In sleep mode, the IC halts all operations, reducing
current consumption (below 1FA). After exiting sleep
mode, the IC continues normal operation. In sleep mode,
the IC does not detect self-discharge. If the battery
changes state while the IC sleeps, the IC cannot detect
it, causing SOC error. Wake up the IC before charging
or discharging.
To enter sleep mode, write MODE.EnSleep = 1 and:
1) Hold SDA and SCL logic-low for a period of t
2) Write CONFIG.SLEEP = 1. To wake up the IC, write
All registers must be written and read as 16-bit words;
8-bit writes cause no effect. Any bits marked X (don’t
care) or read only must be written with the rest of the
register, but the value written is ignored by the IC. The
values read from don’t care bits are undefined.
Calculate the register’s value by multiplying the 16-bit
word by the register’s LSb value, as shown in

CONFIG.SLEEP = 0. Other communication does not
wake up the IC. POR wakes up the IC.

The MAX17058 measures VCELL between the V
GND pins. The MAX17059 measures VCELL between the
CELL and GND pins. The register value is the average of
four ADC conversions. The value updates every 250ms
in active mode.
The ModelGauge algorithm calculates relative SOC,
automatically adapting to variation in battery size. The
upper byte least-significant bit has units of 1%. The
first update is available approximately 1s after POR.
Subsequent updates occur at variable intervals depending
on application conditions.
The MODE register allows the system processor to send
special commands to the IC (see
