General Description
The MX884 targets power management applications
where high noise immunity and low cost are primary
requirements.
high
monitoring systems.
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.
