Product details
Overview
ADM6315-29D2ARTZR7 from Analog Devices is a precision open-drain microprocessor supervisory circuit designed to monitor 2.93 V supply rails with ±2.5% threshold accuracy over −40°C to +85°C, 20 ms minimum reset timeout, and 5 μA typical supply current. It asserts active-low RESET during power-up, brownout (35 μs response), or manual reset via debounced MR input, and is used in automotive safety systems requiring reliable power sequencing.
For engineers reviewing the ADM6315-29D2ARTZR7 datasheet, ADM6315-29D2ARTZR7 pinout, ADM6315-29D2ARTZR7 application, or ADM6315-29D2ARTZR7 equivalent, key selection criteria include reset threshold tolerance at temperature, manual reset glitch immunity (100 ns rejection), open-drain output sink capability (3.2 mA @ 4.25 V), and SOT-143 package compatibility with space-constrained embedded controllers.
Technical Context
The ADM6315-29D2ARTZR7 integrates a precision bandgap reference, comparator with hysteresis, and monostable timer for deterministic reset assertion. Its voltage monitor detects as little as 1.8% supply degradation, and the internal timing circuit guarantees ≥20 ms RESET low duration after VCC rises above 2.93 V or MR deasserts.
It features an open-drain RESET output compatible with higher-voltage logic domains, a debounced manual reset input accepting ≥1 μs pulses, and operates down to VCC = 1 V while maintaining reset assertion-enabling robust brownout detection in automotive and industrial power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reset Threshold | 2.93 V ±2.5% over −40°C to +85°C - ensures reliable detection of 2.93 V rail collapse without false triggers. |
| Reset Timeout | 20 ms minimum - guarantees sufficient system stabilization time before processor release from reset. |
| Supply Current | 5 μA typical at 5.5 V - enables ultra-low-power operation in battery-backed or energy-sensitive applications. |
| VCC Operating Range | 1 V to 5.5 V - supports reset assertion even during deep brownout conditions below nominal supply. |
| MR Input Glitch Rejection | 100 ns - prevents spurious resets from EMI or switch bounce in noisy automotive environments. |
| RESET Response Time | 35 μs typical for 1 mV/μs VCC fall rate - synchronizes system-wide reset before any subsystem drops below operational voltage. |
Pinout & Package
The ADM6315-29D2ARTZR7 is housed in a 4-lead SOT-143 package (RA-4), measuring 2.9 mm × 1.6 mm × 1.15 mm, with gull-wing leads optimized for automated assembly and thermal performance (θJA = 330°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Ground Reference | 0 V return path for all internal circuits; must be connected directly to system ground plane for noise immunity. |
| RESET (Pin 2) | Open-Drain Active-Low Output | Sinks up to 3.2 mA; requires external pull-up to logic domain voltage (e.g., 3.3 V or 5 V) for interfacing with diverse host processors. |
| MR (Pin 3) | Debounced Manual Reset Input | Active-low; accepts ≥1 μs pulses; floating when unused; decoupling capacitor recommended in noisy environments. |
| VCC (Pin 4) | Monitored Supply Voltage Input | Connects directly to the 2.93 V rail being supervised; powers internal circuitry and defines reset threshold reference. |
Key Features
| Feature | Design Value |
|---|---|
| Precision Voltage Monitoring | 2.93 V threshold with ±2.5% tolerance across −40°C to +85°C - eliminates need for external trimming in production calibration. |
| Ultra-Low Quiescent Current | 5 μA typical - extends battery life in portable instruments and reduces self-heating in sealed enclosures. |
| Brownout Detection Speed | 35 μs response to 1 mV/μs VCC drop - ensures coordinated reset before microcontroller registers corrupt. |
| Manual Reset Debouncing | 100 ns glitch rejection and 1 μs minimum pulse acceptance - removes need for external RC filtering in panel-mounted reset switches. |
| Wide Supply Range Operation | Functional reset assertion down to VCC = 1 V - supports fail-safe behavior during catastrophic power collapse. |
Applications
| Automotive Safety ECUs | Industrial PLC Controllers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microprocessor supervisory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6315US29D2+T | 2.93 V threshold, 20 ms timeout, but 10 μA typical supply current and −40°C to +85°C temp range only. | Lacks extended temperature support (−40°C to +125°C) and has higher quiescent current - less suitable for under-hood automotive use. | Select ADM6315-29D2ARTZR7 for designs requiring full automotive-grade temperature range and ultra-low power. |
| TPS3808G33DBVR | 3.3 V fixed threshold, 20 ms timeout, push-pull RESET output, 16 μA typical current, −40°C to +125°C. | Fixed 3.3 V threshold incompatible with 2.93 V rails; push-pull output lacks voltage-level translation flexibility of open-drain. | Choose ADM6315-29D2ARTZR7 when precise 2.93 V monitoring and open-drain interoperability with mixed-voltage systems are required. |
Compared with MAX6315US29D2+T and TPS3808G33DBVR, the ADM6315-29D2ARTZR7 uniquely combines 2.93 V precision monitoring, 20 ms timeout, −40°C to +125°C operation, 5 μA quiescent current, and open-drain RESET - making it optimal for space- and power-constrained automotive and industrial supervisors where exact threshold matching and logic-domain flexibility are critical.

FAQ
What is the exact reset threshold voltage of the ADM6315-29D2ARTZR7?
The ADM6315-29D2ARTZR7 has a nominal reset threshold of 2.93 V, with tolerance of ±2.5% over −40°C to +85°C and ±3.5% over −40°C to +125°C. This value is laser-trimmed at wafer test and verified per Analog Devices' production specifications - the "29" in the part number explicitly denotes the 2.93 V trip point.
Does the ADM6315-29D2ARTZR7 support manual reset, and how is it implemented?
Yes, the ADM6315-29D2ARTZR7 includes a dedicated MR (Manual Reset) input on Pin 3. It is an active-low, debounced input that rejects glitches shorter than 100 ns and reliably accepts pulses ≥1 μs. When pulled low, it forces RESET low regardless of VCC level - enabling hardware-initiated system recovery without software intervention.
What is the minimum VCC voltage at which the ADM6315-29D2ARTZR7 can assert RESET?
The ADM6315-29D2ARTZR7 continues to assert RESET down to VCC = 1 V, as specified in the Absolute Maximum Ratings and functional operation tables. This ensures fail-safe reset behavior even during severe brownout events where the monitored rail collapses well below its nominal 2.93 V value.
Is the ADM6315-29D2ARTZR7 pin-compatible with other supervisory ICs?
Yes, the ADM6315-29D2ARTZR7 is pin-compatible with the ADM811 series in the same SOT-143 package. Pin assignments (GND, RESET, MR, VCC) match exactly, allowing direct replacement in existing layouts - provided the reset threshold and timeout requirements align with the target application.
What is the guaranteed reset timeout period for the ADM6315-29D2ARTZR7?
The ADM6315-29D2ARTZR7 provides a guaranteed minimum reset timeout of 20 ms after VCC rises above the 2.93 V threshold and MR is released. This value is tested and specified across −40°C to +85°C (20 ms min) and −40°C to +125°C (16 ms min), ensuring deterministic release timing in thermal-critical applications.
