The MAX9611PMB1# from Maxim Integrated Products is a peripheral module. It provides the necessary hardware to interface MAX9611 current sense amplifier with 12bit ADC, op amp and MAX5380 8bit DAC to any system that utilizes Pmod™-compatible expansion ports configurable for I?C 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 8bit DAC (U1) is used to set the current limit point programmatically by the host through the I2C bus. In addition to providing a programmable current limit 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. Typical applications include battery operated equipment, general power supply/monitoring applications, handheld devices and server backplanes.
