Product details
Overview
APX339TSG-13 from Diodes Incorporated is a quad low-voltage rail-to-rail input comparator with open-drain outputs, designed for battery-powered portable electronics operating from 2.5V to 5.5V supply. It delivers 240–350 µA total supply current, 200 mV max output saturation voltage at 4 mA sink, and 1.7–9 mV input offset voltage across temperature. Used in notebook power sequencing and PDA voltage monitoring circuits.
For engineers reviewing the APX339TSG-13 datasheet, APX339TSG-13 pinout, APX339TSG-13 application, or APX339TSG-13 equivalent, key selection criteria include rail-to-rail input range (V− +0.2 V to V+ −0.2 V), industrial temperature operation (−40°C to +85°C), TSSOP-14L package compatibility, and open-drain logic interfacing capability.
Technical Context
The APX339TSG-13 integrates four independent comparators on a single die using standard CMOS process technology. Each channel features rail-to-rail input common-mode range and open-drain output stage, enabling flexible pull-up configuration to diverse logic families (e.g., 1.8V, 3.3V, or 5V I/O domains).
It operates over 2.5V–5.5V supply with guaranteed performance at both 2.7V and 5V. Propagation delays are specified as low as 200 ns (TPLH/TPHL) under 100 mV input overdrive at 5V, supporting fast threshold detection in portable system power management and battery charge control loops.
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) systems without level-shifting. |
| Input Common-Mode Range | V− + 0.2 V to V+ − 0.2 V - enables direct sensing of signals near supply rails, e.g., battery voltage monitoring down to 0.2 V above ground. |
| Output Type | Open-drain - allows wired-OR logic, mixed-voltage interfacing, and external pull-up to any logic rail up to 5.5 V. |
| Supply Current (All Channels) | 240–350 µA at 5 V - enables multi-comparator functions in ultra-low-power wake-up or status monitoring circuits. |
| Output Saturation Voltage | ≤200 mV at ISINK = 4 mA - ensures reliable low-level logic recognition even under moderate load, critical for microcontroller interrupt inputs. |
| Input Offset Voltage | 1.7–9 mV - provides sufficient accuracy for battery end-of-charge detection and undervoltage lockout thresholds. |
| Propagation Delay | 200 ns (max) at 100 mV overdrive, 5 V - supports real-time response in fast-switching power path enable/disable decisions. |
Pinout & Package
TSSOP-14L package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, 1.2 mm max height, RoHS-compliant lead-free finish, green molding compound (no Br/Sb).
| 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 to V+ − 0.2 V. |
| 3 | INA+ | Non-inverting input of Comparator A - used for threshold reference or signal comparison. |
| 4 | INB− | Inverting input of Comparator B - shares same input voltage range and bias current specs as INA−. |
| 5 | INB+ | Non-inverting input of Comparator B - enables dual-threshold or window detection with shared V−/V+ rails. |
| 6 | OUTB | Open-drain output of Comparator B - independently controllable; supports asynchronous event signaling. |
| 7 | V− | Negative supply / ground reference - common return for all comparators and internal circuitry. |
| 8 | OUTC | Open-drain output of Comparator C - expands monitoring capability to three independent conditions. |
| 9 | INC− | Inverting input of Comparator C - supports third threshold comparison without additional ICs. |
| 10 | INC+ | Non-inverting input of Comparator C - configurable for rising/falling edge detection or hysteresis via feedback. |
| 11 | IND− | Inverting input of Comparator D - completes quad-channel set for full-system voltage supervision. |
| 12 | IND+ | Non-inverting input of Comparator D - enables fourth independent decision point (e.g., thermal warning + battery OK + charger detect + system reset). |
| 13 | OUTD | Open-drain output of Comparator D - drives dedicated interrupt line or LED indicator directly. |
| 14 | V+ | Positive supply input - powers all four comparators; accepts 2.5–5.5 V with no external regulation required. |
Key Features

Applications
| Battery Voltage Monitoring | Power Supply Sequencing |
