Product details
Overview
The MAX9092AUA+T from Maxim Integrated is a dual, general-purpose, low-voltage comparator in an 8-pin µMAX package, featuring open-drain outputs, 1.8V to 5.5V single-supply operation, -40°C to +125°C automotive temperature range, and 100ns propagation delay at 100mV overdrive - used for precision threshold detection in battery-powered portable electronics.
For engineers reviewing the MAX9092AUA+T datasheet, MAX9092AUA+T pinout, MAX9092AUA+T application, or MAX9092AUA+T equivalent, key selection criteria include supply current (130–200µA per channel), input offset voltage (0.4–9mV), output saturation voltage (120–700mV), and compatibility with LM393/LM339 replacements in space-constrained designs.
Technical Context
The MAX9092AUA+T implements a BiCMOS comparator core optimized for low-voltage operation down to +1.8V, with rail-to-rail input common-mode range extending 0.1V below VSS and up to VDD – 0.8V. Its open-drain outputs support flexible pull-up configurations and wired-OR logic interfacing.
No phase reversal occurs under overdriven inputs, and internal design ensures stable operation across ±3.6V differential input voltage and 6V absolute maximum supply. It lacks internal hysteresis (unlike MAX9093/MAX9095), requiring external hysteresis networks for noisy signal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V - supports direct connection to Li-ion, 3.3V, and 5V rails without level-shifting. |
| Propagation Delay | 100ns (tPLH/tPHL @ 100mV overdrive) - enables reliable response to fast analog transitions in real-time monitoring. |
| Input Offset Voltage | 0.4mV (typ), ≤9mV (max over -40°C to +125°C) - ensures accurate threshold detection in precision sensing applications. |
| Supply Current | 130–200µA per channel (@ VDD = 5V, TA = +25°C) - enables multi-channel operation in ultra-low-power battery systems. |
| Output Saturation Voltage | 120mV (ISINK ≤ 4mA, TA = +25°C) - minimizes voltage drop when driving logic-level loads or MOSFET gates. |
| Input Common-Mode Range | -0.1V to VDD – 0.8V - allows ground-referenced inputs and compatibility with single-ended sensor outputs. |
| PSRR | 60–90dB (VDD = 1.8V–5.5V) - maintains stable trip points despite supply ripple in noisy power domains. |
Pinout & Package
Package: 8-pin µMAX (U8+1), 3mm × 3mm, 0.65mm pitch, RoHS-compliant, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Open-drain output of Comparator A - requires external pull-up; sinks up to 10–35mA for direct logic interfacing. |
| 2 | INA− | Inverting input of Comparator A - accepts signals within -0.1V to VDD – 0.8V; no phase reversal on overdrive. |
| 3 | INA+ | Noninverting input of Comparator A - matches INA− in common-mode range and bias current performance. |
| 4 | VSS | Negative supply terminal - connect directly to system ground; serves as reference for all inputs and outputs. |
| 5 | INB+ | Noninverting input of Comparator B - independent channel; identical electrical specs to INA+. |
| 6 | INB− | Inverting input of Comparator B - matched to INB+; supports differential or single-ended configuration. |
| 7 | OUTB | Open-drain output of Comparator B - electrically isolated from OUTA; enables dual independent decision paths. |
| 8 | VDD | Positive supply terminal - powers both comparators; bypass with 0.1µF capacitor near pin for noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input range including ground | Enables direct interface with ground-referenced sensors (e.g., thermistors, resistive bridges) without level shifters. |
| No phase reversal under overdrive | Prevents erroneous output toggling when inputs exceed common-mode limits - critical for fault-detection circuits. |
| Low 120mV output saturation voltage | Reduces power loss and improves noise margin when driving CMOS inputs or low-threshold MOSFETs. |
| Guaranteed operation from +1.8V | Supports direct integration into modern ultra-low-voltage microcontroller subsystems (e.g., wake-up comparators). |
