MAX9611PMB1 Datasheet, PDF (1/9 Pages) Maxim Integrated Products – Programmable Current Limit Up to 1A

19-6328; Rev 0; 5/12
MAX9611PMB1 Peripheral Module
General Description
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
PmodK-compatible expansion ports configurable for
I²C communication. The IC is configured with an exter-
nal 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 informa-
tion regarding operation of the IC.
