Anticollapse Loop
The analog anticollapse loop operates so that the input voltage is monitored continuously and the charging
current is set by analog loop to maintain the defined input voltage.
Battery Temperature Measurement
The battery temperature is measured using an external NTC resistor. The measurement is enabled before the
charging starts and the temperature is constantly monitored during charging. If the battery temperature is outside
the valid range, the charging is gated; if the temperature returns inside the valid range, the charging continues. If
a battery dies, the battery temperature is monitored so that the charging does not start if the temperature is
outside the valid range. The gating of the charging can be disabled with an EPROM bit if needed.
The module is enabled if VBUS or an external charger is detected. An interrupt is always generated when the
battery temperature crosses the temperature limits in both directions. The interrupt generation can be masked if
needed.
Figure 13 shows the battery temperature measurement circuitry.
