- Kernel driver ina3221
- =====================
- Supported chips:
- * Texas Instruments INA3221
- Prefix: 'ina3221'
- Addresses: I2C 0x40 - 0x43
- Datasheet: Publicly available at the Texas Instruments website
- http://www.ti.com/
- Author: Andrew F. Davis <afd@ti.com>
- Description
- -----------
- The Texas Instruments INA3221 monitors voltage, current, and power on the high
- side of up to three D.C. power supplies. The INA3221 monitors both shunt drop
- and supply voltage, with programmable conversion times and averaging, current
- and power are calculated host-side from these.
