Product details
Overview
MAX9039BEBT-T from Analog Devices is a micropower single-supply comparator with integrated 1.23V precision voltage reference, designed for battery-operated systems requiring rail-to-rail inputs/outputs, 40μA quiescent current, ±1mV input offset (B grade), and −40°C to +85°C operation in a 6-bump UCSP package.
For engineers reviewing the MAX9039BEBT-T datasheet, MAX9039BEBT-T pinout, MAX9039BEBT-T application, or MAX9039BEBT-T equivalent, this page delivers verified electrical parameters, UCSP package layout, B-grade reference accuracy (±0.4% initial, 100ppm/°C tempco), comparator hysteresis (±3mV), and real-world use cases in precision battery management and IR receivers.
Technical Context
The MAX9039BEBT-T integrates a single comparator with rail-to-rail input stage extending 250mV beyond supply rails and push-pull output capable of sinking/sourcing 8mA. Its internal hysteresis (±3mV) ensures clean switching on slow signals without external components.
The co-integrated 1.23V series-mode voltage reference uses curvature correction and laser-trimmed thin-film resistors, delivering ±0.4% initial accuracy (B grade), 100ppm/°C temperature coefficient, and stable operation with capacitive loads up to 4.7nF.
Key Specifications

|---|---|
| Supply Voltage Range | 2.5V to 5.5V - supports direct interface with 3V and 5V logic without level shifters |
| Quiescent Supply Current | 40μA at VCC = 5V - enables multi-year battery life in coin-cell-powered sensors |
| Reference Output Voltage | 1.230V (±0.4% at +25°C) - precise threshold for low-voltage battery monitoring |
| Input Offset Voltage | ±1mV (max, B grade, −40°C to +85°C) - ensures accurate trip-point stability across industrial temperature range |
| Propagation Delay | 400ns at 100mV overdrive - suitable for medium-speed signal detection in IR receivers |
| Common-Mode Input Range | VEE − 0.25V to VCC + 0.25V - allows direct sensing of signals below ground or above VCC |
| Output Drive Capability | Rail-to-rail push-pull, ±8mA - drives LEDs, logic inputs, or small MOSFET gates directly |

Applications
| Precision Battery Management | IR Receivers |
|---|---|

IC Role / Device Role / Timing Role: Comparator detects zero-crossings of filtered IR signal using internal hysteresis to reject noise. Use Value: 400ns propagation delay enables reliable detection of 38kHz pulses (26.3μs period) with margin. |
| Window Comparators | Level Translators |
Use Scenario: Validating analog sensor outputs (e.g., temperature, pressure) within safe operating bounds. IC Role / Device Role / Timing Role: Paired MAX9039BEBT-T units implement high/low thresholds using shared 1.23V reference for ratio-metric accuracy.

IC Role / Device Role / Timing Role: Comparator uses REF as threshold and VCC = 3.3V to generate clean 3.3V logic outputs. Use Value: Rail-to-rail output swing ensures full 0–3.3V swing compatible with CMOS input thresholds. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator + reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9038EBT+T | Same UCSP-6 package, identical 1.23V reference, but open-drain output (vs. push-pull) | Requires external pull-up for logic-high assertion; unsuitable for driving capacitive loads directly | Select MAX9038EBT+T only when level translation or wired-OR bus operation is required |
| TLV4041DBVR | Single comparator with 1.2V reference, SOT23-6 package, 55μA supply current, ±3mV offset | Higher quiescent current and wider offset reduce battery life and precision in low-threshold detection | Choose TLV4041DBVR if SOT23 footprint compatibility is mandatory and 15μA extra current is acceptable |
Compared with MAX9038EBT+T and TLV4041DBVR, the MAX9039BEBT-T uniquely combines push-pull output drive, lowest supply current (40μA), and tightest B-grade reference accuracy (±0.4%) in the smallest UCSP footprint-making it optimal for space- and power-critical battery monitoring.

FAQ
What is the reference voltage accuracy and temperature coefficient of the MAX9039BEBT-T?
The MAX9039BEBT-T features a 1.23V precision voltage reference with ±0.4% initial accuracy at +25°C and a temperature coefficient of 100ppm/°C over −40°C to +85°C. This B-grade specification ensures predictable drift in battery-monitoring applications where thermal gradients occur, and the reference remains stable under capacitive loads up to 4.7nF without external compensation.
Does the MAX9039BEBT-T have rail-to-rail input and output capability?
Yes, the MAX9039BEBT-T provides true rail-to-rail input operation with a common-mode range extending 250mV beyond both supply rails (VEE − 0.25V to VCC + 0.25V), and a push-pull output stage that swings fully from VEE to VCC while sourcing or sinking up to 8mA. This eliminates level-shifting circuitry when interfacing with diverse logic families or analog sensors.
What is the supply current consumption of the MAX9039BEBT-T at different operating voltages?
The MAX9039BEBT-T draws 40μA typical quiescent current at VCC = 5V and 40μA at VCC = 2.7V, per the B-grade electrical characteristics table. Dynamic supply current increases only marginally with switching frequency - reaching ~50μA at 100kHz - due to its optimized output stage that minimizes current surges during transitions, preserving battery life in duty-cycled systems.
How is the MAX9039BEBT-T pinout configured in the UCSP package?
The MAX9039BEBT-T uses a 6-bump UCSP package with top-side bumps labeled A1–A3 and B1–B3. Pin mapping is: A1 = VEE, A2 = OUT, A3 = VCC, B1 = IN+, B2 = IN−, B3 = REF. This layout matches the functional diagram in the datasheet and supports compact routing with minimal trace inductance, critical for noise immunity in sensitive comparator applications.
Can the MAX9039BEBT-T be used in window comparator configurations?
Yes, the MAX9039BEBT-T is well-suited for window comparators: two units can share the same REF pin to generate matched high/low thresholds, leveraging the 1.23V reference's low tempco (100ppm/°C) and tight initial tolerance (±0.4%) to maintain window integrity across temperature. The uncommitted IN− input allows flexible external resistor networks for precise trip-point setting without degrading reference accuracy.
