Description
General part information
INA236 Series
The INA236 device is a 16-bit digital current monitor with an I 2C/SMBus-compatible interface that is compliant with a wide range of digital bus voltages such as 1.2 V, 1.8 V, 3.3 V, and 5.0 V. The device monitors the voltage across an external sense resistor and reports values for current, bus voltage, and power.
The INA236 features programmable ADC conversion times and averaging. The device also has a programmable calibration value with an internal multiplier that enables direct readouts of current in amperes and power in watts. The device monitors the bus voltage present on the IN– pin and can alert on overcurent and undercurrent conditions as well as overvoltage and undervoltage conditions. High input impedance while in current measurement mode allows use of larger current sense resistors needed to measure small value system currents.
The INA236 senses current on common-mode bus voltages that can vary from –0.3 V to 48 V, independent of the supply voltage. The device operates from a single 1.7-V to 5.5-V supply, drawing a typical supply current of 300 µA in normal operation. The device can be placed in a low-power standby mode where the typical operating current is 2.2 µA.
