ti,tmp435 (on i2c bus)

Vendor: Texas Instruments

Note

An implementation of a driver matching this compatible is available in drivers/sensor/ti/tmp435/tmp435.c.

Description

These nodes are “tmp435” bus nodes.

Texas Instruments TMP435 temperature sensor

Properties

Properties not inherited from the base binding file.

Name

Type

Details

external-channel

boolean

External temperature measurement is enabled

resistance-correction

boolean

Resistance correction feature for the external
temperature channel. If not enabled then conversion
is faster but with lower accuracy.

beta-compensation

int

Beta Compensation Configuration, see Table 8
from TMP435 data sheet, some common values.
0x0f, Automatically selected range 7 (beta > 27.0) or
Automatically detected diode connected sensor
0x07, Manually disabled beta correction
Default is common value for general purpose transistors.

Default value: 15

Legal values: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15

friendly-name

string

Human readable string describing the sensor. It can be used to
distinguish multiple instances of the same model (e.g., lid accelerometer
vs. base accelerometer in a laptop) to a host operating system.

This property is defined in the Generic Sensor Property Usages of the HID
Usage Tables specification
(https://usb.org/sites/default/files/hut1_3_0.pdf, section 22.5).

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.
