Product details
Overview
ADM1813-10AKSZ-RL7 from Analog Devices is a 3-pin open-drain microprocessor reset circuit with internal pull-up resistor, designed for monitoring 5 V power supplies. It features a 4.35 V typical reset threshold, 150 ms reset timeout, −40°C to +105°C operating temperature range, and supports manual push-button reset initiation. It ensures safe system initialization in embedded controllers requiring reliable power-on reset sequencing.
For engineers reviewing the ADM1813-10AKSZ-RL7 datasheet, ADM1813-10AKSZ-RL7 pinout, ADM1813-10AKSZ-RL7 application, or ADM1813-10AKSZ-RL7 equivalent, key selection criteria include its open-drain output with integrated 5.5 kΩ pull-up, push-button reset compatibility, 4.35 V trip point tolerance, SC70 package footprint, and guaranteed 150 ms reset assertion after power-up.
Technical Context
The ADM1813-10AKSZ-RL7 implements a precision voltage comparator with hysteresis and an internal 150 ms delay timer to prevent premature release during supply ramp-up. Its open-drain RST output with integrated 5.5 kΩ pull-up resistor enables direct connection to microprocessor reset inputs without external components.
It supports manual reset via push-button between RST and GND, with sub-microsecond detection and guaranteed 150 ms low pulse after button release. The device operates across the full industrial temperature range and draws only 4–10 µA quiescent current at 3.6 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 4.35 V typical (min 4.25 V, max 4.49 V) - precisely monitors 5 V rails with margin for ripple and drift |
| Reset Timeout | 150 ms typical (100–250 ms) - ensures stable power supply before releasing reset to CPU |
| Supply Range | 1.2 V to 5.5 V - supports operation even during brown-out conditions down to 1.2 V |
| Quiescent Current | 4 µA at 3.6 V - ultra-low power consumption ideal for battery-backed or energy-sensitive systems |
| Output Type | Open-drain with 5.5 kΩ internal pull-up - eliminates need for external resistor; compatible with 1.8–5.5 V logic interfaces |
| Push-Button Response | 1 µs detect time, 150 ms asserted reset - enables robust manual reset with debounced timing |
| Operating Temp | −40°C to +105°C - qualified for automotive, industrial, and harsh-environment applications |
Pinout & Package
ADM1813-10AKSZ-RL7 is housed in a 3-lead SC70 (KS-3) package, measuring 2.00 mm × 2.10 mm × 0.95 mm, with JEDEC-compliant footprint and coplanarity ≤0.10 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST | Active-low open-drain reset output | Drives low when VCC < threshold; floats high (pulled up internally) otherwise; supports wired-OR and multi-source reset arbitration |
| VCC | Supply voltage input | Monitored rail input; also powers internal circuitry; valid from 1.2 V to 5.5 V |
| GND | Ground reference | 0 V return path for all internal functions and reset output sink current |
Key Features
| Feature | Design Value |
|---|---|
| Integrated pull-up resistor | 5.5 kΩ nominal - eliminates external component, reduces BOM count and PCB area |
| Push-button reset support | Detects <1 µs button press and asserts 150 ms reset - enables field service and recovery without firmware intervention |
| Guaranteed reset timeout | 100–250 ms range over temperature - ensures deterministic startup timing across environmental extremes |
| Low supply current | 4 µA at 3.6 V - extends battery life in always-on or backup-power systems |
| Wide supply range | 1.2 V to 5.5 V operation - maintains functionality during undervoltage events and partial power loss |
Applications
| Industrial PLC Controller | Automotive Body Control Module |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage monitor and reset generator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809SEUR+T | 4.63 V fixed threshold; SOT-23-3; no internal pull-up; requires external resistor | Lacks push-button reset support; higher threshold unsuitable for 4.35 V margin-critical designs | Select when 4.63 V trip point aligns with system tolerance and board space allows external pull-up |
| TPS3808G12DBVR | Adjustable threshold (via resistor divider); 1.2–5.8 V range; 200 ms default timeout; 1.5 µA IQ | Higher complexity, programmability, and cost; over-specified for fixed 4.35 V monitoring | Choose only if design requires configurable trip point or extended timeout beyond 150 ms |
Compared with MAX809SEUR+T and TPS3808G12DBVR, the ADM1813-10AKSZ-RL7 delivers optimized simplicity for 5 V systems: its factory-trimmed 4.35 V threshold, integrated pull-up, and push-button capability reduce component count and validation effort while meeting stringent industrial timing requirements.

FAQ
What is the exact reset threshold voltage for ADM1813-10AKSZ-RL7?
The ADM1813-10AKSZ-RL7 has a guaranteed reset threshold of 4.25 V (minimum), 4.35 V (typical), and 4.49 V (maximum) at −40°C to +105°C. This 4.35 V typical value is factory-trimmed and specified for monitoring standard 5 V power supplies with adequate noise margin.
Does ADM1813-10AKSZ-RL7 require an external pull-up resistor on the RST pin?
No. The ADM1813-10AKSZ-RL7 integrates a 5.5 kΩ internal pull-up resistor on the RST pin, eliminating the need for external components. This simplifies PCB layout, reduces BOM count, and ensures consistent rise time without dependency on external resistor tolerances.
Can ADM1813-10AKSZ-RL7 be used with a manual push-button reset?
Yes. The ADM1813-10AKSZ-RL7 explicitly supports push-button reset: connecting a switch between RST and GND pulls the output low, and upon release, the device asserts a clean 150 ms reset pulse. This feature is confirmed in the datasheet's "ADM1813 AND ADM1818" section and timing diagram Figure 12.
What package type is used for ADM1813-10AKSZ-RL7?
The ADM1813-10AKSZ-RL7 uses the 3-lead SC70 (KS-3) package, measuring 2.00 mm × 2.10 mm × 0.95 mm. It is RoHS-compliant (indicated by the "Z" suffix) and JEDEC-compliant per EIAJ SC70 standards.
What is the supply current consumption of ADM1813-10AKSZ-RL7 at 3.6 V?
At 3.6 V supply and TA = −40°C to +105°C, the ADM1813-10AKSZ-RL7 consumes 4 µA (minimum) to 10 µA (maximum) quiescent current when VCC > VTH and no load is applied - enabling ultra-low-power operation in battery-backed or energy-harvesting systems.
