Smart Module Series
The maximum input
voltage is 4.50 V.
If fuel gauge is not used,
connect these pins to
ground.
Externally pull this pin up
to LDO1_1V85 with a
47 kΩ resistor.
Supports 10 kΩ NTC
thermistor by default -
connect this pin to the
10 kΩ NTC thermistor.
If unused, connect it to
GND with a 10 kΩ
resistor.
Input voltage: 0–1.2 V.
If not used, keep it open.
Comment
50 Ω impedance.
