Product details
Overview
NCX2202GW,125 from NXP Semiconductors is a single low-voltage, low-power comparator with open-drain output, designed for rail-to-rail input/output operation across 1.3 V to 5.5 V supply. It delivers 6 µA typical supply current, 0.8 µs typical propagation delay at 20 mV overdrive, and internal 9 mV hysteresis-enabling reliable threshold detection in battery-powered sensor interfaces and portable power management circuits.
For engineers reviewing the NCX2202GW,125 datasheet, NCX2202GW,125 pinout, NCX2202GW,125 application, or NCX2202GW,125 equivalent, key selection criteria include ultra-low quiescent current, guaranteed 1.3 V operation, open-drain flexibility for level translation, and ESD robustness (HBM >1500 V) in space-constrained TSSOP5 packaging.
Technical Context
The NCX2202GW,125 implements a CMOS input stage with picoampere-level input bias current (1.0 pA typ) and rail-to-rail common-mode input range extending 0.1 V beyond both supply rails. Its internal hysteresis (6–13 mV) eliminates noise-induced oscillation without external components.
Dynamic behavior is characterized by fast switching: 0.8 µs propagation delay (20 mV overdrive, CL = 15 pF), sub-10 ns transition time (VCC = 5.5 V, CL = 50 pF), and stable performance across −40 °C to +85 °C ambient temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage range | 1.3 V to 5.5 V functional operation-supports direct integration into 1.8 V, 3.0 V, and 5.0 V systems without level-shifting. |
| Supply current | 6.0 µA typical-enables multi-year battery life in always-on monitoring applications. |
| Propagation delay | 0.8 µs typical at 20 mV input overdrive-suitable for medium-speed event detection (e.g., zero-crossing, window comparators). |
| Hysteresis voltage | 6–13 mV (typ 9 mV)-provides inherent noise immunity for clean digital output transitions in noisy environments. |
| Input offset voltage | ±30 mV max (−40 °C to +85 °C)-ensures predictable trip-point accuracy across industrial temperature range. |
| ESD protection | HBM >1500 V, CDM >1000 V-meets IEC 61000-4-2 Level 2 requirements for handheld and portable equipment. |
| Output configuration | Open-drain N-channel-allows wired-OR logic, flexible pull-up voltage selection (up to 5.5 V), and bidirectional level translation. |
Pinout & Package
TSSOP5 (SOT353-1) package: plastic thin shrink small outline, 5-lead, 1.25 mm body width, lead pitch 0.65 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Open-drain comparator output-requires external pull-up; sinks up to 5 mA to VEE. |
| 2 | VEE | Negative supply terminal-typically connected to ground (0 V) in single-supply configurations. |
| 3 | IN+ | Non-inverting input-accepts rail-to-rail common-mode voltage (VEE to VCC). |
| 4 | IN− | Inverting input-identical common-mode range; no phase inversion when overdriven. |
| 5 | VCC | Positive supply terminal-supports 1.3 V to 5.5 V; powers internal circuitry and defines output high level via pull-up. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input/output | Enables full utilization of supply rails-critical for low-voltage battery systems where headroom is constrained. |
| No phase inversion on overdrive | Guarantees monotonic output response even when inputs exceed supply rails-eliminates false triggering in transient conditions. |
| Internal hysteresis | Reduces need for external positive feedback components-simplifies PCB layout and lowers BOM count in threshold-detection designs. |
| Ultra-low power consumption | 6 µA supply current enables continuous operation in energy-harvesting and coin-cell-powered devices. |
| Wide temperature range | Specified from −40 °C to +85 °C-validates performance in automotive cabin, industrial control, and outdoor IoT deployments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-voltage comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV3691IDCKR | Higher supply current (150 nA typ), lower hysteresis (1.5 mV), same TSSOP5 package. | Lacks internal hysteresis-requires external feedback for noise immunity; better for precision zero-crossing. | Select when ultra-low offset (<1 mV) and minimal propagation delay (250 ns) outweigh hysteresis needs. |
| MAX9021AXK+T | Wider supply range (1.6 V to 5.5 V), higher ICC (1.5 µA), no internal hysteresis, SOT23-5 package. | Requires external hysteresis resistor network; slightly larger footprint than TSSOP5. | Choose when legacy SOT23-5 compatibility or higher drive strength (8 mA sink) is required. |
Compared with TLV3691IDCKR and MAX9021AXK+T, the NCX2202GW,125 uniquely combines sub-µA quiescent current, built-in hysteresis, and guaranteed 1.3 V operation-making it optimal for long-life, noise-prone, ultra-low-voltage sensing nodes where design simplicity and power efficiency are prioritized.

FAQ
What is the minimum operating voltage for the NCX2202GW,125?
The NCX2202GW,125 is guaranteed to operate down to 1.3 V supply voltage across the full −40 °C to +85 °C temperature range. This specification is verified per NXP's Product Data Sheet Rev. 5.1 and enables direct use with single-cell lithium or alkaline batteries without regulation. The NCX2202GW,125 maintains rail-to-rail input functionality and 6 µA supply current even at this minimum voltage.
Does the NCX2202GW,125 require external hysteresis components?
No, the NCX2202GW,125 integrates 6–13 mV of internal hysteresis, eliminating the need for external positive feedback resistors in most noise-immune threshold detection applications. This feature is confirmed in Table 6 (Static Characteristics) and Section 12.1 of the datasheet. The NCX2202GW,125's internal hysteresis improves reliability in environments with EMI or slow-moving input signals.
Can the NCX2202GW,125 be used as a logic level translator?
Yes, the NCX2202GW,125's open-drain output and rail-to-rail input make it suitable for unidirectional logic level translation-for example, converting 1.8 V logic to 3.3 V or 5 V logic using an external pull-up resistor. Figure 13 in the datasheet explicitly demonstrates this application. The NCX2202GW,125 supports this function across its full 1.3 V to 5.5 V supply range without additional biasing.
What is the maximum output sink current for the NCX2202GW,125?
The NCX2202GW,125 output stage can sink up to 5 mA while maintaining VOL ≤ 0.3 V (tested at VCC = 3.0 V, IO = 3 mA). Absolute maximum ratings permit indefinite short-circuit to VEE, but continuous operation above 5 mA is not characterized. This capability is documented in Table 6 (VOL parameter) and Section 12.2 (Output Stage) of the NCX2202GW,125 datasheet.
Is the NCX2202GW,125 pin-compatible with other NXP comparators in TSSOP5?
The NCX2202GW,125 uses the standard SOT353-1 (TSSOP5) pinout defined in Table 3: Pin 1 = OUT, Pin 2 = VEE, Pin 3 = IN+, Pin 4 = IN−, Pin 5 = VCC. While other NXP comparators like the NCX2200 series share this pinout, direct substitution requires verification of electrical parameters (e.g., hysteresis, propagation delay, supply current) since the NCX2202GW,125 has unique low-voltage optimization.
