Product details
Overview
The MAX40003ANS02+T from Analog Devices is a nanoPower, inverting-input comparator with integrated 0.2V factory-trimmed reference, open-drain output, and ultra-low 500nA supply current. It operates from 1.7V to 5.5V, supports input voltages from 0.1V to 5.5V (independent of supply), and is specified over –40°C to +125°C for automotive-grade reliability. It is used in battery-critical signal monitoring circuits such as low-voltage battery charge-state detection in portable medical devices.
For engineers reviewing the MAX40003ANS02+T datasheet, MAX40003ANS02+T pinout, MAX40003ANS02+T application, or MAX40003ANS02+T equivalent, key selection considerations include its inverting topology, 0.2V internal reference accuracy (±12mV at +25°C), 9µs propagation delay under 100mV overdrive, open-drain output requiring external pullup, and operation in both 4-bump WLP (0.73mm × 0.73mm) and SOT23 packages.
Technical Context
This device implements an inverting-input comparator architecture with internal temperature-compensated voltage reference and high-impedance inputs that remain functional even when VCC/REF = 0V. Its input stage allows VIN to exceed VCC by several volts-unlike conventional comparators limited by ESD diode clamping-enabling robust level-shifting in mixed-supply systems.
The open-drain output supports rail-to-rail interfacing with logic operating up to 5.5V, while built-in 8mV (typ) hysteresis ensures noise immunity without external components. Internal filtering provides high RF immunity, and the BiCMOS process enables stable performance across –40°C to +125°C with <32mV input offset voltage max over temperature.
Key Specifications

IC Role / Device Role / Timing Role: Inverting comparator interfaces with thermistor divider network; output pulls low to enable fan control logic. Use Value: –40°C to +125°C rating supports under-dash mounting; open-drain output simplifies interface with 5V automotive logic. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7031YKAR | Noninverting input, 1.6V–6.5V supply, 650nA IQ, 0.2V reference not integrated - requires external reference | Suitable for noninverting threshold detection only; lacks factory-trimmed 0.2V reference | Select when noninverting logic is required and board space permits external reference |
| MAX40013ANS09+T | Inverting input, open-drain, same WLP package, but 0.9V internal reference and higher supply current (600nA typ) | Used where higher reference voltage improves SNR against noise; less suitable for sub-0.3V thresholds | Select when 0.9V threshold better matches system signal range and tighter reference tolerance is needed |
Compared with TLV7031YKAR and MAX40013ANS09+T, the MAX40003ANS02+T uniquely combines inverting topology, ultra-low 500nA current, and factory-trimmed 0.2V reference in a 0.73mm × 0.73mm WLP - making it optimal for compact, battery-constrained designs requiring precise low-voltage detection.

FAQ
What is the function of the IN pin on the MAX40003ANS02+T?
The IN pin is the inverting input of the comparator. When the voltage applied to IN exceeds the internal 0.2V reference voltage (VREF-INT), the open-drain output (OUT) is pulled low. This behavior makes the MAX40003ANS02+T ideal for generating active-low interrupt signals in microcontroller-based systems where a falling edge triggers action.
Does the MAX40003ANS02+T require an external pullup resistor on the OUT pin?
Yes, the MAX40003ANS02+T features an open-drain output and requires an external pullup resistor (e.g., 100kΩ to 3.3V) to establish a defined high state. Without it, the OUT pin remains floating when not actively sinking current. This design enables voltage-level translation and wired-OR configurations, which are essential in multi-source interrupt systems.
What is the accuracy of the internal 0.2V reference in the MAX40003ANS02+T over temperature?
The internal 0.2V reference in the MAX40003ANS02+T is specified as 188mV to 212mV at +25°C (±12mV), and 174mV to 226mV over the full –40°C to +125°C range (±26mV). This factory-trimmed accuracy eliminates the need for external calibration or trimming components, ensuring consistent trip-point performance across environmental conditions.
Can the MAX40003ANS02+T operate with input voltages higher than its supply voltage?
Yes - the MAX40003ANS02+T supports input voltages from 0.1V to 5.5V independent of VCC/REF, and absolute maximum ratings allow IN to reach up to +6V. This capability stems from its innovative input-stage architecture without ESD diode clamping to VCC, enabling direct interfacing with higher-voltage sensors or legacy analog signals without external level-shifting circuitry.
Is the MAX40003ANS02+T suitable for automotive applications?
Yes, the MAX40003ANS02+T is fully specified over –40°C to +125°C and qualified for automotive use. Its BiCMOS process, integrated hysteresis, RF-immune design, and AEC-Q200-aligned reliability make it appropriate for cabin electronics, battery monitoring modules, and other under-hood or interior automotive subsystems requiring long-term stability and low power.
