Product details
Overview
ADM1810-10AKSZ-RL7 from Analog Devices is a precision active-low push-pull microprocessor reset circuit designed to monitor 5 V power supplies in embedded systems. It features a 4.35 V typical reset threshold, 150 ms reset timeout, ±1.5% trip point accuracy over −40°C to +105°C, and ultra-low 4–10 µA supply current at 3.6 V - enabling reliable cold-start initialization for industrial controllers and automotive ECUs.
For engineers reviewing the ADM1810-10AKSZ-RL7 datasheet, ADM1810-10AKSZ-RL7 pinout, ADM1810-10AKSZ-RL7 application, or ADM1810-10AKSZ-RL7 equivalent, key selection criteria include guaranteed reset assertion during brown-out, compatibility with standard microprocessor reset inputs without external components, and SC70 package suitability for space-constrained PCB layouts.
Technical Context
The ADM1810-10AKSZ-RL7 integrates a precision voltage reference, comparator, and 150 ms internal reset timer to ensure safe system startup after power-on or recovery from undervoltage. Its active-low push-pull output drives directly into most µP reset pins, eliminating need for pull-up resistors or level-shifting circuitry.
Designed for high-reliability monitoring of 5 V rails, it operates across −40°C to +105°C with trip point tolerance of ±1.5% (typical) and exhibits <10 µs response time on rising VCC edges - critical for deterministic boot sequencing in safety-critical applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.35 V typical (−40°C to +105°C); ensures robust detection of 5 V supply sag below 4.25 V min. |
| Reset Timeout | 150 ms typical; guarantees stable power rail before releasing reset to prevent premature CPU execution. |
| Supply Current | 4 µA typical at 3.6 V; enables low-power operation in always-on subsystems without battery drain. |
| Output Type | Active-low push-pull; sinks 8 mA and sources 350 µA - directly interfaces with ARM, PIC, and x86 reset inputs. |
| Operating Temp | −40°C to +105°C; qualified for under-hood automotive and industrial control environments. |
| Package | SC70-3 (KS-3); 2.0 mm × 2.1 mm footprint with 0.65 mm pitch - supports high-density layout. |
Pinout & Package
ADM1810-10AKSZ-RL7 is housed in a 3-lead SC70 (KS-3) package with gull-wing leads, JEDEC-compliant outline, and coplanarity ≤0.10 mm. Pin 1 = RST (active-low reset output), Pin 2 = VCC (monitored supply input), Pin 3 = GND (0 V reference).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST | Active-low reset output | Drives low when VCC < 4.25 V (min); holds low for 150 ms after VCC rises above threshold - ensures deterministic µP reset timing. |
| VCC | Monitored supply input | Accepts 1.2 V to 5.5 V; internally powers reference and comparator - no separate bias supply required. |
| GND | Ground reference | 0 V return path for all internal circuits; must be connected to system ground plane for accurate threshold tracking. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed reset assertion during brown-out | Trips at 4.25 V min (−40°C to +105°C), preventing erratic CPU behavior during 5 V rail collapse. |
| Direct µP interface capability | Push-pull output eliminates need for external pull-up resistor - reduces BOM count and layout area. |
| Factory-trimmed threshold accuracy | ±1.5% typical trip point tolerance - avoids calibration overhead in production test. |
| Ultra-low quiescent current | 4 µA at 3.6 V enables use in battery-backed or energy-harvesting systems without compromising runtime. |
| High-temp reliability | Qualified to +105°C ambient - suitable for engine control modules and industrial PLCs without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD2T | 4.63 V reset threshold (±2.5%), SOT-23-3 package, 1.2 µA max quiescent current | Higher trip point unsuitable for 5 V systems requiring margin below 4.35 V; lower IQ benefits battery-powered designs | Select only if 4.63 V threshold aligns with system brown-out specification and SOT-23 footprint is preferred |
| TPS3808G12DBVR | 4.38 V threshold (±0.5%), adjustable delay option, 1.1 µA IQ, SOT-23-5 | Requires external capacitor for delay tuning; 5-pin package increases layout complexity vs. 3-pin SC70 | Choose when tighter threshold tolerance (±0.5%) or programmable timeout is mandatory, accepting extra pin count |
Compared with MAX809TRD2T and TPS3808G12DBVR, ADM1810-10AKSZ-RL7 offers optimal balance of 4.35 V trip point accuracy, SC70 space efficiency, and direct push-pull drive - making it ideal for cost-sensitive, high-volume 5 V microcontroller reset applications where fixed 150 ms timing suffices.

FAQ
What is the exact reset threshold voltage of ADM1810-10AKSZ-RL7 and its tolerance over temperature?
The ADM1810-10AKSZ-RL7 has a nominal reset threshold of 4.35 V (typical), with a minimum of 4.25 V and maximum of 4.49 V across −40°C to +105°C. This ±1.5% tolerance ensures consistent brown-out detection in automotive and industrial applications without requiring system-level calibration.
Does ADM1810-10AKSZ-RL7 require an external pull-up resistor on its RST pin?
No, ADM1810-10AKSZ-RL7 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 per datasheet Figure 13.
Can ADM1810-10AKSZ-RL7 be used to monitor 3.3 V or 2.5 V supplies?
No, ADM1810-10AKSZ-RL7 is specifically configured for 5 V supply monitoring with a 4.35 V trip point. For 3.3 V or 2.5 V rails, Analog Devices recommends ADM1815-10AKSZ-RL7 (2.88 V) or ADM1815-20AKSZ-RL7 (2.55 V), which belong to the same family but feature different internal reference trimming.
What is the reset timeout duration of ADM1810-10AKSZ-RL7 and is it adjustable?
The ADM1810-10AKSZ-RL7 provides a fixed 150 ms (typical) reset timeout after VCC rises above the threshold. This delay is internally generated and non-adjustable - ensuring predictable, repeatable system initialization timing without external components or configuration registers.
Is ADM1810-10AKSZ-RL7 compatible with lead-free reflow soldering processes?
Yes, ADM1810-10AKSZ-RL7 is RoHS-compliant (indicated by the "Z" suffix) and qualified for standard lead-free reflow profiles, including peak temperatures up to 260°C for 10 seconds. Its SC70 package meets JEDEC J-STD-020 moisture sensitivity level 1 requirements.
