Product details
Overview
The MAX9093AUA+ from Maxim Integrated is a dual-channel, low-voltage comparator with internal 2mV hysteresis, open-drain outputs, and operation from +1.8V to +5.5V. It features 100ns propagation delay (100mV overdrive), 65µA per channel supply current at 5V, and input common-mode range extending to ground-designed for precision threshold detection in battery-powered portable systems.
For engineers reviewing the MAX9093AUA+ datasheet, MAX9093AUA+ pinout, MAX9093AUA+ application, or MAX9093AUA+ equivalent, key selection criteria include guaranteed automotive temperature range (–40°C to +125°C), noise-immune hysteresis, rail-to-rail input capability, and SOT23/μMAX package compatibility with space-constrained PCB layouts.
Technical Context
The MAX9093AUA+ implements a BiCMOS process-based dual comparator architecture with internally trimmed hysteresis to eliminate oscillation on slow or noisy inputs. Its input stage supports common-mode voltages down to –0.1V (below VSS) and up to VDD – 0.8V, enabling direct interfacing with ground-referenced sensors and logic-level signals.
Each comparator delivers open-drain output capable of sinking ≥10mA at VOUT ≤ 1.5V, with low saturation voltage (120mV at ISINK = 4mA) and high PSRR (60–90dB across 1.8V–5.5V supply). Propagation delay remains stable across temperature (–40°C to +125°C) and supply voltage variations, supporting reliable timing-critical decision-making.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V - enables direct use with Li-ion, coin-cell, and 3.3V/5V logic rails |
| Propagation Delay | 100ns (tPLH/tPHL, 100mV overdrive) - supports >1MHz signal monitoring without timing uncertainty |
| Input Offset Voltage | 0.4mV (typ), 7mV (max) - ensures accurate threshold detection with minimal calibration overhead |
| Hysteresis | 2mV (internal, fixed) - eliminates false triggering on EMI-prone or slowly ramping sensor outputs |
| Supply Current | 130µA (typ, both channels at +25°C, VDD = 5V) - extends battery life in always-on monitoring circuits |
| Input Common-Mode Range | –0.1V to VDD – 0.8V - allows direct connection to ground-referenced transducers and ADC references |
| Output Sink Current | 10mA (min, VOUT ≤ 1.5V) - drives standard pull-up resistors and logic inputs without external buffers |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial, and extended-environment applications |
Pinout & Package
MAX9093AUA+ uses an 8-pin μMAX® package (pin-compatible with SOT23), measuring 3mm × 3mm × 0.8mm with exposed pad for thermal enhancement. The package is RoHS-compliant and optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Open-drain output of Comparator A - requires external pull-up; compatible with I²C, SMBus, and mixed-voltage logic |
| 2 | INA− | Inverting input of Comparator A - accepts signals down to –0.1V (below VSS) for true ground-referenced sensing |
| 3 | INA+ | Noninverting input of Comparator A - supports rail-to-rail common-mode range for flexible reference configuration |
| 4 | VSS | Negative supply terminal (GND) - serves as return path for both comparators and output sinks |
| 5 | INB+ | Noninverting input of Comparator B - electrically isolated from INA±; enables independent dual-threshold detection |
| 6 | INB− | Inverting input of Comparator B - shares same input specs as INA±, including no phase reversal on overdrive |
| 7 | OUTB | Open-drain output of Comparator B - independently controllable; supports wired-OR logic and fault-bus architectures |
| 8 | VDD | Positive supply input (+1.8V to +5.5V) - powers both comparators; bypass capacitor required at pin for noise immunity |
Key Features

Applications
| Mobile Power Supervision | Notebook Battery Monitoring |
|---|---|
Use Scenario: Detecting low-battery cutoff thresholds and charger-insertion events in smartphones and wearables. IC Role / Device Role / Timing Role: Dual comparator performs simultaneous undervoltage lockout (UVLO) and charge-status flag generation with hysteresis to reject ripple-induced chatter.

Use Value: Rail-to-rail input range allows direct connection to 0–3.3V sensor outputs without level-shifting, reducing component count. |
| Industrial Sensor Interface | Automotive Cabin Control |
Use Scenario: Converting analog pressure or proximity sensor outputs into digital presence/absence signals for PLC input modules. IC Role / Device Role / Timing Role: Comparator A detects rising edge of 4–20mA loop-derived voltage; Comparator B validates signal validity via window comparison.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMX393H | No internal hysteresis; higher supply current (250µA typical); wider offset voltage range (±7mV) | Lacks noise immunity for slow-moving inputs; requires external hysteresis resistors in EMI-heavy environments | Select only if legacy LM393 footprint reuse is mandatory and system-level filtering is already implemented |
| TLV3702IDR | Lower supply current (55µA/ch), rail-to-rail output, but no internal hysteresis and narrower temp range (–40°C to +105°C) | Better for ultra-low-power designs but unsuitable for automotive under-hood or industrial high-temp zones | Prefer when battery life is paramount and ambient temperature stays below +105°C |
Compared with LMX393H and TLV3702IDR, the MAX9093AUA+ uniquely combines automotive-grade temperature support, built-in hysteresis, and μMAX packaging - delivering noise-immune dual-threshold detection without design compromises in space- or reliability-constrained systems.

FAQ
What is the maximum operating supply voltage for the MAX9093AUA+?
The MAX9093AUA+ supports a supply voltage range of +1.8V to +5.5V. Absolute maximum rating is +6V on VDD relative to VSS. Operation beyond +5.5V is not guaranteed and may impact long-term reliability or parametric performance - always limit VDD to ≤ +5.5V in final designs using MAX9093AUA+.
Does the MAX9093AUA+ require external hysteresis components?
No. The MAX9093AUA+ integrates 2mV of internal hysteresis, eliminating the need for external feedback resistors in most noise-sensitive applications. This feature is factory-trimmed and specified across –40°C to +125°C, making MAX9093AUA+ ideal for compact, high-reliability designs where board space and component count must be minimized.
Can the MAX9093AUA+ inputs safely operate below ground?
Yes. The MAX9093AUA+ input common-mode range extends to –0.1V below VSS (ground), allowing direct interfacing with slightly negative sensor outputs or AC-coupled signals without clamping diodes or level-shifters - a key advantage confirmed in the device's DC Electrical Characteristics table for MAX9093AUA+.
What is the output drive capability of the MAX9093AUA+?
The MAX9093AUA+ provides open-drain outputs rated for ≥10mA sink current at VOUT ≤ 1.5V (per channel), with typical output saturation voltage of 120mV at 4mA. This enables direct driving of standard 3.3V/5V logic inputs and LED indicators using common pull-up configurations - verified in the "DC Electrical Characteristics-5.0V Operation" section of the MAX9093AUA+ datasheet.
Is the MAX9093AUA+ pin-compatible with other packages in the MAX909x family?
Yes. The MAX9093AUA+ in 8-pin μMAX® shares identical pinout with the MAX9093AKA+ in 8-pin SOT23. Both are pin-for-pin replacements for the LMX393H, enabling seamless migration between μMAX and SOT23 footprints without PCB redesign - a key interoperability feature documented in the "Pin Configurations" section of the MAX9093AUA+ datasheet.
