silergy,sy24561 (on i2c bus)

Vendor: Silergy Corp.

Note

An implementation of a driver matching this compatible is available in drivers/fuel_gauge/sy24561/sy24561.c.

Description

SY24561 is a simple gas gauge IC for single cell lithium-ion (Li+) batteries in handheld
and portable equipment.

SY24561 senses battery terminal voltage and use the proprietary algorithm to calculate the
corresponding State of Charge (SOC). Comparing with conventional voltage-based gauge which
translates terminal voltage directly to SOC, the advanced algorithm in SY24561 shows great
advantage in SOC accuracy. SY24561 can be classified as advanced voltage-based gauge without
current sensor and the SOC accuracy will not degrade with time. Temperature of the battery
pack is measured by the host microcontroller and feed to SY24561 through the I2C interface.
SY24561 can automatically compensate temperature, load variation and battery age.

Properties

Properties not inherited from the base binding file.

Name

Type

Details

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.
