Product details
Overview
NCX2220DP,125 from NXP Semiconductors is a dual low-voltage, rail-to-rail input/output comparator optimized for ultra-low-power operation in battery-powered systems. It delivers 5 μA typical supply current per comparator, operates from 1.3 V to 5.5 V, and achieves 0.8 μs typical propagation delay with 20 mV overdrive - enabling precise voltage monitoring in cellular telephones and portable security sensors.
For engineers reviewing the NCX2220DP,125 datasheet, NCX2220DP,125 pinout, NCX2220DP,125 application, or NCX2220DP,125 equivalent, this device supports design of low-quiescent-current threshold detection, Schmitt-trigger oscillators, zero-crossing detectors, and logic-level translation circuits where supply headroom below 1.5 V is required.
Technical Context
The NCX2220DP,125 integrates two independent comparators with internal hysteresis (9 mV typical), rail-to-rail input common-mode range extending 0.1 V beyond rails, and complementary P/N output stage capable of sourcing/sinking up to 5 mA. Its architecture avoids phase inversion under overdriven inputs and eliminates need for external bypass capacitors.
It is specified across −40 °C to +85 °C ambient temperature, with static parameters including ±30 mV input offset voltage, 70 dB CMRR, and 45–80 dB PSRR. Dynamic behavior is characterized at 15 pF load and 20 mV overdrive, ensuring predictable timing in low-noise sensing paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.3 V to 5.5 V - enables direct integration into single-cell Li-ion (2.7–4.2 V), coin-cell (1.5 V), and legacy 3.3/5.0 V systems without level-shifting. |
| Supply Current (per comparator) | 5.0 μA typical - reduces battery drain in always-on wake-up circuits; <7.0 μA max over full temp range ensures consistent lifetime estimation. |
| Propagation Delay | 0.8 μs typical at 20 mV overdrive, 15 pF load - supports >1 MHz threshold-detection loop rates in portable sensor nodes. |
| Input Offset Voltage | ±30 mV max (−40 °C to +85 °C) - defines minimum detectable differential voltage in precision window comparators. |
| Hysteresis Voltage | 6–13 mV (typical 9 mV) - provides built-in noise immunity for reliable switching in EMI-prone environments like handheld RF devices. |
| Output Drive Capability | Rail-to-rail swing with ±5 mA drive - directly interfaces with MCU GPIOs, LED drivers, or MOSFET gates without external buffers. |
| ESD Robustness | HBM Class 3A (>2000 V), CDM >1000 V - withstands handling and board-level ESD events in high-volume consumer assembly lines. |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8-lead, 3 mm body width, 0.4 mm lead pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Open-drain or push-pull output of comparator 1; rail-to-rail swing supports direct connection to 1.8 V/3.3 V logic inputs. |
| 2 | IN1− | Inverting input of comparator 1; common-mode range extends to VEE −0.1 V and VCC +0.1 V, enabling true rail-sensing. |
| 3 | IN1+ | Non-inverting input of comparator 1; matched with IN1− for low offset and high CMRR in differential sensing. |
| 4 | VEE | Negative supply terminal (typically GND); substrate-connected pad requires floating or VEE tie - no solder requirement. |
| 5 | IN2+ | Non-inverting input of comparator 2; independent channel allows dual-threshold or window-comparator configurations. |
| 6 | IN2− | Inverting input of comparator 2; supports independent reference or feedback path for hysteresis control. |
| 7 | OUT2 | Output of comparator 2; identical electrical characteristics to OUT1 for synchronized dual-channel decision logic. |
| 8 | VCC | Positive supply terminal; accepts 1.3–5.5 V with no external regulation needed - simplifies power tree in multi-rail designs. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode range spans VEE −0.1 V to VCC +0.1 V; output swings within 20 mV of rails at 5 mA - eliminates level-shifters in low-VDD systems. |
| Ultra-low quiescent current | 5 μA per comparator typical - enables years of operation on CR2032 coin cells in wireless alarm sensors. |
| No phase inversion | Guaranteed stable output polarity even when inputs exceed supply rails - prevents false triggers in overvoltage fault detection. |
| Internal hysteresis | 9 mV typical hysteresis voltage - suppresses chatter from noisy analog signals without external resistor networks. |
| Wide temperature range | Specified from −40 °C to +85 °C - supports deployment in outdoor security systems and automotive cabin electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3702IDR | Higher supply current (1.3 μA per comparator), wider VCC range (1.8–16 V), no internal hysteresis. | Better suited for higher-voltage industrial sensors; lacks integrated hysteresis requiring external resistors for noise immunity. | Select TLV3702IDR when operating above 5.5 V or needing higher drive strength; avoid if <5 μA quiescent current is mandatory. |
| MAX9062ASA+ | Lower propagation delay (120 ns), higher supply current (12 μA), −40 °C to +125 °C rating. | Preferred for automotive under-hood applications; over-spec'd for consumer portables due to unnecessary temperature margin and power use. | Choose MAX9062ASA+ only when extended temperature range or sub-200 ns response is required; otherwise NCX2220DP,125 offers optimal power/performance balance. |
Compared with TLV3702IDR and MAX9062ASA+, the NCX2220DP,125 uniquely combines sub-5 μA quiescent current, guaranteed 1.3 V operation, and factory-trimmed internal hysteresis - making it the most energy-efficient choice for space-constrained, battery-critical designs where noise immunity and rail-to-rail flexibility are essential.

FAQ
What is the minimum operating voltage for the NCX2220DP,125?
The NCX2220DP,125 is guaranteed to operate down to 1.3 V supply voltage across the full −40 °C to +85 °C temperature range. At 1.3 V, it maintains functional performance including rail-to-rail input operation and internal hysteresis, making it suitable for single-cell alkaline or lithium primary battery applications where voltage drops below 1.5 V.
Does the NCX2220DP,125 require external hysteresis components?
No, the NCX2220DP,125 includes factory-trimmed internal hysteresis of 6–13 mV (typical 9 mV), eliminating the need for external positive-feedback resistors. This simplifies PCB layout, reduces component count, and ensures consistent noise immunity across temperature and process variations - a key advantage over comparators like TLV3702IDR that lack integrated hysteresis.
Can the NCX2220DP,125 drive an LED directly?
Yes, the NCX2220DP,125 outputs can source or sink up to 5 mA while maintaining rail-to-rail swing. At VCC = 3.0 V, the HIGH-level output voltage remains ≥2.85 V at −3 mA, and LOW-level voltage stays ≤0.14 V at +3 mA - sufficient to directly drive low-current indicator LEDs without additional transistor buffering in most portable designs.
What is the pin 1 identifier on the NCX2220DP,125 TSSOP8 package?
On the NCX2220DP,125 in TSSOP8 (SOT505-2) packaging, pin 1 is located at the lower-left corner of the device body, below the marking code "q2". The physical indicator is a small bevelled edge or dot adjacent to pin 1, consistent with JEDEC-standard TSSOP orientation for automated optical recognition during placement.
Is the NCX2220DP,125 qualified for automotive applications?
No, the NCX2220DP,125 is not automotive-qualified. It is rated for −40 °C to +85 °C operation and intended for industrial and consumer applications such as cellular telephones and security systems. For automotive use, NXP offers AEC-Q100 qualified alternatives like the LMV339QDRQ1, which undergo additional stress testing and failure analysis per automotive standards.
