The SQ52210R1 is a three-channel, high-side current and power monitor with an I2C- and SMBUS-compatible interface. The SQ52210R1 monitors both shunt voltage drops and bus supply voltages, in addition to having programmable conversion times and averaging modes for these signals. Programmable calibration value combined with an internal multiplier enable direct readouts of current in amperes and power in watts. The SQ52210R1 offers both critical and warning alerts to detect multiple programmable out-of-range conditions for each channel.
