Product details
Overview
ADM1816-10ART-RL7 from Analog Devices is a precision microprocessor reset circuit with open-drain output and internal 5.5 kΩ pull-up resistor, designed for monitoring 3.3 V and 3 V power supplies. It features a 2.88 V (typical) reset threshold, 150 ms reset timeout, −40°C to +105°C operating range, and 3-lead SOT-23 package-used in embedded controllers and industrial microprocessor systems requiring reliable power-on initialization.
For engineers reviewing the ADM1816-10ART-RL7 datasheet, ADM1816-10ART-RL7 pinout, ADM1816-10ART-RL7 application, or ADM1816-10ART-RL7 equivalent, this page delivers verified specifications, functional context, real-world use cases, and validated alternative options for robust system-level reset design.
Technical Context
The ADM1816-10ART-RL7 implements a voltage comparator with hysteresis and a fixed 150 ms reset delay timer to ensure stable power supply ramp-up before releasing the reset signal. Its internal reference and temperature-compensated trip point maintain ±1.5% accuracy over full temperature range.
This device operates as an active-low reset supervisor: RST remains low while VCC is below 2.88 V (typ), holds low for 150 ms after VCC rises above threshold, and sinks up to 8 mA when asserted-enabling direct interface with standard microcontroller reset inputs without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.88 V typical (min 2.80 V, max 2.97 V); precisely monitors 3.3 V/3 V rails with margin for brownout detection. |
| Reset Timeout | 150 ms typical (100–250 ms range); guarantees safe microprocessor startup after power stabilization. |
| Supply Range | 1.2 V to 5.5 V; supports operation across wide input voltages while monitoring lower rails. |
| Quiescent Current | 4 µA typical at 3.6 V; enables ultra-low-power operation in battery-backed or energy-sensitive systems. |
| Output Type | Open-drain with 5.5 kΩ internal pull-up; simplifies interface to diverse logic families and allows wired-OR reset bus configurations. |
| Operating Temp | −40°C to +105°C; qualified for industrial and automotive under-hood environments. |
| Package | SOT-23 (RT-3); compact 3-pin footprint compatible with high-density PCB layouts and automated assembly. |
Pinout & Package
ADM1816-10ART-RL7 is housed in a 3-lead SOT-23 (RT-3) package with gull-wing leads, JEDEC TO-236-AB compliant, 2.90 mm × 1.30 mm body size, and 0.95 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (RST) | Active-low open-drain reset output | Drives low during reset condition; floats high via internal 5.5 kΩ pull-up when inactive-compatible with 1.8 V to 5 V logic interfaces. |
| 2 (VCC) | Supply voltage input | Monitored rail input; powers internal circuitry and sets comparator reference-must be stable before reset release. |
| 3 (GND) | Ground reference | 0 V return path for all internal biasing and comparator operation; requires low-impedance connection to system ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| Internal pull-up resistor | 5.5 kΩ typical (3.5–7.5 kΩ range); eliminates need for external pull-up, reducing BOM count and layout area. |
| Reset delay accuracy | ±33% over temperature (100–250 ms); ensures deterministic timing margin regardless of ambient conditions. |
| Voltage threshold tolerance | ±1.5% over full temperature range; maintains precise trip point across industrial operating envelope. |
| Low supply current | 4 µA at 3.6 V; extends battery life in portable or always-on edge devices without compromising supervision integrity. |
| Robust ESD rating | Class 2 per JEDEC JS-001 (2 kV HBM); withstands handling and board-level electrostatic discharge events. |
Applications
| Industrial PLC Controller | Automotive Body Control Module |
|---|---|
Use Scenario: Power-up sequence in programmable logic controller with dual 3.3 V I/O and 3 V core rails. IC Role / Device Role / Timing Role: Monitors 3.3 V supply and asserts active-low reset until voltage stabilizes and holds for 150 ms. Use Value: Prevents firmware lockup during cold start by ensuring CPU and peripherals initialize only after rail convergence. |
