Product details
Overview
MAX9092AUA+ from Maxim Integrated is a dual-channel, low-voltage, open-drain comparator IC in an 8-pin µMAX package, operating from +1.8V to +5.5V with 100ns propagation delay, 7mV max input offset voltage, and -40°C to +125°C automotive temperature range-used for precision threshold detection in battery-powered portable electronics.
For engineers reviewing the MAX9092AUA+ datasheet, MAX9092AUA+ pinout, MAX9092AUA+ application, or MAX9092AUA+ equivalent, key selection criteria include supply current (130–300µA over temperature), input common-mode range extending to ground, no phase reversal under overdrive, 120mV output saturation voltage at 4mA sink, and compatibility with LM393-style designs.
Technical Context
The MAX9092AUA+ implements a dual-comparator architecture with rail-to-rail input capability (VCM = -0.1V to VDD – 0.8V), open-drain outputs requiring external pull-up, and no internal hysteresis-distinguishing it from the hysteresis-equipped MAX9093/MAX9095 variants. It uses BiCMOS process technology for low input bias current (±0.027nA typ) and high PSRR (90dB).
Its propagation delay is specified at 50–120ns depending on overdrive (10mV to 100mV) and temperature, with guaranteed operation across full automotive temperature range and supply voltages down to +1.8V-enabling use in ultra-low-power sensor monitoring and power-rail supervision circuits where deterministic timing and noise immunity are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V - supports single-cell Li-ion, 3.3V, and 5V systems without level shifting. |
| Propagation Delay (tPLH/tPHL) | 50ns to 120ns - enables reliable response to fast transients in power sequencing and fault detection. |
| Input Offset Voltage (VOS) | 0.4mV (typ), 7mV (max) - ensures accurate threshold detection with minimal calibration overhead. |
| Supply Current per Channel | 130–300µA over -40°C to +125°C - enables always-on monitoring in battery-critical applications. |
| Output Saturation Voltage (VSAT) | 120mV at ISINK = 4mA - allows clean logic-level interfacing with 1.8V/3.3V microcontrollers via pull-up. |
| Input Common-Mode Range | -0.1V to VDD – 0.8V - supports ground-referenced inputs and rail-to-rail sensing without clamping diodes. |
| Operating Temperature | -40°C to +125°C - qualified for under-hood automotive, industrial control, and extended-life portable devices. |
Pinout & Package
MAX9092AUA+ is housed in an 8-pin µMAX® package (package code U8+1), 3mm × 3mm, 0.5mm pitch, exposed pad for thermal enhancement. Pinout matches LM393-compatible dual-comparator footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Open-drain output of Comparator A - requires external pull-up; sinks up to 35mA for direct LED or MOSFET gate drive. |
| 2 | INA− | Inverting input of Comparator A - accepts signals down to -0.1V; no phase reversal when overdriven. |
| 3 | INA+ | Noninverting input of Comparator A - supports rail-to-rail common-mode range including ground reference. |
| 4 | VSS | Negative supply terminal - connect directly to system ground; serves as return path for all inputs and outputs. |
| 5 | INB+ | Noninverting input of Comparator B - electrically isolated from INA+; enables independent dual-threshold sensing. |
| 6 | INB− | Inverting input of Comparator B - matched offset and bias performance to INA− for consistent dual-channel behavior. |
| 7 | OUTB | Open-drain output of Comparator B - independently controllable; supports wired-OR logic or separate load switching. |
| 8 | VDD | Positive supply input - accepts 1.8V–5.5V; bypassing with 0.1µF capacitor near pin is mandatory for stability. |
Key Features
| Feature | Design Value |
|---|---|
| No phase reversal on overdrive | Prevents false triggering when input exceeds common-mode limits - critical for undervoltage lockout and surge detection. |
| Guaranteed 1.8V operation | Enables direct interface with modern ultra-low-voltage MCUs and sensors without supply translation circuitry. |
| Low 65µA/channel supply current at 5V | Reduces quiescent power in always-on battery monitors - extends shelf life of medical and IoT edge devices. |
| Input common-mode range includes ground | Allows direct connection of 0V-referenced sensors (e.g., thermistors, current shunts) without level-shifting resistors. |
| Open-drain outputs with 35mA sink capability | Supports flexible logic interfacing (1.8V/3.3V/5V), LED driving, and direct control of N-channel MOSFET gates. |
Applications
| Battery Voltage Monitor | Power-Rail Sequencing Supervisor |
|---|---|
|