| Automotive-grade temperature range | Validated for continuous operation from -40°C to +125°C - suitable for under-hood and industrial control modules. |
Applications

Use Value: Open-drain outputs allow wired-OR reset generation; rail-to-rail inputs simplify sensing across multiple voltage domains. |
| Industrial Sensor Threshold Detection | USB-C Power Delivery Status Monitoring |
Use Scenario: Converting analog output from a 4–20mA loop-powered pressure sensor into digital alarm signals. IC Role / Device Role / Timing Role: Comparator A detects high-pressure limit; Comparator B detects low-pressure limit - both referenced to precision voltage dividers. Use Value: Input offset <9mV ensures sub-0.5% full-scale error; PSRR >60dB rejects switching noise from adjacent SMPS. |
Use Scenario: Monitoring CC1/CC2 line voltages during USB-C cable insertion to determine orientation and source capability. IC Role / Device Role / Timing Role: One comparator detects VCONN presence (>2.7V); the other validates Rp/Rd resistor identification voltage levels. Use Value: 100ns propagation delay enables fast orientation detection; 1.8V operation supports direct interface with USB-C controller I/O rails. |
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 |
|---|---|---|---|
| LM393DR | Higher supply current (500µA), wider offset (±7mV), no guaranteed 1.8V operation, SO-8 only. | Lacks automotive temp range and low-voltage support; suitable for cost-sensitive non-automotive consumer boards. | Select LM393DR only if 5V-only operation and lower unit cost outweigh need for extended temperature and low-power performance. |
| TLV3702IDR | Lower supply current (80µA typ), rail-to-rail outputs, but no open-drain; 1.8V min, -40°C to +125°C, SO-8. | Push-pull output prevents wired-OR use; better for driving ADC reference or logic directly without pull-ups. | Choose TLV3702IDR when push-pull drive and lowest quiescent current are prioritized over open-drain flexibility. |
Compared with LM393DR and TLV3702IDR, the MAX9092AUA+T uniquely combines open-drain outputs, guaranteed 1.8V operation, automotive temperature rating, and sub-200µA supply current - making it optimal for space-constrained, battery-critical, and industrial-grade dual-threshold detection.

FAQ
What is the operating supply voltage range for the MAX9092AUA+T?
The MAX9092AUA+T operates from +1.8V to +5.5V on a single supply. This range is fully specified and guaranteed across the entire -40°C to +125°C temperature range, enabling direct use with Li-ion batteries, 3.3V logic rails, and legacy 5V systems without external regulation.
Does the MAX9092AUA+T include internal hysteresis?
No, the MAX9092AUA+T does not include internal hysteresis. Internal 2mV hysteresis is exclusive to the MAX9093 and MAX9095 variants. For noise immunity, external hysteresis must be added using positive feedback resistors - a standard practice confirmed in the MAX9092AUA+T datasheet Application Information section.
What package type is used for the MAX9092AUA+T?
The MAX9092AUA+T uses the 8-pin µMAX package (package code U8+1), measuring 3mm × 3mm with 0.65mm lead pitch. It is RoHS-compliant, features an exposed thermal pad (non-electrical), and is pin-compatible with the SOT23 variant (MAX9092AKA+) but offers improved thermal performance.
Can the MAX9092AUA+T drive standard CMOS logic inputs directly?
Yes - the MAX9092AUA+T's open-drain outputs can drive standard CMOS inputs when paired with an appropriate pull-up resistor (typically 1kΩ–10kΩ to VDD). At ISINK ≤ 4mA, the output saturation voltage remains ≤120mV at +25°C, ensuring robust LOW-level logic compatibility across voltage rails.
Is the MAX9092AUA+T suitable for automotive applications?
Yes - the MAX9092AUA+T is qualified for the -40°C to +125°C automotive temperature range and specified across this range for all key parameters (offset, propagation delay, supply current). It meets AEC-Q100 stress test requirements as documented in Maxim's official product documentation.
