Current Sense Amplifier
|
||
|
|
=======================
|
||
|
|
|
||
|
|
When an io-channel measures the output voltage from a current sense
|
||
|
|
amplifier, the interesting measurement is almost always the current
|
||
|
|
through the sense resistor, not the voltage output. This binding
|
||
|
|
describes such a current sense circuit.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : "current-sense-amplifier"
|
||
|
|
- io-channels : Channel node of a voltage io-channel.
|
||
|
|
- sense-resistor-micro-ohms : The sense resistance in microohms.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- sense-gain-mult: Amplifier gain multiplier. The default is <1>.
|
||
|
|
- sense-gain-div: Amplifier gain divider. The default is <1>.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
sysi {
|
||
|
|
compatible = "current-sense-amplifier";
|
||
|
|
io-channels = <&tiadc 0>;
|
||
|
|
|
||
|
|
sense-resistor-micro-ohms = <20000>;
|
||
|
|
sense-gain-mul = <50>;
|
||
|
|
};
