max
=4.2 V
The external power supplies at least
2.5 A current to VBAT.
VBAT voltage sampling pin
This pin must be connected to VBAT;
otherwise, the module cannot start up.
V
norm
=1.8 V, I
max
= 50 mA
Used only for voltage-level translation.
Leave this pin open if unused.
18, 30, 35, 38, 41, 43 - 45, 47, 73, 77 - 92
Ensure that all GND pins are
grounded.
Active low; used to reset the module.
