* Maxim max9611/max9612 current sense amplifier with 12-bits ADC interface
|
||
|
|
|
||
|
|
Maxim max9611/max9612 is an high-side current sense amplifier with integrated
|
||
|
|
12-bits ADC communicating over I2c bus.
|
||
|
|
The device node for this driver shall be a child of a I2c controller.
|
||
|
|
|
||
|
|
Required properties
|
||
|
|
- compatible: Should be "maxim,max9611" or "maxim,max9612"
|
||
|
|
- reg: The 7-bits long I2c address of the device
|
||
|
|
- shunt-resistor-micro-ohms: Value, in micro Ohms, of the current sense shunt
|
||
|
|
resistor
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
&i2c4 {
|
||
|
|
csa: adc@7c {
|
||
|
|
compatible = "maxim,max9611";
|
||
|
|
reg = <0x7c>;
|
||
|
|
|
||
|
|
shunt-resistor-micro-ohms = <5000>;
|
||
|
|
};
|
||
|
|
};
|
||
|
|
|
||
|
|
This device node describes a current sense amplifier sitting on I2c4 bus
|
||
|
|
with address 0x7c (read address is 0xf9, write address is 0xf8).
|
||
|
|
A sense resistor of 0,005 Ohm is installed between RS+ and RS- current-sensing
|
||
|
|
inputs.