|---|---|
Use Scenario: Real-time tracking of Li-ion cell voltage during charging/discharging cycles in portable medical devices. IC Role / Device Role / Timing Role: Quad comparator monitors four distinct thresholds: overvoltage, undervoltage, full-charge, and thermal fault flags. Use Value: Eliminates need for external ADC and firmware polling by delivering immediate hardware-level interrupt signals per condition. | Use Scenario: Controlled ramp-up of multiple voltage rails (e.g., 3.3 V, 1.8 V, 1.2 V) in FPGA-based embedded systems. IC Role / Device Role / Timing Role: Compares each rail's divided-down voltage against precision references to assert enable signals only after stable regulation. Use Value: Prevents latch-up and initialization failures by enforcing strict power-up order without microcontroller involvement. |
| Portable Device Wake-Up Logic | USB-C Power Delivery Supervision |
Use Scenario: Detecting button press, lid open, or ambient light change to wake a tablet from deep sleep mode. IC Role / Device Role / Timing Role: One comparator channel monitors mechanical switch closure; others monitor sensor outputs (e.g., photodiode, accelerometer). Use Value: Reduces system standby current to sub-µA levels while maintaining responsive wake capability across multiple stimuli. | Use Scenario: Validating VBUS presence, CC line state, and PD contract negotiation success in USB-C host ports. IC Role / Device Role / Timing Role: Four comparators independently verify 5 V, 9 V, 15 V, and 20 V PD profiles against reference dividers. Use Value: Enables safe, autonomous voltage selection and fault isolation before connecting downstream loads or enabling converters. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM339DR | Higher supply current (500 µA typical), wider supply range (2–36 V), no rail-to-rail input, SOIC-14 package. | Less suitable for low-voltage battery systems; better for industrial 12/24 V supplies with legacy design reuse. | Select if existing board layout uses SOIC-14 and system voltage exceeds 5.5 V. |
| TLV339IPWR | Lower supply current (120 µA), rail-to-rail input, but only dual-channel; TSSOP-8 package. | Requires two ICs to match APX339's quad functionality; better for space-constrained dual-threshold designs. | Select when minimizing power dominates channel count, and PCB area permits two smaller packages. |
Compared with LM339DR and TLV339IPWR, APX339TSG-13 uniquely balances quad-channel density, rail-to-rail input operation, and sub-350 µA total supply current in a TSSOP-14L footprint-making it optimal for next-generation portable electronics where voltage headroom and battery life are constrained.

FAQ
Can APX339TSG-13 operate from a single 3.0 V lithium coin cell?
Yes. The APX339TSG-13 is fully specified from 2.5 V to 5.5 V, with guaranteed performance at 2.7 V and 5 V. At 3.0 V, its input common-mode range extends from 0.2 V to 2.8 V, and supply current remains within 240–300 µA, making it compatible with CR2032 and similar primary cells in low-duty-cycle monitoring applications.
Does APX339TSG-13 require external hysteresis resistors?
No mandatory requirement. The device has no built-in hysteresis, but external positive feedback can be added to any comparator input pair using two resistors. This is commonly done on INA+/INA− to prevent chatter near threshold crossings in noisy environments like motor-driven portable tools.
What is the maximum sink current per output of APX339TSG-13?
Each open-drain output is rated for 10–60 mA sink current depending on supply voltage and output voltage. At V+ = 5 V and VO ≤ 1.5 V, the minimum guaranteed sink current is 10 mA; typical performance reaches 60 mA. For reliable 3.3 V logic interfacing, a 10 kΩ pull-up yields ~0.33 mA load - well within specification.
Is the TSSOP-14L package of APX339TSG-13 compatible with standard reflow profiles?
Yes. The APX339TSG-13 uses a lead-free, RoHS-compliant finish and green molding compound. Its thermal profile aligns with IPC/JEDEC J-STD-020D for MSLE Level 3, supporting peak reflow temperatures up to 260°C for ≤40 seconds, compatible with standard lead-free assembly lines.
