THR INPUT AND JEITA SETTINGS 

The THR input of the 

ADP5061

 evaluation board is equipped 

with two 10 kΩ resistors (R9 and R12) and jumper J10. When 
using an actual Li-Ion NTC thermistor terminal, configure the 
board according to Figure 7. 
1.

 

Remove the R9 resistor. 

2.

 

Connect the Li-Ion battery NTC thermistor to the screw 
terminal, J2, at Pin 4.

Figure 7. THR Input Evaluation Setup. 

Evaluating THR Input Using Typical Board Setup 

To evaluate the THR input using the typical board setup, do the 
following: 
1.

 

Set the V

IN

 supply voltage to 5.0 V. 

2.

 

Set V

ISO_B

 to 3.9 V. 

3.

 

Set the charge current setting to 750 mA using the GUI. 

4.

 

Set V

IN

 input current limit to 1500 mA. 

5.

 

Enable charging (EN_CHG = high). 

6.

 

Measure current to ISO_Bx, value should be 750 mA. 

7.

 

Remove jumper J10 from the board. 

8.

 

The 

THR-pin status

 indicator on the GUI must show 

BatCool

9.

 

Enable JEITA by setting EN_JEITA bit high in functional 
settings register, Register 0x08. 

10.

 

Measure current to ISO_Bx. Charging current must now 
be half of the fast charge current setting. 

11.

 

Reinstall Jumper J10 to the board. 

12.

 

The charge current must return to the full charge current 
setting value. 

13.

 

The 

THR-pin status

 indicator must show 

Thermistor OK

Evaluating THR Input Using a Trimmer Resistor 

It is possible to evaluate the resistance thresholds according to 
the JEITA Li-Ion battery temperature levels with a 50 kΩ trimmer 
resistor. Use the setup shown in Figure 7; however, connect the 
trimmer resistor to the THR input of the J2 screw terminal 
instead of the battery thermistor.  
1.

 

Set the V

IN

 supply voltage to 5.0 V. 

2.

 

Set V

ISO_B

 to 3.9 V. 

3.

 

Set the charge current setting to 750 mA using the GUI. 

4.

 

Set the V

IN

 input current limit to 1500 mA. 

5.

 

Enable charging (EN_CHG = high). 

6.

 

Enable JEITA by setting EN_JEITA bit high in functional 
settings register, Register 0x08. 

7.

 

Change the trimmer resistor setting to evaluate the JEITA 
thresholds. The THR input resistance thresholds are 
specified in the 

ADP5061

 data sheet. 

8.

 

The 

THR-pin status

 indicator in the GUI must show 

BatCold

BatCool

Thermistor OK

BatWarm

, or 

BatHot

 

when adjusting the trimmer resistance from 50 kΩ to 0 Ω.
