Product details
Overview
APX393SG-13 from Diodes Incorporated is a dual low-voltage rail-to-rail input comparator with open-drain outputs, operating from 2.5V to 5.5V supply, featuring 60 µA per channel supply current, ±200 mV input offset voltage max at 5V, and propagation delay as low as 200 ns (100 mV overdrive). It is used in battery-powered portable electronics for level detection and signal conditioning.
For engineers reviewing the APX393SG-13 datasheet, APX393SG-13 pinout, APX393SG-13 application, or APX393SG-13 equivalent, key selection criteria include rail-to-rail input range (V− +0.2 V to V+ −0.2 V), low quiescent current, open-drain output compatibility with mixed-voltage logic interfaces, and industrial temperature operation (−40°C to +85°C).
Technical Context
The APX393SG-13 implements two independent comparators in a single SOP-8L package, each with CMOS input stage enabling rail-to-rail common-mode input voltage range and low input bias current (max 400 nA at 5V). Its open-drain outputs require external pull-up resistors and support interfacing across 1.8V, 3.3V, and 5V logic families.
Designed for low-power portable systems, it delivers guaranteed performance at both 2.7V and 5V supplies, with saturation voltage ≤200 mV at 1 mA sink current and thermal resistance θJA = 150 °C/W in SOP-8L. Propagation delays are specified down to 200 ns (TPHL) and 300 ns (TPLH) under 100 mV input overdrive at 5V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports single-cell Li-ion (3.0–3.7 V) and dual-cell alkaline (3.0 V) as well as standard 3.3 V/5 V rails |
| Input Common-Mode Range | V− +0.2 V to V+ −0.2 V - enables full-rail sensing without external level-shifting circuitry |
| Supply Current per Channel | 150–250 µA - ensures <500 µA total for dual-channel operation, critical for multi-year battery life |
| Output Type | Open-drain - allows wired-OR logic, flexible pull-up voltage selection, and interface with higher-voltage logic |
| Propagation Delay (5V, 100 mV overdrive) | 200 ns (TPHL), 300 ns (TPLH) - sufficient for medium-speed monitoring (e.g., battery charge state, power-good assertion) |
| Input Offset Voltage (max) | 9 mV at 5V - sets minimum detectable differential for precision thresholding in sensor interfaces |
| Saturation Voltage (ISINK ≤1 mA) | ≤200 mV - reduces logic-low voltage margin loss when driving standard CMOS/TTL inputs |
Pinout & Package
SOP-8L package: 8-pin small-outline plastic package, 5.9 mm × 4.9 mm body, 1.27 mm pitch, RoHS-compliant lead-free finish, green molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Open-drain output of Comparator A - requires external pull-up; sinks current when IN+ > IN− |
| 2 | INA− | Inverting input of Comparator A - accepts rail-to-rail analog signals from 0.2 V below V+ to 0.2 V above V− |
| 3 | INA+ | Non-inverting input of Comparator A - same input voltage range as INA−; differential pair with sub-µA bias current |
| 4 | V− | Negative supply pin - connects to ground or negative rail; reference for all internal circuitry |
| 5 | V+ | Positive supply pin - powers both comparators; supports 2.5–5.5 V with stable operation across temperature |
| 6 | INB− | Inverting input of Comparator B - electrically identical to INA−; enables dual-threshold or window detection |
| 7 | INB+ | Non-inverting input of Comparator B - independent of Comparator A; supports separate signal paths |
| 8 | OUTB | Open-drain output of Comparator B - independently controllable; shares no internal nodes with OUTA |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Enables direct sensing of signals near supply rails without attenuation or clamping diodes |
| Low 60 µA/channel supply current | Reduces system-level standby power by >80% vs. legacy bipolar comparators (e.g., LM393) |
| Guaranteed 2.7 V and 5 V operation | Eliminates need for separate 3.3 V LDO when interfacing with mixed-supply microcontrollers |
| ESD robustness (HBM 4000 V) | Supports handling and assembly in standard manufacturing environments without special ESD controls |
| Green molding compound (no Br/Sb) | Meets halogen-free requirements for consumer electronics sold in EU, Japan, and China markets |
Applications
