Figure 5. CONFIG Register Format
SLEEP (Sleep Bit)
Writing SLEEP to logic 1 forces the ICs into Sleep
mode. Writing SLEEP to logic 0 forces the ICs to exit
Sleep mode. The power-up default value for SLEEP is
logic 0.
X (Don't Care)
This bit reads as either a logic 0 or logic 1. This bit cannot
be written.
ALRT (ALERT Flag)
This bit is set by the IC when the SOC register value
falls below the alert threshold setting and an interrupt is
generated. This bit can only be cleared by software.
The power-up default value for ALRT is logic 0.
Table 3. COMMAND Register Commands
ATHD (Alert Threshold)
The alert threshold is a 5-bit value that sets the state of
charge level where an interrupt is generated on the
ALRT pin. The alert threshold has an LSb weight of 1%
and can be programmed from 1% up to 32%. The
threshold value is stored in two ’s-complement form
(00000 = 32%, 00001 = 31%, 00010 = 30%, 11111 =
1%). The power-up default value for ATHD is 4% or 1Ch.
COMMAND Register
The COMMAND register allows the host processor to
send special commands to the IC. Valid COMMAND
register write values are listed as follows. All other
COMMAND register values are reserved. Table 3
shows COMMAND register commands.

The MAX17043/MAX17044 have a variety of configura-
tions, depending on the application. Table 4 shows the
most common system configurations and the proper
pin connections for each.
