Product details
Overview
ADM1810-5AKSZ-RL7 from Analog Devices is a precision active-low microprocessor reset circuit in SC70-3 package, monitoring 5 V supplies with 4.62 V typical trip threshold, 150 ms reset timeout, and push-pull output. It ensures safe system initialization in embedded controllers and industrial microprocessor systems where supply stabilization must precede reset release.
For engineers reviewing the ADM1810-5AKSZ-RL7 datasheet, ADM1810-5AKSZ-RL7 pinout, ADM1810-5AKSZ-RL7 application, or ADM1810-5AKSZ-RL7 equivalent, key selection factors include its guaranteed 4.50–4.75 V reset threshold range, −40°C to +105°C operating temperature, and compatibility with standard microprocessor reset inputs without external components.
Technical Context
The ADM1810-5AKSZ-RL7 implements a precision voltage comparator with internal reference and fixed 150 ms power-up delay timer. Its active-low push-pull output drives directly into most µP reset pins, eliminating need for pull-up resistors or level-shifting circuitry.
It operates across full 1.2–5.5 V supply range while consuming only 4–10 µA at 3.6 V, enabling use in low-power systems. The device asserts reset when VCC falls below its 4.62 V nominal threshold and holds reset active for ≥100 ms after VCC rises above threshold.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.50 V (min) to 4.75 V (max) - guarantees reliable detection of 5 V rail collapse before system corruption |
| Reset Timeout | 100–250 ms - provides sufficient margin for power supply stabilization prior to processor release |
| Supply Range | 1.2 V to 5.5 V - supports operation from battery-backed rails up to main 5 V supply |
| Quiescent Current | 4 µA at 3.6 V - enables integration into always-on monitoring paths without significant power penalty |
| Operating Temp | −40°C to +105°C - qualified for automotive under-hood and industrial control environments |
| Output Type | Active-low push-pull - delivers clean, rail-to-rail reset signal compatible with Intel/ARM reset inputs |
Pinout & Package
ADM1810-5AKSZ-RL7 uses the 3-lead SC70 (KS-3) package, measuring 2.00 mm × 2.10 mm × 0.95 mm with 0.65 mm lead pitch and JEDEC-compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST | Active-low reset output | Drives low during undervoltage condition and remains low for ≥100 ms after VCC recovery - directly interfaces µP reset pin |
| VCC | Supply voltage input | Monitored rail input; also powers internal circuitry - accepts 1.2–5.5 V, enabling self-powered monitoring |
| GND | Ground reference | 0 V return path for both supply and reset output - requires low-impedance connection to system ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Precision reset threshold | ±1.3% tolerance over temperature - eliminates need for external trimming in production systems |
| Fixed 150 ms reset timeout | Guaranteed minimum 100 ms hold time - ensures stable power before processor exit from reset |
| Low quiescent current | 4 µA at 3.6 V - reduces standby power in battery-critical applications |
| SC70-3 package | 2.0 × 2.1 mm footprint - saves PCB area vs. SOT-23 while maintaining reflow compatibility |
| Industrial temp grade | −40°C to +105°C operation - supports deployment in motor drives, PLCs, and automotive ECUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809SEUR+T | 4.63 V nominal threshold, 140 ms min reset timeout, SOT-23-3 package | Lacks SC70 option; higher 15 µA quiescent current at 3.6 V | Choose when SOT-23 footprint is preferred and 10 µA extra supply current is acceptable |
| TPS3808G01DBVR | 4.63 V threshold, adjustable timeout (1.25 ms to 10 s), 1.5 µA quiescent current | Requires external capacitor for timing; more complex layout and calibration | Choose when programmable reset duration is required for multi-rail sequencing |
Compared with MAX809SEUR+T and TPS3808G01DBVR, the ADM1810-5AKSZ-RL7 offers tighter threshold accuracy (±1.3% vs ±2%), lower operating current at 3.6 V (4 µA vs 15 µA), and SC70 packaging for space-constrained designs - making it optimal for high-reliability, compact industrial controllers.

FAQ
What is the exact reset threshold voltage range for ADM1810-5AKSZ-RL7?
The ADM1810-5AKSZ-RL7 has a guaranteed reset threshold range of 4.50 V (minimum) to 4.75 V (maximum) at −40°C to +105°C, with 4.62 V typical. This range ensures reliable detection of 5 V supply faults while rejecting noise-induced false triggers, and is validated per Analog Devices Rev. F datasheet Table 1.
Does ADM1810-5AKSZ-RL7 require external components to interface with a microprocessor reset input?
No, ADM1810-5AKSZ-RL7 does not require external components. Its active-low push-pull output drives directly into standard microprocessor reset pins, eliminating the need for pull-up resistors, capacitors, or level shifters - as confirmed in Figure 13 and General Description section of the ADM1810–ADM1818 datasheet.
What package type and dimensions does ADM1810-5AKSZ-RL7 use?
ADM1810-5AKSZ-RL7 uses the SC70-3 (KS-3) package: 2.00 mm × 2.10 mm × 0.95 mm body size with 0.65 mm lead pitch. Dimensions comply with EIAJ SC70 standards and are specified in Figure 16 of the Rev. F datasheet.
Can ADM1810-5AKSZ-RL7 be used in automotive applications?
Yes, ADM1810-5AKSZ-RL7 is qualified for −40°C to +105°C operation and is used in automotive body control modules per its Applications section. It meets the temperature and reliability requirements for non-safety-critical automotive subsystems, though it is not AEC-Q200 certified.
What is the reset timeout behavior of ADM1810-5AKSZ-RL7 during power-up?
During power-up, ADM1810-5AKSZ-RL7 asserts reset (RST = low) until VCC exceeds its threshold, then holds reset active for 100–250 ms - with 150 ms typical - before releasing. This ensures the 5 V supply stabilizes before the microprocessor exits reset, as defined in Table 1 and Figure 10 of the datasheet.
