SY24655 is similar to INA226. Its supply voltage and pin definitions are therefore the same. Compared to INA226, SY24655 has two additional registers for configuring and calculating average power.

|
ti,shunt-gain:
|
|
description: |
|
|
Programmable gain divisor for the shunt voltage accuracy and range. This
|
|
property only applies to devices that have configurable PGA/ADCRANGE. The
|
|
gain value is used configure the gain and to convert the shunt voltage,
|
|
current and power register values when reading measurements from the
|
|
device.
|
|
|
|
For devices that have a configurable PGA (e.g. INA209, INA219, INA220),
|
|
the gain value maps directly with the PG bits of the config register.
|
|
|
|
For devices that have ADCRANGE configuration (e.g. INA238) a shunt-gain
|
|
value of 1 maps to ADCRANGE=1 where no gain divisor is applied to the
|
|
shunt voltage, and a value of 4 maps to ADCRANGE=0 such that a wider
|
|
voltage range is used.
|
|
|
|
The default value is device dependent, and is defined by the reset value
|
|
of PGA/ADCRANGE in the respective configuration registers.

ti,alert-polarity-active-high:
|
|
description: Alert pin is asserted based on the value of Alert polarity Bit
|
|
of Mask/Enable register. Default value is Normal (0 which maps to

|
active-low open collector). The other value is Inverted
|
|
(1 which maps to active-high open collector). Specify this property to set
|
|
the alert polarity to active-high.
