Voltage monitor, 3 channels, 0-26V I2C
- SKU: INA3221
The INA3221 is a three-channel, high-side current and bus voltage
monitor with an I2C- and SMBUS-compatible interface. The INA3221
monitors both shunt voltage drops and bus supply voltages, in addition
to having programmable conversion times and averaging modes for these
signals. The INA3221 offers both critical and warning alerts to detect
multiple programmable out-of-range conditions for each channel.
The
INA3221 senses current on buses that can vary from 0 V to 26 V. The
device is powered from a single 2.7-V to 5.5-V supply, and draws 350 µA
(typ) of supply current. The INA3221 is specified over the operating
temperature range of –40°C to +125°C. The I2C- and SMBUS-compatible
interface features four programmable addresses.
