description: | | ||
The PAC1921 is a power/current monitoring device with an analog output | ||
and I2C/SMBus interface. | ||
Datasheet can be found here: | ||

shunt-resistor-micro-ohms: | ||
description: | ||
Value in micro Ohms of the shunt resistor connected between | ||
the SENSE+ and SENSE- inputs, across which the current is measured. | ||
Value is needed to compute the scaling of the measured current. | ||
|
||
label: | ||
description: Unique name to identify which device this is. | ||
|
||
read-integrate-gpios: | ||
description: | ||
READ/INT input pin to control the current state of the device, either in | ||
the INTEGRATE state when driven high, or in the READ state when driven low. | ||
When not connected the pin is floating and it can be overridden by the | ||
INT_EN register bit after asserting the READ/INT_OVR register bit. | ||
