MAX44269

1.3mm x 1.3mm, Low-Power

Dual Comparator

General Description

Features

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.

S Ultra-Low Power Consumption

 0.5µA per Comparator

S Ultra-Small 1.3mm x 1.3mm WLP Package

S Guaranteed Operation Down to V = 1.8V

S Input Common-Mode Voltage Range Extends

200mV Beyond-the-Rails

S 6V Tolerant Inputs Independent of Supply

S Open-Drain Outputs

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 struc-

ture and a unique output stage that limits supply current

surges while switching. This design also minimizes over-

all 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.

S Internal Filters Enhance RF Immunity

S Crowbar-Current-Free Switching

S Internal Hysteresis for Clean Switching

S No Output Phase Reversal for Overdriven Inputs
