Product details
Overview
ADCMP361YRJZ-REEL7 from Analog Devices is a single high-accuracy comparator with integrated 400 mV ±0.275% reference, dual open-drain outputs, 6.5 µA typical quiescent current, and operation from 1.7 V to 5.5 V supply. It features 9.3 mV typical internal hysteresis and input range extending to ground-designed for low-voltage supply monitoring in Li-ion battery systems.
For engineers reviewing the ADCMP361YRJZ-REEL7 datasheet, ADCMP361YRJZ-REEL7 pinout, ADCMP361YRJZ-REEL7 application, or ADCMP361YRJZ-REEL7 equivalent, key selection considerations include threshold accuracy over temperature, dual-polarity output flexibility, automotive-grade qualification (−40°C to +125°C), and SOT-23 footprint compatibility in space-constrained portable and industrial monitoring designs.
Technical Context
The ADCMP361YRJZ-REEL7 integrates a precision 400 mV reference directly tied to the inverting input of a rail-to-rail input comparator; the noninverting input is externally accessible. Its dual open-drain outputs (OUT and OUT) provide complementary logic states, enabling both inverting and noninverting configurations without external inversion logic.
Internal hysteresis of 9.3 mV (typical) is fixed and unadjustable, reducing susceptibility to noise near the switching threshold. The device guarantees >5 mA sink capability per output across temperature, with output voltage tolerance up to 5.5 V independent of VDD-supporting mixed-voltage interface applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Threshold Voltage | 400 mV ±0.275% at 25°C - enables accurate low-voltage detection (e.g., Li-ion cell under-voltage lockout at ~2.27 V) |
| Supply Range | 1.7 V to 5.5 V - supports direct operation from single-cell Li-ion (2.7–4.2 V) or 3.3 V/5 V rails without level shifting |
| Quiescent Current | 6.5 µA typical - allows continuous battery monitoring in multi-year portable devices with minimal drain |
| Hysteresis | 9.3 mV typical - suppresses chatter on slow-moving or noisy signals without requiring external feedback components |
| Input Range | Includes GND - permits direct monitoring of signals referenced to system ground (e.g., battery cathode sensing) |
| Output Type | Dual open-drain outputs - enables wired-OR logic, level translation up to 5.5 V, and flexible pull-up configuration |
| Propagation Delay | 8–10 µs (LH/HL) at 5 V - suitable for sub-100 kHz threshold event detection with deterministic timing |
Pinout & Package
ADCMP361YRJZ-REEL7 is housed in a RoHS-compliant 5-lead SOT-23 package (JEDEC MO-178-AA, package option RJ-5), measuring 2.90 mm × 1.60 mm × 1.15 mm with gull-wing leads. This compact outline supports high-density PCB layouts in handheld and automotive ECUs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Noninverting Open-Drain Output | Active-low when IN > 400 mV; requires external pull-up for logic HIGH; complements Pin 5 |
| 2 (GND) | Ground Reference | Primary return path for internal reference and comparator; must be low-impedance for accuracy |
| 3 (IN) | Analog Input | Monitors external voltage; comparator compares this against internal 400 mV reference |
| 4 (VDD) | Power Supply | Accepts 1.7–5.5 V; decoupling capacitor (100 nF) recommended between Pin 4 and Pin 2 |
| 5 (OUT) | Inverting Open-Drain Output | Active-low when IN < 400 mV; logic inverse of Pin 1; supports differential signaling or redundancy |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 400 mV Reference | ±0.275% accuracy eliminates need for external precision reference, reducing BOM count and layout area |
| Dual Complementary Outputs | Enables direct connection to optoisolators or relays without inverters-simplifies threshold-driven actuation circuits |
| Ground-Sensing Input | Supports direct cathode-side battery monitoring in Li-ion packs without high-side sensing circuitry |
| Automotive-Qualified | Rated −40°C to +125°C with controlled manufacturing-meets AEC-Q100 stress test requirements for ECU use |

Applications
| Li-Ion Battery Monitoring | Industrial Threshold Detection |
|---|---|
|
