The SEL pin digitally limits the output current to 4A,
3A, or 1A without a change in sense resistor value
between the three modes.
The single count current-sense voltage has been
changed to 5mV. R1 required is now 40m
.
After the AlarmWarning() message, the charger is
not locked off. Subsequent ChargingVoltage() or
ChargingCurrent() commands allow the MAX1667
to resume the charge.
10) The Alert-Response address is 0x13 (0b00010011).
When upgrading a MAX1647 design, follow these rec-
ommended or required changes (part numbers refer to
Figure 3 of the MAX1647 data sheet):
1) Change R1 to 40m
(required).
2) Remove diodes D5 and D6, transistor Q1, and resis-
tor R6. Connect IOUT directly to BATT (recommend-
ed).
3) Remove the external +4.096V reference (recom-
mended).
4) Remove D6 (recommended). When doing this, also
place a small-signal diode in series with R7 and con-
nect it directly to the DC source (see D3 and R5 on
Figure 3 of the MAX1647 data sheet).
