Product Details

The MAX9611PMB1 peripheral module provides the necessary hardware to interface the MAX9611 current-sense amplifier with 12-bit ADC and op amp, along with the MAX5380 8-bit DAC, to any system that utilizes Pmod™-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 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.
Refer to the MAX9611 IC data sheet for detailed information regarding operation of the IC.
