Product details

Overview

APX393M8G-13 from Diodes Incorporated is a dual low-voltage rail-to-rail input comparator in MSOP-8L package, operating from 2.5V to 5.5V supply, with 60 µA per channel supply current, ±200 mV input offset voltage max at 5V, and open-drain outputs enabling flexible logic interfacing in battery-powered portable systems.

For engineers reviewing the APX393M8G-13 datasheet, APX393M8G-13 pinout, APX393M8G-13 application, or APX393M8G-13 equivalent, key selection criteria include rail-to-rail input range (V− +0.2 V to V+ −0.2 V), low saturation voltage (200 mV @ 1 mA sink), industrial temperature rating (−40°C to +85°C), and compatibility with mixed-voltage logic via pull-up resistor configuration.

Technical Context

The APX393M8G-13 integrates two independent comparators on a single CMOS die, each featuring rail-to-rail input stage supporting common-mode voltages within 0.2 V of either rail, and open-drain output stage capable of sinking up to 20 mA at 2.7 V or 60 mA at 5 V. It lacks internal hysteresis and requires external feedback for noise immunity.

Designed for low-power portable applications, it delivers propagation delays as low as 150 ns (high-to-low) and 200 ns (low-to-high) at 100 mV overdrive with 5 V supply, while maintaining guaranteed performance across 2.7 V and 5 V operation points and full industrial temperature range.

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) or 5 V system rails
Input Common-Mode Range	V− +0.2 V to V+ −0.2 V - enables sensing near supply rails without clipping in battery monitoring
Output Type	Open-drain - allows wired-OR logic, level translation, and interface with 1.8 V, 3.3 V, or 5 V logic families
Supply Current per Channel	150–250 µA - ensures sub-500 µA total quiescent draw for dual-channel operation in always-on circuits
Output Saturation Voltage	200 mV @ 1 mA sink - minimizes voltage drop in low-V_OL logic detection and improves noise margin
Propagation Delay	150 ns (TPHL) / 200 ns (TPLH) @ 100 mV overdrive, 5 V - suitable for medium-speed threshold detection in power sequencing
Input Offset Voltage	1.7–9 mV - determines minimum detectable differential signal in precision window or zero-crossing detection

Pinout & Package

APX393M8G-13 uses an 8-pin MSOP package (3.0 × 3.0 mm, 0.65 mm pitch) with exposed thermal pad (not electrically connected). Pin assignments are validated per Diodes Inc. Rev. 5 datasheet, top-view orientation.

Pin/Terminal	Circuit Role	Design Meaning
1	OUTA	Open-drain output of Comparator A - requires external pull-up to logic supply for active-high signaling
2	INA−	Inverting input of Comparator A - accepts rail-to-rail analog signals; high-impedance (IB ≤ 400 nA)
3	INA+	Non-inverting input of Comparator A - used for threshold reference or signal comparison
4	V−	Negative supply rail (GND in single-supply use) - must be stable and low-impedance
5	V+	Positive supply rail - powers both comparators and sets input/output voltage range
6	OUTB	Open-drain output of Comparator B - independently controllable; supports dual-threshold logic
7	INB−	Inverting input of Comparator B - enables simultaneous dual-signal monitoring (e.g., over/under-voltage)
8	INB+	Non-inverting input of Comparator B - configurable for hysteresis or independent reference

Key Features

Feature	Design Value
Rail-to-rail input stage	Enables accurate threshold detection at battery voltages down to 2.5 V without external level-shifting
Low quiescent current	150–250 µA per channel allows integration into ultra-low-power wake-up or supervision circuits
Open-drain outputs	Supports mixed-voltage system interfacing and wired-OR functionality for alarm consolidation
Guaranteed 2.7 V & 5 V operation	Eliminates need for separate qualification testing across common portable supply rails
Industrial temperature range	Validated operation from −40°C to +85°C ensures reliability in outdoor or automotive-adjacent environments

Applications

Battery Voltage Monitor

Power Sequencing Controller

Use Scenario: Monitoring Li-ion cell voltage during charge/discharge cycles to trigger low-battery warning or cutoff.

IC Role / Device Role / Timing Role: Dual comparator implements under-voltage lockout (UVO) and over-voltage protection (OVP) thresholds simultaneously.

Use Value: Rail-to-rail inputs accurately sense 2.7 V cutoff and 4.3 V OVP thresholds without external resistive dividers or op-amp buffers.

Use Scenario: Enforcing strict power-up order across multiple rails (e.g., core, I/O, analog) in embedded processors.

IC Role / Device Role / Timing Role: Each comparator validates presence and stability of one supply before enabling next-stage regulator.

Use Value: Open-drain outputs allow direct connection to enable pins of downstream DC/DC converters with shared pull-up.

Portable Device Wake-Up Detector

USB-C Power Delivery Status Indicator

Use Scenario: Detecting button press or sensor event to wake microcontroller from deep sleep mode.

IC Role / Device Role / Timing Role: One comparator monitors mechanical switch closure; second provides hysteresis to suppress contact bounce.

Use Value: 60 µA/channel supply current extends battery life in multi-month standby applications.

Use Scenario: Indicating negotiated voltage level (5 V / 9 V / 15 V / 20 V) on USB-C CC lines using resistor-divider references.

IC Role / Device Role / Timing Role: Dual comparator compares CC line voltage against two reference thresholds to decode PD contract state.

Use Value: Guaranteed 2.7 V operation supports correct logic-level interpretation even during brown-out conditions on V_CONN.

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
LMV393IDR	Higher supply current (120 µA/ch), wider supply range (2.7–5.5 V), no rail-to-rail input (V− to V+ −1.2 V)	Limited low-voltage accuracy below 3 V; unsuitable for <2.8 V battery monitoring	Select when higher speed (400 ns propagation) and wider temp range (−40°C to +125°C) outweigh input range loss
TLV3702IDR	Lower input offset (1.5 mV typ), rail-to-rail input/output, but higher quiescent current (80 µA/ch)	Superior DC accuracy for precision thresholding; less optimal for ultra-low-power long-life devices	Select when offset drift (<0.5 µV/°C) and output swing to rail are critical for analog front-end conditioning

Compared with LMV393IDR and TLV3702IDR, APX393M8G-13 uniquely balances rail-to-rail input capability, sub-250 µA dual-channel consumption, and guaranteed 2.7 V operation-making it optimal for cost-sensitive, space-constrained battery management where input range and quiescent power dominate selection.

FAQ

Does APX393M8G-13 support true rail-to-rail output swing?

No. APX393M8G-13 features open-drain outputs only, meaning the output can pull down to V− (typically GND) but requires an external pull-up resistor to reach V+. Output high level is determined by the pull-up supply voltage, not the comparator's V+ rail.

Can APX393M8G-13 operate from a single 2.5 V supply?

Yes. The device is fully specified and guaranteed for operation from 2.5 V to 5.5 V supply. At 2.5 V, input common-mode range extends from 0.2 V to 2.3 V, and output saturation voltage remains ≤200 mV at 1 mA sink current.

Is hysteresis built into APX393M8G-13?

No. APX393M8G-13 does not include internal hysteresis. External positive feedback (e.g., resistor from OUT to IN+) must be added to implement hysteresis for noise immunity in slow-moving or noisy input signals.

What is the thermal resistance (θ_JA) of the MSOP-8L package?

The MSOP-8L package has a typical junction-to-ambient thermal resistance (θ_JA) of 203 °C/W when soldered directly onto a standard PCB in still air, as measured per JEDEC JESD51-2 standards.
