INA233AIDGSR Description
The INA233AIDGSR device is a current, voltage and power monitor with I 2C, SMBus and PMBus compatible interfaces and with digital bus voltages from 1.8V to 5.0V. The device monitors and reports current, voltage and power values. The integrated power accumulator can be used for energy and average power consumption calculation. When the programmable calibration value, conversion time and average value are combined with the internal multiplier, the current value (in amperes) and the power value (in watts) can be read directly. The INA233AIDGSRcan sense current in the common-mode bus voltage range from 0V to 36V independent of the supply voltage. The device is powered by a single power supply from 2.7V to 5.5V and consumes a typical power supply current of 310 μ A under normal operating conditions. The device can be placed in low power standby mode, in which the typical working current is only 2 μ A. The device has a rated operating temperature range of-40 °C to + 125 °C and has up to 16 programmable addresses.
