The CSD203L can detect bus voltage and bidirectional current on a common-mode bus ranging from 0V to 36V, and output via an I²C™ or SMBus digital interface. Its programmable calibration values, conversion times, averaging, and built-in multiplier allow users to directly read current, bus voltage, temperature, and power values from registers. The differential voltage range on the bus current shunt resistor of the CSD203L is ±81.69mV or ±163.37mV, allowing for a wider range of shunt resistor values. The device is powered by a single supply voltage ranging from 2.7V to 5.5V, with a typical supply current of 340μA, and an operating temperature range of -40°C to 125°C. The CSD203L supports up to 16 I²C programmable addresses.