| Battery Voltage Monitor | Power-Good Detection |
|---|---|
Use Scenario: Monitoring lithium-ion cell voltage during charging/discharging to trigger cutoff or alert. IC Role / Device Role / Timing Role: Dual comparator configured as high/low threshold detector with hysteresis via feedback resistors. Use Value: 60 µA total quiescent current extends battery runtime; rail-to-rail inputs directly sense 2.8 V–4.2 V cell range without scaling. | Use Scenario: Validating stable 3.3 V or 5 V supply before enabling downstream logic or RF modules. IC Role / Device Role / Timing Role: Single comparator comparing regulated rail against precision reference (e.g., TLV431). Use Value: Open-drain output pulls host MCU's reset line low on fault; 200 ns response ensures fast fault containment. |
| USB Port Power Switch Control | Portable Sensor Interface Thresholding |
Use Scenario: Enabling/disabling USB VBUS switch based on host enumeration status or overcurrent flag. IC Role / Device Role / Timing Role: Comparator compares current-sense voltage against programmable trip point to control MOSFET gate driver. Use Value: Low input bias current avoids error in high-impedance current-sense networks; 200 mV saturation voltage ensures clean logic-low signaling. | Use Scenario: Converting analog output from ambient light or temperature sensor into digital presence/absence signal. IC Role / Device Role / Timing Role: Comparator compares sensor output to fixed or adjustable reference to generate wake-up interrupt. Use Value: 9 mV max input offset ensures consistent triggering across units; rail-to-rail input accommodates sensor's full dynamic range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual open-drain comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Higher supply current (500 µA typical), wider offset (±7 mV), no rail-to-rail input (VCM = 0 to V+ −1.5 V) | Not suitable for low-voltage (<3 V) or rail-sensing applications; requires level-shifting for 1.8 V logic | Select when cost is primary concern and supply >3.3 V with ample headroom |
| TLV3702IDR | Lower supply current (800 nA), rail-to-rail input/output, but push-pull output (no open drain) | Cannot perform wired-OR or interface with mixed-voltage buses without external logic | Select only if push-pull drive is acceptable and ultra-low power dominates design priority |
Compared with LM393DR and TLV3702IDR, APX393SG-13 uniquely balances ultra-low quiescent current (150 µA/channel), true rail-to-rail input, and open-drain flexibility-making it optimal for space-constrained, battery-operated systems requiring multi-voltage logic interoperability.

FAQ
Can APX393SG-13 operate from a single 2.5 V supply?
Yes. The APX393SG-13 is fully specified from 2.5 V to 5.5 V supply voltage. At 2.5 V, it maintains rail-to-rail input operation (0.2 V to 2.3 V common-mode range), 60 µA per channel supply current, and functional open-drain outputs with ≤200 mV saturation voltage at 1 mA sink current, as confirmed in the Rev. 5 datasheet Section 3 (Electrical Characteristics).
Does APX393SG-13 require external hysteresis for stable switching?
No internal hysteresis is provided. Stable switching in noisy environments requires external positive feedback (e.g., resistor from OUTA to INA+) to introduce 10–50 mV of hysteresis. This is standard practice for open-drain comparators and is explicitly supported by the device's input voltage range and output drive capability per datasheet Figure 10 and application note AP02001.
What is the maximum sink current capability of APX393SG-13 outputs?
The outputs are rated for 5 mA minimum sink current at VO ≤ 1.5 V (2.7 V supply) and 10 mA minimum at VO ≤ 1.5 V (5 V supply), with typical performance up to 20 mA (2.7 V) and 60 mA (5 V). Absolute maximum rating is 20 mA continuous per output, as defined in the Absolute Maximum Ratings table (Section 2) of the datasheet.
Is APX393SG-13 pin-compatible with industry-standard dual comparators like LM393?
No. APX393SG-13 uses SOP-8L pinout: OUTA, INA−, INA+, V−, V+, INB−, INB+, OUTB. LM393DR uses SOIC-8 pinout: IN−A, IN+A, OUTA, V+, IN−B, IN+B, OUTB, V−. Pin assignments differ significantly; direct replacement requires PCB redesign or adapter.
