Voltage Adjust. Use a voltage-divider to set the VADJ voltage between 0 and V
REF
to adjust the
battery regulation voltage by ±5%. See
Setting the Voltage Limit
section.
VADJ
8
Thermistor Input. Connect a thermistor from THM to GND to set a qualification temperature
range. If unused, connect a 10k
resistor from THM to ground. See
Thermistor
section.
