Product details
Overview
The MAX9095ASD+T from Maxim Integrated is a quad, low-voltage, open-drain comparator with internal 2mV hysteresis, operating from +1.8V to +5.5V supply, featuring 100ns propagation delay, 120mV output saturation voltage at 4mA sink, and -40°C to +125°C automotive temperature range-used in battery-powered portable devices for precision threshold detection.
For engineers reviewing the MAX9095ASD+T datasheet, MAX9095ASD+T pinout, MAX9095ASD+T application, or MAX9095ASD+T equivalent, key selection criteria include guaranteed hysteresis, rail-to-rail input common-mode range including ground, low 250–400µA total supply current, and SO-14 package compatibility with legacy LMX339H designs.
Technical Context
The MAX9095ASD+T implements a BiCMOS quad comparator architecture with independent open-drain outputs, each capable of sinking up to 35mA. Its input stage supports common-mode voltages from -0.1V to VDD – 0.8V, eliminating phase reversal under overdrive conditions.
Internal 2mV hysteresis is fixed and non-adjustable, providing deterministic noise immunity without external components. Propagation delay remains stable across 10mV–100mV input overdrive and 1.8V–5.5V supply, with typical tPHL/tPLH of 50/100ns at 100mV overdrive and VDD = 5V.

Applications
| Battery Fuel Gauging | Motor Overcurrent Protection |
|---|---|
Use Scenario: Monitoring cell voltage and current-sense amplifier output in lithium-ion battery packs to trigger charge termination or discharge cutoff. IC Role / Device Role / Timing Role: Quad comparator provides independent high/low voltage thresholds and overcurrent detection with hysteresis to prevent oscillation near trip points. Use Value: Internal 2mV hysteresis ensures stable flag generation despite PCB trace noise and thermal drift, reducing firmware polling overhead. | Use Scenario: Detecting excessive current in BLDC motor phase legs using shunt resistor feedback, initiating immediate gate shutdown. IC Role / Device Role / Timing Role: Comparator B and C monitor complementary current paths; open-drain outputs drive MOSFET gate drivers directly via pull-up. Use Value: 100ns propagation delay enables sub-microsecond fault response, protecting IGBTs from destructive short-circuit energy. |
| Industrial Sensor Interface | Power Supply Sequencing |
Use Scenario: Converting analog outputs from pressure, temperature, or proximity sensors into clean digital logic signals for microcontroller GPIO. IC Role / Device Role / Timing Role: Comparator A and D compare sensor outputs against precision references; rail-to-rail inputs accept 0–2.5V sensor spans directly. Use Value: Input common-mode range extending to -0.1V allows grounding of sensor return paths without error from input bias current mismatch. | Use Scenario: Verifying correct ramp-up order and voltage stability of multi-rail power supplies (e.g., 1.2V core, 3.3V I/O, 5V analog) before enabling downstream logic. IC Role / Device Role / Timing Role: Each comparator monitors one rail against a dedicated reference; outputs feed AND-gate logic to generate global "POWER_GOOD" signal. Use Value: Low 250µA supply current per device minimizes loading on auxiliary bias rails used for sequencing supervision. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad open-drain comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMX339HSD/NOPB | Pin-compatible but no internal hysteresis; higher 1.5mV max offset; 300ns typical propagation delay | Requires external hysteresis resistors for noise immunity; less suitable for slow-moving sensor signals | Select when cost sensitivity outweighs need for integrated noise immunity and speed |
| TLV3704IPW | Lower 65µA/channel supply current; rail-to-rail inputs; no internal hysteresis; 1.5µs propagation delay | Optimized for ultra-low-power battery monitoring but lacks fast response for fault detection | Prefer for multi-year coin-cell applications where speed is secondary to quiescent current |
Compared with LMX339HSD/NOPB, MAX9095ASD+T delivers 5× faster response and built-in hysteresis, reducing BOM count; versus TLV3704IPW, it trades 3× higher supply current for 15× lower propagation delay-critical in safety-critical overvoltage detection.

FAQ
What is the maximum sink current capability of each output in MAX9095ASD+T?
Each open-drain output of the MAX9095ASD+T can sink up to 35mA while maintaining output saturation voltage ≤400mV at +125°C. At room temperature and 4mA load, VSAT is typically 120mV-enabling robust interfacing with standard 3.3V or 5V logic pull-ups without additional buffering.
Does MAX9095ASD+T require external hysteresis resistors for noise immunity?
No. The MAX9095ASD+T integrates 2mV of internal hysteresis specifically for the MAX9093/MAX9095 variants, eliminating the need for external positive-feedback components. This fixed hysteresis stabilizes output transitions on slow-moving or noisy inputs-such as thermistor readings or motor current ramps-without design overhead.
Can MAX9095ASD+T operate from a 1.8V supply while maintaining full specifications?
Yes. The MAX9095ASD+T is fully specified from +1.8V to +5.5V supply. At 1.8V, it delivers 6.4mA sink current, 56mV output saturation (1mA load), and maintains 1.5µV/°C input offset drift-making it suitable for modern ultra-low-voltage IoT sensor nodes and wearables where supply headroom is minimal.
What is the input common-mode voltage range of MAX9095ASD+T?
The input common-mode voltage range of MAX9095ASD+T extends from -0.1V below VSS to VDD – 0.8V. This rail-to-rail capability-including ground-allows direct connection to 0V-referenced sources like current-shunt amplifiers or resistive sensors without level-shifting circuitry, simplifying front-end design and improving accuracy.
Is MAX9095ASD+T pin-compatible with any industry-standard comparators?
Yes. The MAX9095ASD+T is a pin-for-pin compatible replacement for the LMX339H in the 14-pin SO package. It retains identical pinout, supply connections, and output configuration-allowing drop-in upgrades to gain internal hysteresis, faster propagation delay (100ns vs. 300ns), and wider supply range (+1.8V to +5.5V vs. +2.0V to +36V).