Use Scenario: Real-time monitoring of single-cell Li-ion voltage during charge/discharge cycles to trigger cutoff at 2.27 V. IC Role / Device Role / Timing Role: Comparator with built-in reference detects crossing of 400 mV threshold on scaled battery voltage (e.g., via 1 MΩ/4.7 MΩ divider). Use Value: Eliminates external reference and reduces component count by 3–4 parts while maintaining ±0.275% trip-point accuracy over temperature. |
Use Scenario: Detecting overtemperature conditions in motor drives using an NTC thermistor network. IC Role / Device Role / Timing Role: High-accuracy threshold detector comparing thermistor voltage against 400 mV reference to assert fault signal. Use Value: Internal hysteresis prevents relay chatter near trip point; dual outputs allow simultaneous activation of alarm LED and shutdown latch. |
| Optoisolator Driving | Relay Control Interface |
|
Use Scenario: Isolating microcontroller GPIO from high-voltage AC mains sensing circuitry. IC Role / Device Role / Timing Role: Level-shifting comparator driving optocoupler LED with open-drain output pulled to 5 V or 12 V. Use Value: Output tolerates up to 5.5 V-enables direct drive of 4N25/PC817 LEDs without series transistor or level shifter. |
Use Scenario: Controlling 12 V automotive relay coils from 3.3 V MCU I/O pins. IC Role / Device Role / Timing Role: High-current sink output (≥5 mA) directly energizes relay coil via open-drain stage with external 12 V pull-up. Use Value: Dual outputs allow one to drive relay and second to feed back status to MCU-no additional logic required. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator-with-reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3011IDBVR | 2.5 V internal reference; no hysteresis; 1.8–5.5 V supply; 12 µA IQ | Lacks integrated hysteresis and 400 mV threshold-requires external hysteresis network and scaling resistors | Choose only if higher reference voltage suffices and board space allows added components |
| MAX9063ASA+ | 400 mV reference; no hysteresis; 1.6–5.5 V supply; 12 µA IQ; single open-drain output | Single output limits configurability; no internal hysteresis necessitates external feedback | Select when dual outputs and built-in hysteresis are not required-reduces cost but increases design complexity |
Compared with TLV3011IDBVR and MAX9063ASA+, ADCMP361YRJZ-REEL7 uniquely combines 400 mV ±0.275% reference, fixed 9.3 mV hysteresis, and dual complementary open-drain outputs in a single SOT-23 package-reducing external component count and improving reliability in battery and automotive monitoring.

FAQ
What is the exact threshold voltage tolerance of ADCMP361YRJZ-REEL7 over temperature?
The ADCMP361YRJZ-REEL7 has a threshold voltage accuracy of ±0.275% at 25°C, with a temperature coefficient of 16 ppm/°C. Over the full −40°C to +125°C range, rising input threshold varies from 391.2 mV to 407.7 mV depending on supply voltage-verified in Table 1 of the datasheet under "Rising Input Threshold Voltage" test conditions.
Does ADCMP361YRJZ-REEL7 require external hysteresis components?
No. ADCMP361YRJZ-REEL7 includes 9.3 mV typical internal hysteresis, eliminating the need for external positive feedback resistors. This fixed hysteresis is effective for noise suppression in most low-speed monitoring applications such as battery voltage detection and thermal cutoffs.
Can ADCMP361YRJZ-REEL7 drive a 12 V relay directly?
Yes. The open-drain outputs of ADCMP361YRJZ-REEL7 tolerate up to 5.5 V, but they can sink ≥5 mA at VOL ≤ 220 mV-sufficient to drive relay coils when used with an external 12 V pull-up resistor. The output stage is not rated for 12 V rail switching; external pull-up is mandatory.
Is ADCMP361YRJZ-REEL7 qualified for automotive applications?
Yes. ADCMP361YRJZ-REEL7 is rated for −40°C to +125°C and manufactured under controlled processes meeting automotive quality requirements. While the "W" variant (ADCMP361WRJZ-RL7) is explicitly branded for automotive use, the "Y" grade shares identical electrical specs and temperature rating-confirmed in the Ordering Guide and Automotive Products section.
How does the dual-output architecture of ADCMP361YRJZ-REEL7 improve system design?
The dual open-drain outputs (OUT and OUT) of ADCMP361YRJZ-REEL7 provide complementary logic states-enabling simultaneous control of active-high and active-low loads (e.g., relay + status LED) without external inverters. This reduces component count, PCB area, and potential timing skew in safety-critical monitoring paths.
