For example:
1- Let's assume you need to drive the ON_OFF*/WAKE* pad with a totem pole output of
a +3/5 V microcontroller (uP_OUT1):
2- Let's assume you need to drive the ON_OFF*/WAKE* pad directly with an ON/OFF
button:
Warning: It is recommended to set the ON_OFF*/WAKE* line LOW to
power on the module only after VBATT is higher than 3.20V.In case
this condition it is not satisfied you could use the HW_SHUTDOWN*
line to recover it and then restart the power on activity using the
ON_OFF*/WAKE* line. An example of this is described in the
following diagram.
After HW_SHUTDOWN* is released you could again use the ON_OFF*/WAKE* line to
power on the module.
