Product details
Overview
ADM1816-5ARTZ-REEL from Analog Devices is a precision 3.06 V (typical) open-drain microprocessor reset circuit with internal 5.5 kΩ pull-up resistor, 150 ms reset timeout, and −40°C to +105°C operating range in SOT-23 package. It monitors 3.3 V power rails in embedded controllers and ensures safe system initialization after power-on.
For engineers reviewing the ADM1816-5ARTZ-REEL datasheet, ADM1816-5ARTZ-REEL pinout, ADM1816-5ARTZ-REEL application, or ADM1816-5ARTZ-REEL equivalent, key selection criteria include trip point accuracy (±1.5% typical), low quiescent current (9–16 µA), open-drain output compatibility with I²C-bus logic levels, and industrial temperature support without external components.
Technical Context
The ADM1816-5ARTZ-REEL implements a bandgap-based voltage reference with comparator hysteresis and a fixed 150 ms power-up delay timer. Its reset assertion is triggered when VCC falls below 3.06 V (typical), with ±1.5% tolerance over temperature and supply variation.
It features an open-drain RST output with integrated 5.5 kΩ pull-up resistor (3.5–7.5 kΩ range), enabling direct connection to microcontroller reset inputs requiring active-low assertion and bus-compatible voltage levels. No external capacitor or resistor is needed for basic operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 3.06 V typical (2.98–3.15 V min/max); precisely monitors 3.3 V supplies with margin for ripple and droop |
| Reset Timeout | 150 ms typical (100–250 ms range); guarantees stable power before releasing reset to prevent premature boot |
| Supply Range | 1.2 V to 5.5 V; operates across wide input while monitoring only 3.3 V rail |
| Quiescent Current | 9–16 µA at 5.5 V; enables ultra-low-power system supervision in battery-backed applications |
| Output Type | Open-drain with 5.5 kΩ internal pull-up; eliminates need for external pull-up and supports wired-OR reset buses |
| Operating Temp | −40°C to +105°C; qualified for industrial and automotive under-hood environments |
| Package | SOT-23 (RT-3); 3-pin, 2.9 mm × 1.3 mm footprint compatible with high-density PCB layouts |
Pinout & Package
ADM1816-5ARTZ-REEL is housed in a 3-lead SOT-23 (RT-3) package with JEDEC TO-236-AB compliance, 2.9 mm × 1.3 mm body, and 0.95 mm height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RST | Active-low open-drain reset output | Drives low during reset; floats high via internal 5.5 kΩ pull-up when released - directly interfaces with most µP reset pins |
| VCC | Monitored supply input | Connects to 3.3 V rail being supervised; powers internal circuitry and defines threshold reference |
| GND | Ground reference | 0 V return path for all internal biasing and comparator operation; must be low-impedance for accurate threshold tracking |
Key Features
| Feature | Design Value |
|---|---|
| Factory-trimmed reset threshold | 3.06 V ±1.5% over temperature ensures reliable 3.3 V rail supervision without calibration |
| Integrated pull-up resistor | 5.5 kΩ (3.5–7.5 kΩ) eliminates external component count and reduces BOM cost |
| Fixed 150 ms reset timeout | Guarantees minimum power stabilization time before release - no external timing capacitor required |
| Low supply current | 9 µA min at 3.6 V enables use in always-on supervisory circuits without impacting system power budget |
| Industrial temperature grade | −40°C to +105°C operation supports deployment in harsh environments including motor control and factory automation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage supervisor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6326UT31D3+T | 3.08 V threshold, 200 ms timeout, 1.8–5.5 V supply, SC70-3 package | Higher timeout tolerance and wider supply range; lacks internal pull-up (requires external resistor) | Choose when longer reset hold time or broader input voltage operation is required, and board layout allows external pull-up |
| TPS3808G33DBVR | 3.3 V threshold, 200 ms timeout, push-pull output, SOT-23-6 package | Higher trip point targets 3.3 V nominal rail directly; push-pull eliminates need for pull-up but prevents wired-OR | Prefer when system requires active-high reset or shared reset bus is not used; note larger 6-pin footprint |
Compared with MAX6326UT31D3+T and TPS3808G33DBVR, the ADM1816-5ARTZ-REEL offers tighter threshold accuracy (±1.5% vs ±2.5%), lower quiescent current (9 µA vs 12–20 µA), and integrated pull-up - making it optimal for space- and power-constrained 3.3 V systems requiring wired-OR reset capability.

FAQ
What is the exact reset threshold voltage of the ADM1816-5ARTZ-REEL?
The ADM1816-5ARTZ-REEL 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 under "VCC TRIP POINT" for ADM1815-5/ADM1816-5/ADM1817-5/ADM1818-5 variants.
Does the ADM1816-5ARTZ-REEL require an external pull-up resistor?
No, the ADM1816-5ARTZ-REEL includes an internal pull-up resistor of 5.5 kΩ (3.5–7.5 kΩ range) on its open-drain RST pin. This eliminates the need for an external pull-up resistor, simplifying design and reducing BOM count - confirmed in Table 1 under "INTERNAL PULL-UP RESISTOR" and Figure 14 of the datasheet.
What is the reset timeout duration of the ADM1816-5ARTZ-REEL?
The ADM1816-5ARTZ-REEL provides a fixed reset timeout of 150 ms (typical), with a guaranteed range of 100–250 ms. This delay begins when VCC rises above the trip threshold and ensures sufficient power supply stabilization before releasing the reset signal - specified in Table 1 under "RESET ACTIVE TIME" and validated in Figure 6.
Can the ADM1816-5ARTZ-REEL monitor a 5 V supply?
No, the ADM1816-5ARTZ-REEL is configured for 3.06 V threshold and optimized for 3.3 V supply monitoring. For 5 V supervision, Analog Devices specifies the ADM1810–ADM1813 family (e.g., ADM1810-5ARTZ-REEL with 4.62 V threshold). Using ADM1816-5ARTZ-REEL on 5 V would result in continuous reset assertion.
Is the ADM1816-5ARTZ-REEL RoHS compliant and lead-free?
Yes, the "Z" suffix in ADM1816-5ARTZ-REEL explicitly denotes RoHS compliance per Analog Devices' ordering guide (Page 9, footnote 2: "Z = RoHS Compliant Part"). The device uses lead-free matte tin finish and meets JEDEC J-STD-020 moisture sensitivity level 1 standards.
