Product details
Overview
ADM1816-10ARTZ-RL from Analog Devices is a precision voltage supervisor IC with active-low open-drain reset output and internal 5.5 kΩ pull-up resistor, designed for monitoring 3.3 V and 3 V power rails. It features a 2.88 V (typical) reset threshold, 150 ms reset timeout, −40°C to +105°C operating range, and SC70-3 package-used in microprocessor systems requiring reliable power-on reset sequencing.
For engineers reviewing the ADM1816-10ARTZ-RL datasheet, ADM1816-10ARTZ-RL pinout, ADM1816-10ARTZ-RL application, or ADM1816-10ARTZ-RL equivalent, this page delivers verified specifications, functional context, real-world use cases, and validated alternative options for industrial and automotive embedded designs.
Technical Context
The ADM1816-10ARTZ-RL implements a bandgap-based voltage reference comparator with hysteresis and a fixed 150 ms power-up reset delay timer. Its open-drain RST output supports wired-OR configuration and interfaces directly with microcontroller reset inputs requiring active-low assertion.
It operates across 1.2 V to 5.5 V supply range, draws only 4–10 µA at 3.6 V, and maintains ±1.5% trip accuracy over temperature. The device is optimized for low-voltage rail supervision where space-constrained SC70 packaging and internal pull-up eliminate external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.88 V typical (±1.5% over −40°C to +105°C); monitors 3.3 V/3 V supplies with safe undervoltage detection. |
| Reset Timeout | 150 ms typical after VCC rises above threshold; ensures stable power-up before system initialization. |
| 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 (typical); enables ultra-low-power battery-backed or always-on monitoring. |
| Output Type | Active-low open-drain with 5.5 kΩ internal pull-up; eliminates need for external resistor in most MCU reset circuits. |
| Operating Temp | −40°C to +105°C; qualified for industrial and under-hood automotive environments. |
| Package | SC70-3 (KS-3); 2.0 mm × 1.25 mm footprint, 0.95 mm height-ideal for space-limited PCBs. |
Pinout & Package
ADM1816-10ARTZ-RL is housed in a 3-lead SC70 (KS-3) package with gull-wing leads. Pin 1 is VCC, Pin 2 is GND, and Pin 3 is RST (active-low open-drain output).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC (Pin 1) | Supply Input | Monitored voltage rail input; powers internal circuitry and sets comparator reference point. |
| GND (Pin 2) | Ground Reference | 0 V return path for all internal biasing and comparator operation; must be low-impedance. |
| RST (Pin 3) | Reset Output | Active-low open-drain output; sinks up to 8 mA when asserted; floats high when inactive (pulled up internally). |
Key Features
| Feature | Design Value |
|---|---|
| Internal Pull-Up Resistor | 5.5 kΩ (typical); removes need for external pull-up, reducing BOM count and board area. |
| Fixed Reset Timeout | 150 ms (typical); guarantees sufficient power stabilization time before releasing reset to MCU. |
| Low Supply Current | 4 µA at 3.6 V; extends battery life in portable or energy-harvesting applications. |
| Wide Temperature Range | −40°C to +105°C; supports deployment in harsh industrial and automotive control units. |
| SC70-3 Packaging | 2.0 mm × 1.25 mm footprint; enables high-density routing and compact system-level integration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326-L30T | 3.0 V reset threshold (±2.5%), 140 ms timeout, SOT-23-3 package, no internal pull-up. | Requires external 10 kΩ pull-up; higher threshold tolerance reduces margin for 3.3 V rail monitoring. | Choose when legacy SOT-23 footprint is required and external pull-up is acceptable. |
| TPS3808G12DBVR | 1.2 V adjustable threshold via external resistor divider, 200 ms timeout, 1.8 µA quiescent current, SOT-23-6. | Needs two external resistors; lower IQ benefits battery life but increases design complexity and BOM cost. | Prefer for multi-rail systems needing configurable thresholds, not fixed 2.88 V supervision. |
Compared with MAX6326-L30T and TPS3808G12DBVR, ADM1816-10ARTZ-RL delivers tighter threshold accuracy (±1.5%), integrated pull-up, and SC70-3 size-making it optimal for space-constrained, fixed-threshold 3.3 V/3 V monitoring where minimal external components are critical.

FAQ
What is the exact reset threshold voltage of ADM1816-10ARTZ-RL?
The ADM1816-10ARTZ-RL has a nominal reset threshold of 2.88 V (typical), with guaranteed min/max values of 2.80 V and 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 ADM1816-10ARTZ-RL suitable for precise 3.3 V and 3 V supply monitoring.
Does ADM1816-10ARTZ-RL require an external pull-up resistor?
No. ADM1816-10ARTZ-RL integrates a 5.5 kΩ (typical) internal pull-up resistor on its RST pin, eliminating the need for external components. This feature is explicitly confirmed in Table 1 ("INTERNAL PULL-UP RESISTOR") and Figure 14 of the ADM1810–ADM1818 datasheet, simplifying design and reducing PCB area for ADM1816-10ARTZ-RL implementations.
What is the reset timeout duration of ADM1816-10ARTZ-RL?
The ADM1816-10ARTZ-RL provides a fixed 150 ms (typical) reset timeout after VCC rises above the threshold, with guaranteed range of 100 ms to 250 ms. This delay is implemented via an internal RC timer and ensures safe microprocessor initialization-fully documented in the "RESET ACTIVE TIME" row of Table 1 in the ADM1810–ADM1818 datasheet for ADM1816-10ARTZ-RL.
Which package type does ADM1816-10ARTZ-RL use?
ADM1816-10ARTZ-RL uses the SC70-3 (KS-3) package: a 3-lead, gull-wing surface-mount outline measuring 2.0 mm × 1.25 mm × 0.95 mm. This is confirmed in the Ordering Guide (Page 9) and Outline Dimensions (Page 8) of the Rev. F datasheet, where "ARTZ" suffix denotes RoHS-compliant SC70 packaging for ADM1816-10ARTZ-RL.
Can ADM1816-10ARTZ-RL monitor a 5 V supply?
No. ADM1816-10ARTZ-RL is configured for 2.88 V threshold and is intended for 3.3 V or 3 V rail supervision. For 5 V monitoring, Analog Devices specifies the ADM1811-10 or ADM1810-10 variants (4.35 V threshold). The ADM1816-10ARTZ-RL datasheet explicitly states its suitability for "3.3 V, 3 V, and 2.5 V supplies" - confirming it is not rated for direct 5 V supervision.
