functional description
The bq2420x supports a precision Li-Ion or Li-Pol charging system suitable for single-cells with either coke or
graphite anodes. Figure 5 shows an application schematic and Figure 6 shows the typical charge profile.
temperature qualification (bq24200 and bq24201 only)
The bq24200 and bq24201 continuously monitors battery temperature by measuring the voltage between the
TS and VSS pins. A negative- or a positive-temperature coefficient thermistor (NTC, PTC) and an external
voltage divider typically develop this voltage (see figure 5). The bq24200 and bq24201 compare this voltage
against the internal V
(TS1)
and V
(TS2)
thresholds to determine if charging is allowed (see Figure 7). The
temperature sensing circuit is immune to any fluctuation in Vcc since both the external voltage divider and the
internal thresholds are referenced to Vcc.
Once a temperature outside the V
(TS1)
and V
(TS2)
thresholds is detected the bq24200 and bq24201 immediately
suspend the charge. The bq24200 and bq24201 suspend the charge by turning off the powerFET and holding
the timer value (i.e. timers are NOT reset). Charge is resumed when the temperature returns to the normal
range.
