Analog Devices Inc./Maxim Integrated MAX9017AEKA+TG0N

Overview

The MAX9017AEKA+TG0N from Maxim Integrated is a dual nanoPower comparator with integrated 1.236V ±1% precision reference, Beyond-the-Rails™ inputs (VEE −0.2V to VCC +0.2V), push-pull output stage, and guaranteed operation down to 1.8V supply. It draws only 1.2μA at 1.8V, features 4mV internal hysteresis, and delivers rail-to-rail output swing up to ±6mA - ideal for 2-cell battery monitoring in portable medical instruments and ultra-low-power telemetry systems.

For engineers reviewing the MAX9017AEKA+TG0N datasheet, MAX9017AEKA+TG0N pinout, MAX9017AEKA+TG0N application, or MAX9017AEKA+TG0N equivalent, key selection criteria include its A-grade reference accuracy, dual-channel push-pull output architecture, SOT23-8 package footprint, and validated performance across −40°C to +85°C in battery voltage supervision and ground-referenced sensing.

Technical Context

This device implements two independent comparators sharing a single precision bandgap reference. Its input stage supports common-mode voltages beyond supply rails by ±200mV, enabling direct sensing at ground or supply lines without level-shifting. The break-before-make push-pull output stage eliminates crowbar current surges during switching, reducing supply glitches and dynamic power consumption.

Internal 4mV hysteresis ensures clean transitions with slow-moving signals, while the 1.236V ±1% reference exhibits 40ppm/°C temperature coefficient and <30µV_RMS noise (10Hz–1kHz). Propagation delays are 6–11µs (VCC = 5V/1.8V), with rise/fall times of 1.6µs/0.2µs into 15pF load.

Key Specifications

Pinout & Package

MAX9017AEKA+TG0N is housed in an 8-pin SOT23 package (2.0mm × 2.1mm × 1.25mm), compatible with standard reflow profiles (260°C peak, 10s lead temp). Pin 1 is REF/INA− (1.236V reference output internally tied to comparator A inverting input); pins 5 and 8 are no-connect (N.C.).

The following parts are listed as comparable options for similar dual nanoPower comparator applications.

Compared with MAX9017BEKA+TG0N, the MAX9017AEKA+TG0N offers tighter reference accuracy (±1% vs. ±1.75%) and lower temperature drift, making it preferable for calibrated battery cutoff. Against TLV3692IDR, it trades 0.85µA higher I_CC for integrated reference and rail-exceeding inputs - reducing BOM count and PCB area in space-constrained designs.

FAQ

What is the reference voltage tolerance and temperature coefficient of the MAX9017AEKA+TG0N?

The MAX9017AEKA+TG0N features an A-grade internal reference rated at 1.236V ±1% at +25°C, with a guaranteed accuracy of ±2.5% over the full −40°C to +85°C operating range. Its temperature coefficient is 40ppm/°C, resulting in ≤±0.35% drift across temperature - verified in production testing and documented in the MAX9015–MAX9020 datasheet Rev 6.

Can the MAX9017AEKA+TG0N operate from a 1.8V supply while driving a 6mA load?

Yes, the MAX9017AEKA+TG0N is fully specified to operate at 1.8V supply and deliver rail-to-rail output swing with ±6mA loads. At VCC = 1.8V and ISINK = 1mA, VOL is guaranteed ≤300mV; at ISOURCE = 1mA, VOH is ≤300mV. These values scale predictably to 6mA per the typical curves in the datasheet, confirming robust drive capability even at minimum supply.

How does the Beyond-the-Rails™ input feature work in the MAX9017AEKA+TG0N?

The MAX9017AEKA+TG0N's Beyond-the-Rails™ inputs accept common-mode voltages from VEE −0.2V to VCC +0.2V - meaning it can accurately compare signals at 0V (ground) or slightly above VCC without damage or phase reversal. This is achieved via specialized input ESD protection diodes and biasing that remain functional beyond rail limits, enabling direct battery terminal sensing without external level-shifting circuitry.

Is the MAX9017AEKA+TG0N pin-compatible with other devices in the MAX9015–MAX9020 family?

The MAX9017AEKA+TG0N uses the same 8-pin SOT23 pinout as MAX9017BEKA+TG0N and MAX9018 variants, with identical pin functions (REF/INA−, INA+, INA−, VEE, N.C., OUTA, VCC, N.C.). However, it is not pin-compatible with MAX9019/MAX9020 (no reference) or MAX9015/MAX9016 (single-channel), as those use different pin configurations and package counts.

What is the maximum capacitive load the MAX9017AEKA+TG0N output can drive while maintaining specified propagation delay?

The MAX9017AEKA+TG0N output is characterized up to 15pF load capacitance, with tPD+ and tPD− specified at CL = 15pF. For loads exceeding 15pF, propagation delay increases linearly - e.g., tPD− rises from 6µs (CL = 15pF, VCC = 5V) to ~14µs at 100pF. Driving >100pF requires external buffer amplification to maintain timing integrity in high-speed applications.
