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 into 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, which makes it especially suitable for
high volume applications.
