MAX17048/MAX17049
Micropower 1-Cell/2-Cell Li+ ModelGauge ICs
VALRT Register (0x14)
This register is divided into two thresholds: Voltage
alert maximum (VALRT.MAX) and minimum (VALRT.
MIN). Both registers have 1 LSb = 20mV. The IC alerts
while VCELL > VALRT.MAX or VCELL < VALRT.MIN
(see Figure 11).
CRATE Register (0x16)
The IC calculates an approximate value for the average
SOC rate of change. 1 LSb = 0.208% per hour (not for
conversion to ampere).
VRESET/ID Register (0x18)
See Figure 12.
? ID is an 8-bit read-only value that is one-time pro-
grammable at the factory, which can be used as an
MSB (VALRT.MIN)—ADDRESS 0x14
MIN 7 MIN 6 MIN 5 MIN 4 MIN 3 MIN 2 MIN 1 MIN 0
identifier to distinguish multiple cell types in produc-
tion. Writes to these bits are ignored.
? VRESET[7:1] adjusts a fast analog comparator and
a slower digital ADC threshold to detect battery
removal and reinsertion. Set between 2.28V and
3.48V, 40mV to 80mV below the application’s empty
voltage, according to the desired reset threshold for
your application. If the comparator is enabled, the IC
resets 1ms after VCELL rises above the threshold.
Otherwise, the IC resets 250ms after the VCELL reg-
ister rises above the threshold.
? Dis. Set Dis = 1 to disable the analog comparator in
hibernate mode to save approximately 0.5 F A
