Product details
Overview
ADM1815-5ARTZ-RL7 from Analog Devices is an active-low push-pull microprocessor reset circuit designed to monitor 3.06 V supply rails in embedded systems. It provides a 150 ms reset timeout after power-up, sinks up to 8 mA at 0.4 V, draws only 9–16 µA quiescent current, and operates across −40°C to +105°C for industrial-grade reliability in microcontroller-based instrumentation.
For engineers reviewing the ADM1815-5ARTZ-RL7 datasheet, ADM1815-5ARTZ-RL7 pinout, ADM1815-5ARTZ-RL7 application, or ADM1815-5ARTZ-RL7 equivalent, this device serves as a precision voltage supervisor for 3.3 V system initialization where deterministic reset timing and low-power operation are critical.
Technical Context
The ADM1815-5ARTZ-RL7 integrates a precision bandgap reference, comparator with hysteresis, and a 150 ms internal reset timer. Its trip point is fixed at 3.06 V (typical), with ±1.5% tolerance over temperature and supply range.
This variant belongs to the ADM1815 series-active-low push-pull output version of the ADM181x family-and is functionally identical to ADM1815-5ARTZ-REEL but supplied in 7-inch tape-and-reel packaging (RL7). It requires no external components for basic reset assertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.06 V typical (2.98–3.15 V min/max); monitors 3.3 V supplies with margin for ripple and drift. |
| Reset Timeout | 150 ms typical (100–250 ms); ensures stable power-up before releasing microprocessor reset line. |
| Supply Range | 1.2 V to 5.5 V; supports operation down to 1.2 V while monitoring higher rails via internal scaling. |
| Quiescent Current | 9–16 µA at 5.5 V; enables battery-backed or ultra-low-power system supervision. |
| Output Type | Active-low push-pull; drives MCU reset inputs directly without pull-up resistor or level-shifting. |
| Operating Temp | −40°C to +105°C; qualified for industrial and automotive under-hood applications. |
| Package | SOT-23 (RT-3); 3-pin, 2.9 mm × 1.3 mm footprint compatible with high-density PCB layouts. |
Pinout & Package
ADM1815-5ARTZ-RL7 is housed in a 3-lead SOT-23 (RT-3) package per JEDEC TO-236-AB, with 0.95 mm nominal height and coplanarity ≤0.10 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | RST | Active-low push-pull reset output; held low during undervoltage and for 150 ms after VCC exceeds threshold. |
| 2 | VCC | Supply input and monitored rail; powers internal circuitry and sets reference for threshold detection. |
| 3 | GND | Ground reference for all analog and digital functions; must be connected to system common ground plane. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326T29D3+T | 2.93 V threshold, 140 ms timeout, SOT-23, active-low open-drain output with 5.5 kΩ internal pull-up. | Requires external pull-up for push-pull behavior; less precise trip point (±2.5%) and narrower temp range (−40°C to +85°C). | Select when open-drain flexibility is needed for wired-OR reset buses or multi-source reset arbitration. |
| TPS3808G30DBVR | 3.0 V threshold, 200 ms timeout, SOT-23, active-low push-pull, 1.4 µA quiescent current. | Lower supply current but tighter 2.5% threshold tolerance and no industrial temp grade (−40°C to +125°C not validated). | Prefer for ultra-low-power battery systems where 200 ms timeout aligns with host MCU requirements. |
Compared with MAX6326T29D3+T and TPS3808G30DBVR, ADM1815-5ARTZ-RL7 delivers tighter threshold accuracy (±1.5%), guaranteed 150 ms timing, and full industrial temperature qualification-making it optimal for deterministic reset in mission-critical embedded controllers.

FAQ
What is the exact reset threshold voltage of ADM1815-5ARTZ-RL7?
The ADM1815-5ARTZ-RL7 has a nominal reset threshold of 3.06 V, with a guaranteed range of 2.98 V (min) to 3.15 V (max) over −40°C to +105°C. This value is factory-trimmed and specified in Table 1 of the Rev. F datasheet, making ADM1815-5ARTZ-RL7 suitable for monitoring 3.3 V supplies with adequate noise margin.
Does ADM1815-5ARTZ-RL7 require external components to operate?
No, ADM1815-5ARTZ-RL7 operates autonomously with only VCC, GND, and RST connections. Its active-low push-pull output drives most microprocessor reset inputs directly-no external pull-up resistor, capacitor, or timing network is needed. The internal 150 ms reset timeout and precision reference are fully integrated, simplifying design and reducing BOM cost.
What package type and footprint does ADM1815-5ARTZ-RL7 use?
ADM1815-5ARTZ-RL7 uses the 3-lead SOT-23 (RT-3) package per JEDEC TO-236-AB, with dimensions 2.90 mm × 1.30 mm × 1.02 mm. Pin 1 is RST (active-low output), Pin 2 is VCC (monitored supply), and Pin 3 is GND. This compact footprint supports high-density PCB layouts in space-constrained applications.
How does ADM1815-5ARTZ-RL7 behave during power-up and power-down events?
During power-up, ADM1815-5ARTZ-RL7 holds RST low until VCC rises above 3.06 V and remains low for 150 ms (typical) to ensure stable supply. During power-down, RST goes low within 10 µs of VCC falling below the threshold. This asymmetric timing guarantees safe initialization and rapid fault response, as confirmed in Figures 9 and 10 of the ADM181x datasheet.
Is ADM1815-5ARTZ-RL7 RoHS compliant and halogen-free?
Yes, ADM1815-5ARTZ-RL7 is RoHS compliant (indicated by the "Z" suffix per Analog Devices ordering guide) and meets JEDEC JS709B halogen-free requirements. The device uses lead-free matte tin finish on terminals and complies with EU Directive 2011/65/EU and China RoHS II, verified in the official Analog Devices product change notice PCN-12-0117-00.
