Analog Devices Inc./Maxim Integrated MAX9017AEKA/V+T

Overview

MAX9017AEKA/V+T from Maxim Integrated is a dual nanoPower comparator with integrated 1.236V ±1% reference, Beyond-the-Rails™ inputs (VEE −0.2V to VCC +0.2V), 1.2μA supply current at 1.8V, push-pull output stage, and 4mV internal hysteresis - designed for precision threshold detection in 2-cell battery monitoring systems.

For engineers reviewing the MAX9017AEKA/V+T datasheet, MAX9017AEKA/V+T pinout, MAX9017AEKA/V+T application, or MAX9017AEKA/V+T equivalent, this page delivers verified electrical specs, package mapping, real-world use cases, and validated alternative options for ultra-low-power sensing and battery management designs.

Technical Context

The MAX9017AEKA/V+T implements a rail-to-rail input stage enabling operation beyond supply rails by 200mV, paired with a crowbar-current-free push-pull output capable of ±6mA drive. Its internal 1.236V ±1% reference is trimmed at +25°C and exhibits 40ppm/°C temperature coefficient over −40°C to +85°C.

It features fixed 4mV input-referred hysteresis to suppress noise-induced oscillation, no phase reversal under overdrive, and guaranteed operation from 1.8V to 5.5V supply. Propagation delays are 7µs (high-to-low) and 11µs (low-to-high) at 1.8V with 15pF load.

FAQ

What is the reference voltage accuracy and temperature stability of MAX9017AEKA/V+T?

The MAX9017AEKA/V+T features a factory-trimmed 1.236V reference with ±1% initial accuracy at +25°C and ±2.5% total variation over −40°C to +85°C. Its temperature coefficient is 40ppm/°C, resulting in ±0.34mV drift across the full operating range. This stability enables reliable threshold detection in battery monitoring and sensor applications without external calibration.

Does MAX9017AEKA/V+T support operation below 1.8V supply?

No, MAX9017AEKA/V+T is guaranteed to operate only down to 1.8V supply voltage per its Absolute Maximum Ratings and Electrical Characteristics tables. Operation below 1.8V may result in undefined behavior, including failure to assert correct output states or reference regulation. For sub-1.8V applications, consider alternative comparators explicitly rated for lower VCC.

Can the REF pin of MAX9017AEKA/V+T be used as a high-precision voltage source for external circuitry?

Yes, the REF pin of MAX9017AEKA/V+T can source or sink up to ±100nA while maintaining ±1% accuracy. For loads exceeding 100nA or requiring lower output impedance, buffer the REF output with a low-input-bias-current op amp such as the MAX4162. Avoid routing high-current traces near REF to prevent coupling-induced errors.

What is the maximum capacitive load the push-pull output of MAX9017AEKA/V+T can drive reliably?

The push-pull output of MAX9017AEKA/V+T is characterized up to 15pF load in propagation delay testing. While it can drive larger capacitances, tPD increases significantly beyond this point - e.g., tPD+ rises from 11µs to ~40µs at 100pF (VCC = 1.8V). For loads >30pF, add a series resistor to damp ringing and verify timing margins in final layout.

Is MAX9017AEKA/V+T qualified for automotive applications?

Yes, MAX9017AEKA/V+T carries the /V suffix, indicating AEC-Q100 Grade 3 qualification (−40°C to +85°C ambient). It meets automotive reliability requirements for temperature cycling, humidity, and mechanical stress. The device is suitable for cabin monitoring, battery management, and non-safety-critical control functions in passenger vehicles.
