The SQ52210 is a three-channel high-side monitor designed for accurate measurement of current and power, featuring an interface compatible with both I2C and SMBus protocols. It supports simultaneous monitoring of voltage across the shunt resistor and bus supply voltage, with programmable conversion times and signal averaging options. A user-programmable calibration register, along with an integrated scaling factor, allows direct output of current in amperes and power in watts. The device also includes programmable alert functions for each channel, providing both critical and warning thresholds to signal out-of-range conditions.

The SQ52210 measures current on bus voltages ranging from 0V to 32.76V, regardless of the device’s supply voltage. It supports a maximum common-mode voltage of up to 70V. Powered by a single supply between 2.7V to 5.5V, the device typically consumes 300μA of supply current. It is rated for operation across a temperature range of –40°C to +125°C and supports four programmable I2C-compatible addresses for flexible device configuration.
