3.1 Turning ON the GE863-QUAD/PY

To turn on the GE863-QUAD/PY the pad ON# must be tied low for at least 1 second and then

released.

The maximum current that can be drained from the ON# pad is 0,1 mA.

A simple circuit to do it is:

NOTE: don't use any pull up resistor on the ON# line, it is internally pulled up. Using pull

up resistor may bring to latch up problems on the GE863-QUAD/PY power regulator and

improper power on/off of the module. The line ON# must be connected only in open

collector configuration.

NOTE: In this document all the lines that are inverted, hence have active low signals are

labeled with a name that ends with a "#" or with a bar over the name.

NOTE: The GE863-QUAD/PY turns fully on also by supplying power to the Charge pad

(provided there's a battery on the VBATT pads).

For example:
