Product details
Overview
ADM1816-10AKS-RL7 from Analog Devices is a precision microprocessor reset circuit with active-low open-drain output and internal 5.5 kΩ pull-up resistor, designed to monitor 3.3 V or 3 V power supplies. It features a 2.88 V (typical) reset threshold, 150 ms reset timeout, −40°C to +105°C operating temperature range, and SC70-3 package. It ensures safe system initialization in embedded controllers and industrial microprocessor systems.
For engineers reviewing the ADM1816-10AKS-RL7 datasheet, ADM1816-10AKS-RL7 pinout, ADM1816-10AKS-RL7 application, or ADM1816-10AKS-RL7 equivalent, key selection criteria include reset threshold accuracy (±1.5% typical), low quiescent current (≤10 µA at 3.6 V), open-drain compatibility with I²C-bus logic levels, and guaranteed reset assertion during power ramp-up and brownout conditions.
Technical Context
The ADM1816-10AKS-RL7 implements a bandgap-based voltage reference with comparator hysteresis and a precision timing circuit that guarantees ≥100 ms and ≤250 ms reset active time after VCC rises above threshold. Its internal 5.5 kΩ pull-up enables direct interface to standard CMOS inputs without external components.
It belongs to the ADM181x family of single-supply reset monitors optimized for space-constrained applications. Unlike push-pull variants, its open-drain output supports wired-OR configurations and mixed-voltage system resets, while maintaining full compatibility with 3.3 V and 2.5 V logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.88 V typical (min 2.80 V, max 2.97 V); precisely targets 3.3 V supply monitoring with margin for ripple and tolerance. |
| Reset Timeout | 150 ms typical (100–250 ms); ensures stable power rail before releasing microprocessor reset line. |
| Supply Range | 1.2 V to 5.5 V; operates correctly across full VCC range while monitoring only the designated rail. |
| Quiescent Current | ≤10 µA at 3.6 V; enables ultra-low-power operation in battery-backed or always-on systems. |
| Output Type | Active-low open-drain with 5.5 kΩ internal pull-up; eliminates need for external resistor and supports multi-drop reset buses. |
| Temperature Range | −40°C to +105°C; qualified for industrial and automotive under-hood environments. |
| Propagation Delay | 100 µs (rising edge), 10 µs (falling edge); fast response to supply faults while avoiding noise-induced false triggers. |
Pinout & Package
ADM1816-10AKS-RL7 is housed in a 3-lead SC70 (KS-3) package - 2.0 mm × 1.25 mm × 0.9 mm, JEDEC-compliant, RoHS-compliant, and moisture-sensitive level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (VCC) | Supply Input / Monitor Rail | Primary power rail being monitored; also powers internal circuitry; must be connected before reset assertion is valid. |
| 2 (GND) | Ground Reference | 0 V reference for all internal comparators and timing circuits; requires low-impedance connection to system ground plane. |
| 3 (RST) | Active-Low Open-Drain Reset Output | Sinks up to 8 mA when asserted; floats high via internal 5.5 kΩ pull-up when deasserted; compatible with 1.8 V–5 V logic inputs. |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed reset threshold | 2.88 V ±1.5% over temperature; eliminates need for external resistor divider calibration in production. |
| Guaranteed power-up reset | 150 ms minimum timeout after VCC exceeds threshold; prevents premature CPU execution before supply stabilization. |
| Low supply current | ≤10 µA at 3.6 V; reduces standby power in always-on subsystems such as watchdog supervisors or IoT edge nodes. |
| SC70-3 footprint | 2.0 mm × 1.25 mm area; saves >40% board space vs. SOT-23 while maintaining same pinout compatibility. |
| Open-drain with integrated pull-up | 5.5 kΩ internal resistor; removes BOM item and layout risk associated with external pull-up placement and value selection. |
Applications
| Industrial PLC Controller | Automotive Body Control Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326UT29D3+ | 2.93 V fixed threshold, 140 ms timeout, SOT-23-3 package, higher 20 µA supply current | Designed for telecom power sequencing; lacks internal pull-up, requires external resistor | Select when legacy SOT-23 footprint is mandatory and 2.93 V threshold better matches 3.3 V rail tolerance stack-up. |
| TPS3808G12DBVR | 1.225 V adjustable threshold (via external resistor), 200 ms timeout, 1.6 µA typical current, SOT-23-6 | Programmable trip point enables multi-rail monitoring; larger package and different pinout | Choose when flexibility across multiple supply voltages is needed and board space allows SOT-23-6; not drop-in compatible. |
Compared with MAX6326UT29D3+ and TPS3808G12DBVR, the ADM1816-10AKS-RL7 offers tighter threshold accuracy (±1.5% vs ±2.5%), lower quiescent current (≤10 µA vs 20 µA/1.6 µA), and integrated pull-up-reducing component count and layout complexity in fixed 2.88 V monitoring roles.

The ADM1816-10AKS-RL7 has a nominal reset threshold of 2.88 V, with a guaranteed range of 2.80 V (minimum) to 2.97 V (maximum) across −40°C to +105°C. This threshold is factory-trimmed and specified in Table 1 of the Rev. F datasheet, making it suitable for monitoring 3.3 V supplies with adequate margin for ripple and tolerance.
Does the ADM1816-10AKS-RL7 require an external pull-up resistor on the RST pin?
No, the ADM1816-10AKS-RL7 includes an internal 5.5 kΩ pull-up resistor on the RST pin, eliminating the need for an external component. This feature simplifies design, reduces BOM count, and ensures consistent rise time and logic-high level across temperature and voltage ranges.
Can the ADM1816-10AKS-RL7 be used to monitor a 5 V supply?
No-the ADM1816-10AKS-RL7 is specifically configured for 2.88 V threshold and is intended for 3.3 V or 3 V supply monitoring. For 5 V monitoring, Analog Devices offers the ADM1811-10AKSZ-RL7 (4.35 V threshold) or ADM1810-10AKS-RL7 (4.35 V, active-low push-pull).
What is the operating temperature range of the ADM1816-10AKS-RL7?
The ADM1816-10AKS-RL7 is rated for continuous operation from −40°C to +105°C, fully qualified per industrial temperature specifications. This range is confirmed in the Ordering Guide and Absolute Maximum Ratings tables of the Rev. F datasheet.
Is the ADM1816-10AKS-RL7 pin-compatible with other ADM181x devices in SC70-3 package?
Yes-ADM1816-10AKS-RL7 shares identical SC70-3 (KS-3) pinout (VCC, GND, RST) and footprint with all other ADM181x SC70 variants, including ADM1811, ADM1813, ADM1815, and ADM1818. However, reset thresholds and output types differ, so electrical compatibility must be verified per application.
