1.3mm x 1.3mm, Low-Power Dual Comparator

Industry's Smallest Dual Comparator Solution

Product Details

The MAX44269 is an ultra-small and low-power dual comparator ideal for battery-powered applications such as cell phones, notebooks, and portable medical devices that have extremely aggressive board space and power constraints. The comparator is available in a miniature 1.3mm x 1.3mm, 9-bump WLP package, making it the industry’s smallest dual comparator.

The IC can be powered from supply rails as low as 1.8V and up to 5.5V. It requires just 0.5µA of typical supply current per comparator. It has a rail-to-rail input structure and a unique output stage that limits supply current surges while switching. This design also minimizes overall power consumption under dynamic conditions. The IC has open-drain outputs, making it suitable for mixed voltage systems. The IC also features internal filtering to provide high RF immunity. It operates over a -40°C to +85°C temperature range.

Key Features

  • Ultra-Low Power Consumption
    • 0.5µA per Comparator
  • Ultra-Small 1.3mm x 1.3mm WLP Package
  • Guaranteed Operation Down to VCC = 1.8V
  • Input Common-Mode Voltage Range Extends 200mV Beyond-the-Rails
  • 6V Tolerant Inputs Independent of Supply
  • Open-Drain Outputs
  • Internal Filters Enhance RF Immunity
  • Crowbar-Current-Free Switching
  • Internal Hysteresis for Clean Switching
  • No Output Phase Reversal for Overdriven Inputs

Description

The MAX44269 evaluation kit (EV kit) is a fully assembled and tested PCB that evaluates the MAX44269 dual comparator in a 1.3mm x 1.3mm wafer-level package (WLP). The EV kit circuit can be easily configured by installing shunts and changing a few components to support multiple comparator application circuits, such as window detector, jack detection, relaxation oscillator, pulse-width modulated (PWM) generator, logic-level translator, or power-on-reset circuit. The EV kit provides 0603 component PCB pads for ease of evaluation. The EV kit circuit operates from a +1.8V to +5.5V VCC supply.
