems operating near upper spec limit; requires layout change due to different pinout (VCC/GND/RST vs. RST/VCC/GND). | Select only if system design tolerates 4.63 V threshold and can accommodate pinout rework. |
| TPS3808G12DBVR | Adjustable threshold via external resistor divider; 1.2 V to 5.5 V range; 150 ms fixed delay; 2.5 µA typical supply current. | Requires two external resistors and bypass capacitor; higher design complexity but enables fine-tuning for non-standard rails. | Prefer when flexibility across multiple supply voltages justifies added BOM and layout overhead. |
Compared with MAX809SEUR+T and TPS3808G12DBVR, ADM1810-10AKS-RL7 offers tighter threshold accuracy (±1.5% vs. ±2.5%), guaranteed SC70 pinout compatibility, and true push-pull drive - eliminating both external components and layout risk in fixed 5 V monitoring roles.

FAQ
What is the exact reset threshold voltage for ADM1810-10AKS-RL7?
The ADM1810-10AKS-RL7 has a nominal reset threshold of 4.35 V (typical), with a guaranteed range of 4.25 V to 4.49 V across −40°C to +105°C per Table 1 in the Rev. F datasheet. This value is factory-trimmed and applies specifically to the ADM1810-10 variant, not other members of the ADM181x family.
Does ADM1810-10AKS-RL7 require an external pull-up resistor on the RST pin?
No. ADM1810-10AKS-RL7 features an active-low push-pull output stage, meaning it actively drives RST low during reset and high when released - no external pull-up resistor is needed. This distinguishes it from open-drain variants like ADM1811-10AKSZ-RL7, which do require external biasing.
Can ADM1810-10AKS-RL7 be used to monitor a 3.3 V supply?
No. ADM1810-10AKS-RL7 is specified for 5 V supply monitoring with a 4.35 V threshold. For 3.3 V systems, Analog Devices recommends ADM1815-10AKSZ-RL7 (2.88 V threshold) or ADM1817-10AKSZ-RL7 - both share the same SC70 package but are calibrated for lower-voltage rails.
What is the reset timeout duration of ADM1810-10AKS-RL7, and is it adjustable?
The ADM1810-10AKS-RL7 provides a fixed 150 ms typical reset timeout (100–250 ms min–max range) from VCC rising above threshold to RST deassertion. This delay is internally generated and not user-adjustable - ensuring consistent, predictable system initialization timing without external timing components.
Is ADM1810-10AKS-RL7 compatible with the SOT-23 package footprint?
No. ADM1810-10AKS-RL7 uses the SC70 (KS-3) package, which has different dimensions and pin spacing than SOT-23 (RT-3). While both are 3-lead surface-mount packages, SC70 measures 2.00 mm × 1.25 mm with 0.65 mm pitch, whereas SOT-23 is larger (2.90 mm × 1.30 mm, 0.95 mm pitch); direct PCB footprint substitution is not possible.
