Feature Description (continued)

9.3.14 External NTC Monitoring (TS)

The I2C interface allows the user to easily implement the JEITA standard for systems where the battery pack

thermistor is monitored by the host. Additionally, the bq2416xx provides a flexible, voltage based TS input for

monitoring the battery pack NTC thermistor. The voltage at TS is monitored to determine that the battery is at a

safe temperature during charging. The bq24160, bq24160A, bq24161B, bq24163, and bq24168 enable the user

to easily implement the JEITA standard for charging temperature while the bq24161 only monitors the hot and

cold cutoff temperatures and leaves the JEITA control to the host. The JEITA specification is shown in.

Figure 13. Charge Current During TS Conditions

To satisfy the JEITA requirements, four temperature thresholds are monitored; the cold battery threshold (TNTC <

0°C), the cool battery threshold (0°C < TNTC < 10°C), the warm battery threshold (45°C < TNTC ≤ 60°C) and the

hot battery threshold (TNTC > 60°C). These temperatures correspond to the VCOLD, VCOOL, VWARM, and VHOT

thresholds. Charging is suspended and timers are suspended when VTS < VHOT or VTS > VCOLD. When VWARM >

VTS > VHOT, the battery regulation voltage is reduced by 140mV from the programmed regulation threshold.

When VCOLD > VTS > VCOOL, the charging current is reduced to half of the programmed charge current.

The TS function is voltage based for maximum flexibility. Connect a resistor divider from DRV to GND with TS

connected to the center tap to set the threshold. The connections are shown in Figure 20. The resistor values are

calculated using the following equations:
