Product details
Overview
ADM1815-10AKS-RL7 from Analog Devices is an active-low push-pull microprocessor reset circuit in SC70-3 package, monitoring 3.3 V supplies with a 2.88 V (typical) reset threshold, 150 ms reset timeout, and −40°C to +105°C operating range. It ensures safe system initialization in embedded controllers and industrial microprocessor systems by holding reset until power stabilizes.
For engineers reviewing the ADM1815-10AKS-RL7 datasheet, ADM1815-10AKS-RL7 pinout, ADM1815-10AKS-RL7 application, or ADM1815-10AKS-RL7 equivalent, key selection criteria include trip point accuracy (±1.5% typical), low quiescent current (4–10 µA at 3.6 V), push-pull output drive capability (350 µA source / 8 mA sink), and SC70 footprint compatibility for space-constrained designs.
Technical Context
The ADM1815-10AKS-RL7 implements a precision voltage comparator with internal reference and fixed 150 ms reset delay timer. Its active-low push-pull output directly interfaces with standard microprocessor reset inputs without external pull-up components.
It operates across 1.2 V to 5.5 V supply range, delivers guaranteed reset assertion during power-up and power-down transients, and maintains trip point stability over temperature (±0.5% drift from −40°C to +105°C per Figure 7).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.88 V typical (2.80–2.97 V min/max); monitors 3.3 V supply rails with margin for ripple and tolerance. |
| Reset Timeout | 150 ms typical (100–250 ms min/max); ensures sufficient power stabilization before release of processor reset. |
| Supply Range | 1.2 V to 5.5 V; supports wide input voltage operation including battery-backed and multi-rail systems. |
| Quiescent Current | 4 µA typical at 3.6 V; enables ultra-low-power operation in always-on monitoring applications. |
| Output Type | Active-low push-pull; drives reset line directly-no external resistor required for MCU interface. |
| Operating Temp | −40°C to +105°C; qualified for industrial and automotive under-hood environments. |
| Package | SC70-3 (KS-3); 2.0 mm × 1.25 mm footprint, 0.95 mm height-suitable for high-density PCB layouts. |
Pinout & Package
ADM1815-10AKS-RL7 uses a 3-lead SC70 package (JEDEC KS-3). Pin 1 = RST (active-low reset output), Pin 2 = VCC (monitored supply input), Pin 3 = GND (ground reference).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST | Active-low reset output | Drives low during undervoltage condition and for 150 ms after VCC rises above threshold; compatible with standard µP reset inputs. |
| VCC | Supply voltage input | Monitored rail-device draws current only from this pin; no separate bias supply required. |
| GND | Ground reference | 0 V return path for both comparator and output stage; must be connected to system ground plane for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Fixed 150 ms reset timeout | Guarantees stable power-up sequence without external timing components or firmware intervention. |
| Push-pull output architecture | Eliminates need for external pull-up resistor-reduces BOM count and layout area in reset signal path. |
| Low temperature drift | ±0.5% trip point variation over −40°C to +105°C enables reliable operation in harsh thermal environments. |
| Ultra-low supply current | 4 µA at 3.6 V allows continuous monitoring in battery-powered or energy-sensitive systems. |
| SC70-3 package | 0.65 mm pitch, 2.0 × 1.25 mm footprint-enables miniaturized designs where SOT-23 is too large. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADM1815-10ARTZ-RL7 | SOT-23-3 package (RT-3), same 2.88 V trip point and push-pull output. | Larger footprint (2.9 × 1.3 mm vs. 2.0 × 1.25 mm) and higher thermal impedance (270°C/W vs. 146°C/W). | Select when board layout requires SOT-23 compatibility or manual assembly is preferred. |
| TLV803EB28DBZR | Texas Instruments part with 2.83 V threshold, open-drain output, and 140 ms timeout; requires external pull-up. | Lower supply current (0.5 µA) but lacks push-pull drive-adds component count and noise sensitivity. | Choose for ultra-low-power applications where external pull-up is acceptable and tighter trip tolerance (±0.5%) is critical. |
Compared with ADM1815-10ARTZ-RL7, the ADM1815-10AKS-RL7 saves 38% board area and improves thermal performance; versus TLV803EB28DBZR, it eliminates external components and simplifies layout but consumes slightly more quiescent current.

FAQ
What is the exact reset threshold voltage of the ADM1815-10AKS-RL7?
The ADM1815-10AKS-RL7 has a nominal reset threshold of 2.88 V (typical), with guaranteed minimum and maximum values of 2.80 V and 2.97 V respectively across −40°C to +105°C. This value is factory-trimmed and specified in Table 1 of the Rev. F datasheet, making ADM1815-10AKS-RL7 suitable for reliable supervision of 3.3 V supply rails.
Does the ADM1815-10AKS-RL7 require an external pull-up resistor on its RST pin?
No, the ADM1815-10AKS-RL7 features an active-low push-pull output stage, so it does not require an external pull-up resistor. The RST pin actively drives low during reset and high when released, enabling direct connection to most microprocessor reset inputs. This design eliminates one passive component and reduces layout complexity compared to open-drain alternatives like ADM1816-10AKSZ-RL7.
What is the reset timeout duration of the ADM1815-10AKS-RL7 and how is it implemented?
The ADM1815-10AKS-RL7 provides a fixed 150 ms (typical) reset timeout, with a guaranteed range of 100 ms to 250 ms. This delay is generated by an internal RC timer and begins when VCC rises above the reset threshold. It ensures the monitored power rail remains stable before releasing the reset signal-critical for safe microprocessor initialization. No external capacitor or configuration is needed; the timing is fully integrated within ADM1815-10AKS-RL7.
Can the ADM1815-10AKS-RL7 be used to monitor a 5 V supply?
No, the ADM1815-10AKS-RL7 is configured for 2.88 V threshold and optimized for 3.3 V supply monitoring. For 5 V applications, Analog Devices specifies the ADM1810-10AKS-RL7 (4.35 V threshold) or ADM1810-5AKS-RL7 (4.62 V threshold). Using ADM1815-10AKS-RL7 on a 5 V rail would result in immediate and permanent reset assertion, rendering it nonfunctional for that voltage level.
Is the ADM1815-10AKS-RL7 RoHS compliant and what is its moisture sensitivity level?
Yes, the ADM1815-10AKS-RL7 is RoHS compliant (indicated by the "Z" suffix in ordering codes such as AKSZ), and it carries a Moisture Sensitivity Level (MSL) of 1-meaning it is not moisture sensitive and can be stored indefinitely at ambient conditions without baking prior to reflow. This simplifies manufacturing handling and eliminates MSL-related process constraints for ADM1815-10AKS-RL7.
