CSD204MDMSOP10

The CSD204M can detect bus voltage and bidirectional current on a common-mode bus ranging from -5V to 65V, 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 CSD204L supports a bus voltage measurement range of -5V to 65V. Its -5V negative common-mode voltage capability allows the CSD204L to operate and measure below ground voltage, making it highly suitable for applications where the bus voltage may experience instantaneous negative voltage. The differential voltage range on the bus current shunt resistor of the CSD204L 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 CSD204M supports up to 16 I²C programmable addresses.
