Product details
Overview
NCX2220GU,115 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 at 20 mV overdrive - enabling precise voltage monitoring in cellular telephones and portable security sensors.
For engineers reviewing the NCX2220GU,115 datasheet, NCX2220GU,115 pinout, NCX2220GU,115 application, or NCX2220GU,115 equivalent, this device supports design of compact, long-life analog front-ends requiring sub-2 V operation, internal hysteresis for noise immunity, and rail-to-rail output drive capability up to 5 mA without external pull-ups.
Technical Context
The NCX2220GU,115 integrates two independent comparators with complementary P/N-channel output stages, enabling true rail-to-rail output swing across its full 1.3–5.5 V supply range. Its input common-mode range extends 0.1 V beyond both rails, eliminating phase inversion during overdrive - critical for zero-crossing detection and Schmitt-trigger oscillator circuits.
Internal hysteresis (typ. 9 mV) is fixed and non-adjustable, providing consistent noise margin without external components. The device uses die-level ESD protection meeting HBM Class 3A (>2000 V) and CDM (>1000 V), supporting robust operation in handheld and industrial edge nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.3 V to 5.5 V - enables direct use in single-cell Li-ion (3.0 V), coin-cell (1.5 V), and legacy 5.0 V systems without level-shifting. |
| Supply Current (per comparator) | 5.0 μA typical - allows continuous monitoring in multi-year battery applications (e.g., smoke detectors, wearable health sensors). |
| Propagation Delay | 0.8 μs typical at 20 mV overdrive - supports fast response in overvoltage/undervoltage lockout and pulse-width modulation feedback loops. |
| Input Offset Voltage | ±30 mV max (−40 °C to +85 °C) - sufficient for threshold detection in alarm systems where precision <10 mV is not required. |
| Hysteresis Voltage | 6–13 mV (typ. 9 mV) - provides built-in noise immunity for reliable switching in electrically noisy environments like motor control interfaces. |
| Output Drive Capability | Rail-to-rail swing with ±5 mA sink/source - eliminates need for external pull-up resistors in logic-level translation or LED driver interface circuits. |
| Operating Temperature | −40 °C to +85 °C - qualified for consumer and industrial ambient conditions without derating. |
Pinout & Package
NCX2220GU,115 is housed in an 8-terminal HXSON package (SOT972-2), measuring 1.35 × 1.7 × 0.5 mm, with thermal-enhanced construction and no leads. Pin 1 is located at the lower-left corner below the marking code "q2". The exposed substrate pad (terminal 4) is electrically connected to VEE but requires no solder connection unless used for thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Open-drain compatible rail-to-rail output for comparator 1; sinks up to 5 mA or sources up to 5 mA. |
| 2 | IN1− | Inverting input for comparator 1; accepts common-mode voltages from VEE − 0.1 V to VCC + 0.1 V. |
| 3 | IN1+ | Non-inverting input for comparator 1; identical common-mode range as IN1−. |
| 4 | VEE | Negative supply terminal (typically ground); also connects to thermally enhanced substrate pad. |
| 5 | IN2+ | Non-inverting input for comparator 2; fully independent from comparator 1 inputs. |
| 6 | IN2− | Inverting input for comparator 2; supports same overdrive tolerance and rail extension as IN1±. |
| 7 | OUT2 | Independent rail-to-rail output for comparator 2; electrically isolated from OUT1. |
| 8 | VCC | Positive supply terminal; supplies both comparators; must be decoupled locally with ≥100 nF ceramic capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode extends 0.1 V beyond VEE and VCC; output swings within 20 mV of either rail at 5 mA load - simplifies interfacing with mixed-voltage MCUs. |
| Ultra-low quiescent current | 5 μA per comparator at 25 °C - reduces standby power by >90% vs. standard comparators, extending battery life in always-on sensing nodes. |
| Fixed internal hysteresis | 9 mV typical - eliminates need for external positive feedback resistors in threshold-detection circuits, saving PCB area and BOM cost. |
| No phase inversion on overdrive | Guaranteed stable output polarity even when inputs exceed supply rails - essential for accurate zero-crossing detection in AC line monitoring. |
| ESD robustness | HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events without latch-up or parameter shift in portable electronics assembly. |
Applications
| Cellular Telephone Power Monitoring | Portable Security System Threshold Detection |

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 offset range (±3.5 mV), no internal hysteresis - requires external feedback resistors. | Better precision for instrumentation; unsuitable for noise-prone environments without added components. | Choose TLV3702IDR only if offset voltage <5 mV is mandatory and board space allows hysteresis resistors. |
| MAX9062ASA+ | Wider supply range (1.6–5.5 V), higher speed (120 ns propagation), but 12 μA supply current - 2.4× higher than NCX2220GU,115. | Preferred for high-speed window comparators; less suitable for multi-year battery operation. | Select MAX9062ASA+ when response time <200 ns is required and power budget permits >10 μA per comparator. |
Compared with TLV3702IDR and MAX9062ASA+, the NCX2220GU,115 uniquely balances ultra-low power (5 μA), built-in hysteresis, and rail-to-rail operation in a 1.7 mm × 1.35 mm package - making it optimal for space-constrained, long-life portable electronics where precision is secondary to efficiency and simplicity.

FAQ
What is the minimum operating voltage for NCX2220GU,115?
The NCX2220GU,115 is guaranteed to operate down to 1.3 V, with full functionality including rail-to-rail input and output performance, internal hysteresis, and 0.8 μs propagation delay. At 1.3 V, supply current remains at 5 μA per comparator, making NCX2220GU,115 suitable for single alkaline or lithium coin-cell applications where headroom is minimal.
Does NCX2220GU,115 require external hysteresis components?
No, NCX2220GU,115 includes fixed internal hysteresis of 6–13 mV (typ. 9 mV), eliminating the need for external positive feedback resistors. This simplifies circuit design for threshold detection in alarm systems and battery monitors, reduces component count, and improves consistency across temperature and process variation - all while retaining the same pinout and layout as standard comparators.
Can NCX2220GU,115 drive a 5 mA load at 1.3 V supply?
Yes, NCX2220GU,115 delivers rail-to-rail output swing with ±5 mA sink/source capability across its entire 1.3–5.5 V supply range. At 1.3 V, the HIGH-level output voltage is 1.24 V (IO = −0.5 mA), and LOW-level is 0.05 V (IO = 0.5 mA), confirming usable drive strength even at minimum supply - critical for interfacing with low-voltage logic or LED indicators in NCX2220GU,115-based designs.
What package type is used for NCX2220GU,115?
NCX2220GU,115 uses the HXSON8 package (SOT972-2): a leadless, thermally enhanced 8-terminal outline measuring 1.35 mm × 1.7 mm × 0.5 mm. Pin 1 is marked in the lower-left corner beneath the "q2" top-side marking. The exposed substrate pad (terminal 4) connects to VEE and may be left floating or tied to ground for improved thermal performance - no soldering is required for electrical functionality.
Is NCX2220GU,115 suitable for zero-crossing detection in AC line monitoring?
Yes, NCX2220GU,115 is explicitly validated for zero-crossing detection (see Figure 17 in datasheet). Its rail-to-rail input stage accepts common-mode voltages 0.1 V beyond VEE and VCC, and it exhibits no phase inversion when inputs are overdriven - ensuring clean, chatter-free transitions at AC waveform crossings. This behavior is guaranteed across −40 °C to +85 °C, making NCX2220GU,115 reliable in mains-powered consumer electronics.
