| 31 | Description |
| 32 | ----------- |
| 33 | |
| 34 | The INA219 is a high-side current shunt and power monitor with an I2C |
| 35 | interface. The INA219 monitors both shunt drop and supply voltage, with |
| 36 | programmable conversion times and filtering. |
| 37 | |
| Guenter Roeck | dc92cd0 | 2012-05-12 11:33:11 -0700 | [diff] [blame] | 38 | The INA220 is a high or low side current shunt and power monitor with an I2C |
| 39 | interface. The INA220 monitors both shunt drop and supply voltage. |
