Texas Instruments INA231AIYFFT
- Part Number:
- INA231AIYFFT
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3251433-INA231AIYFFT
- Description:
- 28V, 16-bit, i2c output current/voltage/power monitor w/alert in wcsp
- ECAD Model:
-
- Datasheet:
- ina231
Description
The INA231 is a current-shunt and power monitor with a 1.8-V compliant I²C interface that features 16 programmable addresses. The INA231 monitors both shunt voltage drops and bus supply voltage. Programmable calibration value, conversion times, and averaging combined with an internal multiplier enable direct readouts of current in amperes and power in watts.
The INA231 senses current on buses that vary from 0V to 28 V, with the device powered from a single 2.7-V to 5.5-V supply, drawing 330 μA (typical) of supply current. The INA231 is specified over the operating temperature range of -40°C to 125°C.
Features
High- or low-side measurement
Bidirectional current/power monitor
Bus voltage sensing from 0 V to 28 V
High- or low-side sensing
Current, voltage, and power reporting
High accuracy:
-0.5% gain error (max)
50-μV offset (max)
Configurable averaging options
Programmable alert threshold
