Micropower 1-Cell/2-Cell Li+ ModelGauge ICs
HIBRT Register (0x0A)
To disable hibernate mode, set HIBRT = 0x0000. To
always use hibernate mode, set HIBRT = 0xFFFF (see
Figure 9).
? ActThr (active threshold): If at any ADC sample
|OCV-CELL| is greater than ActThr, the IC exits
hibernate mode. 1 LSb = 1.25mV.
? HibThr (hibernate threshold). If the absolute value of
CRATE is less than HibThr for longer than 6min, the IC
enters hibernate mode. 1 LSb = 0.208%/hr.
CONFIG Register (0x0C)
? RCOMP is an 8-bit value that can be adjusted
to optimize IC performance for different lithium
chemistries or different operating temperatures.
Contact Maxim for instructions for optimization. The
POR value of RCOMP is 0x97.
? SLEEP forces the IC in or out of sleep mode if
Mode.EnSleep is set. Writing 1 forces the IC to enter
sleep mode, and 0 forces the IC to exit. The POR
value of SLEEP is 0.
? ALSC (SOC change alert) enables alerting when
SOC changes by at least 1%. Each alert remains until
MSB (HibThr)—ADDRESS 0x0A
STATUS.SC is cleared, after which the alert automati-
cally clears until SOC again changes by 1%. Do not
use this alert to accumulate changes in SOC.
? ALRT (alert status bit) is set by the IC when an alert
occurs. When this bit is set, the ALRT pin asserts
low. Clear this bit to service and deassert the ALRT
pin. The power-up default value for ALRT is 0. The
STATUS register specifies why the ALRT pin was
asserted.
? ATHD (empty alert threshold) sets the SOC threshold,
where an interrupt is generated on the ALRT pin and
can be programmed from 1% up to 32%. The value is
(32 - ATHD)% (e.g., 00000b à 32%, 00001b à 31%,
00010b à 30%, 11111b à 1%). The POR value of
ATHD is 0x1C, or 4%. The alert only occurs on a fall-
ing edge past this threshold.
