MAX9611PMB1

MAX9611PMB1 Peripheral Module

Description

The MAX9611PMB1 peripheral module provides the necessary hardware to interface the MAX9611 currentsense amplifier with 12-bit ADC and op amp, along with the MAX5380 8-bit DAC, to any system that utilizes PmodK-compatible expansion ports configurable for I2C communication. The IC is configured with an external p-channel FET and a current-sense resistor to form a current-limiting circuit capable of handling currents up to 1A. An 8-bit DAC (U1) is used to set the currentlimit point programmatically by the host through the I2C bus. In addition to providing a programmable currentlimit function, the ADC within the IC measures the load current/voltage and the set-point voltage that can be read by the host through the I2C bus.

Refer to the MAX9611 IC data sheet for detailed information regarding operation of the IC.
