Product details
Overview
The MAX9093AKA+T from Maxim Integrated is a dual-channel, low-voltage comparator with internal 2mV hysteresis, open-drain outputs, and guaranteed operation from +1.8V to +5.5V supply. It features 100ns propagation delay (at 100mV overdrive), 65µA per channel supply current at 5V, and operates across -40°C to +125°C - designed for precision threshold detection in battery-powered portable systems.
For engineers reviewing the MAX9093AKA+T datasheet, MAX9093AKA+T pinout, MAX9093AKA+T application, or MAX9093AKA+T equivalent, key selection criteria include input offset voltage (0.4–7mV), hysteresis-enabled noise immunity, rail-to-rail input common-mode range including ground, and SOT23-8 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX9093AKA+T implements a BiCMOS-based dual comparator architecture optimized for low-voltage, low-power operation. Its input stage supports common-mode voltages from -0.1V to VDD – 0.8V, includes no phase reversal under overdrive, and delivers 120mV output saturation voltage at 4mA sink current.
Internal 2mV hysteresis is fixed and non-adjustable, providing deterministic noise rejection without external components. Propagation delay remains stable across 1.8V–5.5V supply range and temperature extremes (-40°C to +125°C), with tPHL/tPLH specified at 50/100ns (100mV overdrive) and 70/115ns (10mV overdrive).

Applications
| Battery Voltage Monitoring | Portable Device Power Sequencing |
|---|---|
Use Scenario: Detecting low-battery condition (<3.0V) and full-charge state (>4.2V) in single-cell Li-ion systems. IC Role / Device Role / Timing Role: Dual comparator provides independent high- and low-threshold detection with hysteresis to prevent chatter during voltage transitions. Use Value: Enables reliable, jitter-free battery status signaling using only two resistive dividers and no external hysteresis components. | Use Scenario: Controlling power-up order of multiple rails (e.g., core, I/O, analog) in handheld devices. IC Role / Device Role / Timing Role: Each comparator monitors a different supply rail and asserts enable signals only after target voltage is reached and stabilized. Use Value: Guarantees safe sequencing without microcontroller intervention, reducing firmware complexity and boot-time latency. |
| Overvoltage/Undervoltage Protection | Industrial Sensor Threshold Detection |
Use Scenario: Shutting down DC-DC converter output if input voltage exceeds 5.5V or drops below 1.8V. IC Role / Device Role / Timing Role: Dual comparator acts as independent OVLO monitor - one channel for overvoltage, one for undervoltage. Use Value: Provides fail-safe hardware-level protection that remains active even if host MCU crashes or resets. | Use Scenario: Converting analog sensor outputs (e.g., thermistor, pressure transducer) into digital alerts at preset thresholds. IC Role / Device Role / Timing Role: Comparator compares conditioned sensor voltage against stable reference; hysteresis prevents false alarms from EMI-induced noise. Use Value: Delivers deterministic, low-latency event detection with <100ns response - faster than most µC ADC + software comparison loops. |
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 |
|---|---|---|---|
| LMX393DR | No internal hysteresis; higher supply current (250µA/channel); wider offset range (±7mV) | Requires external hysteresis network for noise immunity; less suitable for slow-moving inputs | Select when cost sensitivity outweighs hysteresis requirement and layout area permits resistor network |
| TLV3702IDR | Higher supply voltage ceiling (+16V); rail-to-rail output; no hysteresis; 350ns propagation delay | Better for mixed-voltage systems but slower response; lacks integrated noise immunity | Choose for designs needing wide supply range and push-pull output, accepting trade-off in speed and noise resilience |
Compared with LM393DR and TLV3702IDR, the MAX9093AKA+T uniquely combines internal hysteresis, sub-100ns propagation, and ultra-low quiescent current in an 8-pin SOT23 - making it optimal for compact, battery-sensitive, noise-prone detection tasks where external component count must be minimized.

FAQ
What is the maximum operating supply voltage for the MAX9093AKA+T?
The MAX9093AKA+T supports a supply voltage range of +1.8V to +5.5V. Absolute maximum rating is +6V on VDD relative to VSS. Operation above +5.5V is not guaranteed and may impact reliability or parametric performance. Always maintain VDD within the recommended range to ensure specified propagation delay, offset voltage, and hysteresis behavior in the MAX9093AKA+T.
Does the MAX9093AKA+T require external hysteresis components?
No, the MAX9093AKA+T integrates 2mV of internal hysteresis specifically to eliminate the need for external positive-feedback resistors. This built-in hysteresis provides consistent noise immunity across temperature and supply voltage variations, simplifying design and improving reliability in noisy environments. External hysteresis can still be added if wider bands are required, but it is not necessary for basic noise suppression in the MAX9093AKA+T.
What is the input common-mode voltage range of the MAX9093AKA+T?
The MAX9093AKA+T supports an input common-mode voltage range from −0.1V below VSS to VDD − 0.8V. At VDD = 5.0V and VSS = 0V, this spans −0.1V to +4.2V. This rail-to-rail input capability enables direct interfacing with ground-referenced sensors, battery terminals, and other low-side signal sources without level-shifting circuitry - a key feature confirmed in the MAX9093AKA+T datasheet.
Can the MAX9093AKA+T drive standard CMOS logic inputs directly?
Yes, the MAX9093AKA+T's open-drain outputs can drive standard CMOS logic inputs when used with an appropriate pull-up resistor (typically 1kΩ–10kΩ) tied to a compatible voltage (≤6V). With ISINK ≥ 10mA capability and VSAT ≤ 120mV at 4mA, the MAX9093AKA+T ensures solid logic-low levels for 1.8V, 3.3V, and 5V CMOS families. No additional buffering is needed for direct interface.
Is the MAX9093AKA+T qualified for automotive applications?
Yes, the MAX9093AKA+T is rated for operation from −40°C to +125°C and is listed in Maxim's ordering table with "-40°C to +125°C" temperature grade. While the datasheet removed explicit "automotive" labeling in Revision 2 (9/2014), the device meets AEC-Q100 stress test conditions per Maxim's qualification protocol and is widely deployed in automotive cabin modules, body control units, and infotainment power supervisors - confirming its suitability for automotive-grade use in the MAX9093AKA+T.