Use Scenario: Monitoring lithium-ion cell voltage during charging/discharging to trigger cutoff or alert at 2.8V and 4.2V thresholds. IC Role / Device Role / Timing Role: Dual comparator providing independent high- and low-voltage trip points with precise hysteresis-free decision logic. Use Value: Eliminates need for external reference dividers or op-amp buffers due to rail-to-rail input and ground-sensing capability. |
Use Scenario: Ensuring correct power-up order of multiple rails (e.g., 1.2V core before 3.3V I/O) in FPGA or SoC systems. IC Role / Device Role / Timing Role: Two independent comparators monitor each rail against precision references, asserting reset signals only when both are valid. Use Value: Achieves sub-100ns response to rail collapse, preventing latch-up or configuration corruption during brownout events. |
| Portable Device Low-Power Wake-Up | Industrial Sensor Threshold Detector |
|
Use Scenario: Detecting button press or motion-triggered signal from ultra-low-power accelerometer to wake sleeping MCU. IC Role / Device Role / Timing Role: Comparator A triggers wake-up on rising edge; Comparator B validates debounce window using timed reference. Use Value: Draws only 130µA total at 1.8V - extends coin-cell battery life to >1 year in standby with periodic wake-ups. |
Use Scenario: Converting analog output from pressure or temperature sensor into digital alarm signal for PLC input. IC Role / Device Role / Timing Role: Dual comparator provides high/low limit detection with independent hysteresis (via external resistors) to suppress noise-induced chatter. Use Value: Input bias current <0.03nA avoids loading high-impedance sensor bridges; 125°C rating supports harsh-environment deployment. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM393DR | Wider supply range (2–36V), higher input offset (7mV typ), 300ns propagation delay, no guaranteed 1.8V operation. | Preferred for industrial 24V systems; unsuitable for sub-2V battery monitoring or fast-response fault detection. | Select LM393DR only if operating above 2.5V and timing >300ns is acceptable. |
| TLV3702IDR | Lower supply current (800nA typ), rail-to-rail output, but no open-drain - requires level-shifting for mixed-voltage interfaces. | Better for nanowatt sensor nodes; incompatible with wired-OR bus architectures or direct LED drive. | Choose TLV3702IDR when ultra-low IQ dominates design priority and open-drain functionality is not required. |
Compared with LM393DR and TLV3702IDR, the MAX9092AUA+ uniquely balances 1.8V operation, 100ns speed, open-drain flexibility, and automotive temperature support - making it optimal for compact, battery-sensitive, and timing-critical dual-threshold detection.

FAQ
What is the maximum sink current capability of each output in MAX9092AUA+?
Each open-drain output of the MAX9092AUA+ can sink up to 35mA when VOUT ≤ 1.5V, as specified in the DC Electrical Characteristics table at TA = +25°C. This allows direct driving of LEDs, small relays, or N-channel MOSFET gates without external buffer stages - a key advantage over legacy comparators like LM393 that specify only 6mA.
Does MAX9092AUA+ include internal hysteresis?
No, the MAX9092AUA+ does not include internal hysteresis. Internal 2mV hysteresis is exclusive to the MAX9093/MAX9095 variants. The MAX9092AUA+ is intended for applications where external hysteresis control is preferred - for example, when custom threshold windows are needed or when hysteresis must scale with supply voltage using resistor networks.
Can MAX9092AUA+ operate from a 1.8V supply while maintaining full specifications?
Yes, the MAX9092AUA+ is fully specified and guaranteed to operate from +1.8V to +5.5V. At 1.8V, it delivers 120ns propagation delay (tPLH), 56mV output saturation voltage at 1mA sink, and 120µA total supply current - enabling direct integration with modern ultra-low-voltage microcontrollers and sensors without voltage translation.
What is the input common-mode voltage range for MAX9092AUA+?
The input common-mode voltage range for MAX9092AUA+ is -0.1V to VDD – 0.8V, explicitly including ground (0V). This allows direct connection of ground-referenced sources such as current-sense amplifiers, thermistor dividers, or battery terminals - eliminating the need for level-shifting circuitry and reducing BOM count and board area.
Is MAX9092AUA+ pin-compatible with LM393?
Yes, the MAX9092AUA+ is pin-for-pin compatible with the LM393 in its 8-pin µMAX package, matching the same pinout: OUTA, INA−, INA+, VSS, INB+, INB−, OUTB, VDD. This enables drop-in replacement in existing LM393-based designs while delivering lower supply current, faster propagation delay, and guaranteed 1.8V operation - without PCB layout changes.
