General Description

The MX884 targets power management applications

where high noise immunity and low cost are primary

requirements.

Its integrated 10-bit ADC provides

high

resolution,

making

it

ideal

for

current

monitoring systems.

The MX884 enables digital

power management, in which a microcontroller can

readily monitor the current in a system and perform

other control functions in power systems and motion

control products.

The MX884 converts a small voltage developed

across an external “current” sense resistor to a 10-

bit digital output. It features a wide common mode

input supply voltage range of 3V to 60V and easily

interfaces to most microcontrollers. The design is

simple yet cost-effective, requiring very few external

components, making it especially suitable for high

volume applications.
