BQ25120, BQ25121
SLUSBZ9B – AUGUST 2015 – REVISED MAY 2016
Typical Application (continued)
10.2.2.3.3 Program the Pre-charge/termination Threshold (IPRETERM)
According to Table 3, the RIPRETERM is 4990 Ω for 10% termination threshold. Therefore, connect a 4.99 kΩ
resistor between IPRETERM pin and GND.
10.2.2.3.4 TS Resistors (TS)
The voltage at TS is monitored to determine that the battery is at a safe temperature during charging. This device
uses JEITA temperature profile which has four temperature thresholds. Refer to Specifications for the detailed
thresholds number.
The TS circuit is shown in Figure 16. The resistor values can be calculated using Equation 1 and Equation 2.
