3 Description

The INA236 device is a 16-bit digital current monitor

with an I2C/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 over/under current as well as over/under

voltage 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.