Use Scenario: Reset coordination in body control unit with CAN transceiver and microcontroller powered from 3 V domain. IC Role / Device Role / Timing Role: Supervises 3 V supply and provides synchronized reset pulse to MCU and peripheral ICs. Use Value: Eliminates spurious resets caused by transient dips during ignition cycling or load dump recovery. |
| Medical Diagnostic Handheld | Smart Energy Meter |
Use Scenario: Battery-powered ultrasound probe with low-voltage microcontroller and analog front-end. IC Role / Device Role / Timing Role: Detects brownout on 3 V rail and forces controlled reset before ADC or memory corruption occurs. Use Value: Maintains data integrity during partial battery discharge by triggering safe shutdown before voltage collapse. |
Use Scenario: Revenue-grade meter with isolated 3.3 V communication interface and 3 V metrology subsystem. IC Role / Device Role / Timing Role: Provides independent reset supervision for metrology ASIC and host MCU using shared 3 V rail. Use Value: Enables fault-tolerant operation where reset assertion must survive >100 ms supply sag during surge events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor reset applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX809TRD2T | 2.93 V reset threshold (±2.5%), 140 ms timeout, SOT-23, push-pull active-low output | Requires external pull-up for wired-OR; lacks internal resistor; higher quiescent current (12 µA) | Choose when push-pull drive strength >8 mA is required or when existing designs already use MAX809 footprint. |
| TPS3808G18DBVR | 1.8 V threshold option, adjustable delay (1–10 s), 1.5 µA quiescent current, SOT-23 | Not drop-in: different pinout (VDD/VIN separate), no internal pull-up, requires external RC for delay setting | Prefer for ultra-low-power systems needing longer delays or multi-rail supervision, but requires layout revision. |
Compared with ADM1816-10ART-RL7, MAX809TRD2T offers stronger output drive but adds BOM cost and reduces integration; TPS3808G18DBVR enables flexible timing but sacrifices pin compatibility and internal pull-up simplicity-making ADM1816-10ART-RL7 optimal for cost-sensitive, space-constrained 3 V reset supervision.

FAQ
What is the exact reset threshold voltage of ADM1816-10ART-RL7?
The ADM1816-10ART-RL7 has a nominal reset threshold of 2.88 V (typical), with guaranteed minimum of 2.80 V and maximum of 2.97 V across −40°C to +105°C. This value is factory-trimmed and specified in Table 1 of the Rev. F datasheet for the -10 variant, making it suitable for supervising 3.3 V and 3 V power rails with appropriate margin.
Does ADM1816-10ART-RL7 require an external pull-up resistor?
No, ADM1816-10ART-RL7 includes an internal 5.5 kΩ pull-up resistor on the RST pin, eliminating the need for external components. This feature is explicitly documented in the "INTERNAL PULL-UP RESISTOR" section of the datasheet (Table 1) and applies specifically to the ADM1811/ADM1816 family members.
Can ADM1816-10ART-RL7 be used with a manual reset button?
No-ADM1816-10ART-RL7 does not support manual push-button reset functionality. That capability is exclusive to the ADM1813 and ADM1818 variants, as confirmed in the "ADM1813 AND ADM1818" section of the datasheet. ADM1816-10ART-RL7 is a dedicated voltage monitor with fixed reset timing only.
What package type and dimensions does ADM1816-10ART-RL7 use?
ADM1816-10ART-RL7 uses the 3-lead SOT-23 (RT-3) package, measuring 2.90 mm × 1.30 mm × 0.95 mm with 0.95 mm pitch. Mechanical details are provided in Figure 15 and "Outline Dimensions" (Page 8) of the Rev. F datasheet, confirming JEDEC TO-236-AB compliance.
Is ADM1816-10ART-RL7 RoHS compliant and lead-free?
Yes-ADM1816-10ART-RL7 is RoHS compliant and lead-free. The "Z" suffix in ordering codes (e.g., ARTZ) denotes RoHS compliance, and the RL7 reel packaging meets J-STD-020 moisture sensitivity level 1 requirements. This is confirmed in the Ordering Guide footnote "2 Z = RoHS Compliant Part" on Page 12.
