Analog Devices Inc./Maxim Integrated MAX9063EUK+T

Overview

MAX9063EUK+T from Analog Devices is a nanoPower single comparator with integrated 0.2V reference, inverting input configuration, open-drain output, and 5-pin SOT23 package. It operates from 1.0V to 5.5V supply, draws ≤700nA quiescent current, features −0.3V to +5.5V input voltage range independent of V_CC, and supports −40°C to +85°C operation - ideal for low-voltage battery monitoring in portable medical devices.

For engineers reviewing the MAX9063EUK+T datasheet, MAX9063EUK+T pinout, MAX9063EUK+T application, or MAX9063EUK+T equivalent, key selection criteria include its inverting-input topology, internal 0.2V reference accuracy (±12mV hysteresis, ±15mV total trip-point error), 15µs propagation delay, ultra-low supply current scalability across 1V–5.5V rails, and compatibility with microcontroller I/O pins requiring open-drain logic-level translation.

Technical Context

The MAX9063EUK+T implements an inverting-input comparator architecture with a temperature-compensated internal 0.2V reference, enabling direct low-threshold detection without external components. Its input stage maintains high impedance even when V_CC = 0V, supporting power-gating schemes in energy-harvesting systems.

It uses an open-drain output stage requiring an external pull-up, allowing level-shifting between disparate supply domains (e.g., 1.8V comparator rail driving a 3.3V microcontroller input). Propagation delay remains stable at 15µs over −40°C to +85°C with ±100mV overdrive, and input bias current stays below 15nA across the full input voltage range.

FAQ

What is the function of the IN pin on the MAX9063EUK+T?

The IN pin on the MAX9063EUK+T is the inverting input terminal. When the voltage at IN exceeds the internal 0.2V reference, the open-drain output pulls low; when IN falls below 0.2V, the output floats high (requiring external pull-up). This configuration enables active-low threshold detection, commonly used for battery low-voltage alerts and reset generation in the MAX9063EUK+T.

Does the MAX9063EUK+T require an external reference voltage?

No, the MAX9063EUK+T does not require an external reference voltage. It integrates a factory-trimmed 0.2V internal reference with ±15mV total trip-point error over −40°C to +85°C. This eliminates external components and simplifies design for fixed-threshold applications such as brown-out detection - a key differentiator of the MAX9063EUK+T versus reference-less comparators.

Can the MAX9063EUK+T operate from a 1.0V supply?

Yes, the MAX9063EUK+T is fully specified to operate from 1.0V to 5.5V supply voltage. At V_CC = 1.0V, it maintains ≤700nA max supply current, 15µs propagation delay, and valid logic levels at the open-drain output (V_OL ≤ 0.2V at 50µA sink). This 1.0V minimum enables direct use with depleted alkaline cells and sub-1.2V microcontrollers - a core capability of the MAX9063EUK+T.

What is the purpose of the dual GND pins (Pins 2 and 3) on the MAX9063EUK+T?

Pins 2 and 3 on the MAX9063EUK+T are both connected to the internal ground plane. The dual GND configuration improves thermal dissipation and reduces ground loop inductance, which enhances noise immunity in sensitive analog monitoring applications. Both pins must be soldered to the PCB ground plane - this mechanical and electrical redundancy is part of the SOT23 package design for the MAX9063EUK+T and is not a functional differentiation between pins.

Is the MAX9063EUK+T pin-compatible with other devices in the MAX9060–MAX9064 family?

No, the MAX9063EUK+T is not pin-compatible with MAX9060/MAX9061 (external reference) or MAX9062/MAX9064 (noninverting input or push-pull output) in the same SOT23 package. While all share the 5-pin SOT23 outline, the functional assignment differs: MAX9063EUK+T assigns Pin 4 to IN (inverting) and Pin 5 to OUT (open-drain), whereas MAX9062EUK+ swaps IN to Pin 4 (noninverting) and MAX9064EUK+ uses Pin 5 for push-pull OUT. Board layout must be verified per exact part number - MAX9063EUK+T requires dedicated routing.
