maxim,max31875 (on i2c bus)

Vendor: Maxim Integrated Products

Description

Maxim MAX31875 Low-Power I2C Temperature Sensor.
Find the datasheet here:
https://datasheets.maximintegrated.com/en/ds/MAX31875.pdf

Properties

Properties not inherited from the base binding file.

Name

Type

Details

conversions-per-second

string

Number of temperature readings performed by the MAX31875 per second.
0.25 converions per second is the power-on reset configuration.

Default value: 0.25

Legal values: '0.25', '1', '4', '8'

extended-mode

boolean

When true, use 13-bit data format to allow for measuring
temperatures > 128°C

resolution

int

The number of bits used for each temperature sample.
A resolution of 10 bits takes 35ms to convert.
Each 1-bit increase doubles the conversion time.
Similarly, each 1-bit decrease halves the conversion time.
10 bits of resolution is the power-on reset configuration.

Default value: 10

Legal values: 8, 9, 10, 12

supply-gpios

phandle-array

GPIO specifier that controls power to the device.

This property should be provided when the device has a dedicated
switch that controls power to the device.  The supply state is
entirely the responsibility of the device driver.

Contrast with vin-supply.

vin-supply

phandle

Reference to the regulator that controls power to the device.
The referenced devicetree node must have a regulator compatible.

This property should be provided when device power is supplied
by a shared regulator.  The supply state is dependent on the
request status of all devices fed by the regulator.

Contrast with supply-gpios.  If both properties are provided
then the regulator must be requested before the supply GPIOS is
set to an active state, and the supply GPIOS must be set to an
inactive state before releasing the regulator.
