Product details
Overview
NCX2220GT,115 from NXP Semiconductors is a dual low-voltage, rail-to-rail input/output comparator optimized for ultra-low-power battery-operated systems. It delivers 5 μA per comparator supply current, operates from 1.3 V to 5.5 V, and achieves 0.8 μs typical propagation delay with 20 mV overdrive - enabling precision threshold detection in cellular handsets and portable security sensors.
For engineers reviewing the NCX2220GT,115 datasheet, NCX2220GT,115 pinout, NCX2220GT,115 application, or NCX2220GT,115 equivalent, key selection criteria include guaranteed 1.3 V operation, internal 9 mV hysteresis, −40 °C to +85 °C temperature range, rail-to-rail output swing up to 5 mA drive, and XSON8 (SOT833-1) 1.0 × 1.95 × 0.5 mm package compatibility with space-constrained PCB layouts.
Technical Context
The NCX2220GT,115 integrates two independent comparators with complementary P/N-channel output stages, enabling true rail-to-rail output swing without external pull-ups. Its input stage supports common-mode voltage from VEE to VCC, with no phase inversion beyond rails - critical for accurate zero-crossing and Schmitt-trigger oscillator implementations.
Internal hysteresis (typ. 9 mV) is fixed and unadjustable, providing noise immunity in noisy environments like alarm system sensor interfaces. Propagation delay remains stable across 1.3–5.5 V supply range and −40 °C to +85 °C ambient, verified under 15 pF capacitive load conditions.
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), 3.0 V logic, and legacy 5.0 V systems without level shifting. |
| Supply Current (per comp) | 5.0 μA typical - allows >1-year battery life in always-on wake-up circuits drawing <10 μA total quiescent current. |
| Propagation Delay | 0.8 μs typical at 20 mV overdrive - supports fast response in overvoltage protection and edge-detection timing applications. |
| Hysteresis Voltage | 9 mV typical - suppresses chatter on slow-moving or noisy analog inputs such as thermistor-based temperature monitors. |
| Input Offset Voltage | ±30 mV max over temperature - ensures reliable switching at small differential signals in low-gain sensor front-ends. |
| Output Drive Capability | Rail-to-rail swing with ±5 mA drive - directly interfaces with CMOS logic, LED drivers, or MOSFET gate control without buffering. |
| Operating Temperature | −40 °C to +85 °C - qualified for industrial and consumer-grade portable equipment deployment. |
Pinout & Package
XSON8 package (SOT833-1): plastic extremely thin small outline, no leads, 8 terminals, body dimensions 1.0 × 1.95 × 0.5 mm. Pin 1 indicator located at lower-left corner below marking code "q2". Exposed thermal pad (pin 4, VEE) must remain floating or connect to VEE - not soldered to ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Open-drain compatible rail-to-rail output of comparator 1; sinks or sources up to 5 mA. |
| 2 | IN1− | Inverting input of comparator 1; accepts common-mode voltage from VEE to VCC. |
| 3 | IN1+ | Non-inverting input of comparator 1; matched bias current (<1 pA) minimizes offset drift. |
| 4 | VEE | Negative supply terminal (GND reference); also serves as thermal pad anchor point. |
| 5 | IN2+ | Non-inverting input of comparator 2; electrically isolated from IN1+ with <1 pA leakage. |
| 6 | IN2− | Inverting input of comparator 2; supports same rail-to-rail common-mode range as IN1±. |
| 7 | OUT2 | Independent rail-to-rail output of comparator 2; fully decoupled from OUT1 switching noise. |
| 8 | VCC | Positive supply terminal; supplies both comparators; PSRR ≥45 dB reduces supply ripple coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode extends 0.1 V beyond VEE/VCC; output swings within 20 mV of rails at 5 mA load - eliminates need for external level shifters. |
| No phase inversion | Guaranteed absence of output polarity reversal when inputs exceed supply rails - essential for robust overvoltage/undervoltage lockout circuits. |
| Internal hysteresis | Fixed 9 mV typical hysteresis - provides built-in noise margin without external feedback resistors, simplifying Schmitt trigger designs. |
| Ultra-low power | 5 μA per comparator at 25 °C - enables continuous monitoring in energy-harvesting nodes and coin-cell-powered IoT endpoints. |
| ESD robustness | HBM Class 3A (>2000 V) and CDM (>1000 V) - withstands handling in non-ESD-controlled assembly environments. |
Applications
| Cellular Telephone Power Monitoring | Portable Security System Sensor Interface |

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 (1.8 μA per comp), wider temp range (−40 °C to +125 °C), no internal hysteresis. | Requires external hysteresis resistors; better suited for automotive-qualified designs needing extended temperature support. | Select TLV3702IDR only if 125 °C operation or lower input bias current (0.5 pA) is required - NCX2220GT,115 offers superior hysteresis integration and 1.3 V start-up. |
| MAX9062ASA+ | Higher propagation delay (1.5 μs), higher supply current (12 μA), includes shutdown pin. | Shutdown feature enables dynamic power gating; less suitable for always-on sensing due to higher quiescent draw. | Choose MAX9062ASA+ only when active power cycling is needed; NCX2220GT,115 delivers lower static power and faster response for persistent monitoring. |
Compared with TLV3702IDR and MAX9062ASA+, the NCX2220GT,115 uniquely combines 1.3 V operation, integrated 9 mV hysteresis, and 5 μA supply current - making it optimal for space- and energy-constrained portable electronics where simplicity and ultra-low quiescent power are mandatory.
