107~19VDC input from AC adapter.
CHARGCL I 11 Enables Charger output.  This input is driven by an open drain
signal to set the charging current limit to a high (3 .5A max.) or
low (2A). The lower limit is set when the signal is low (switch on).
The system will generally set this signal low when the battery has
been discharged to a low level. The battery current sensor is built
into the charger circuitry. The resistance of the drain switch is
less than 1K
W.
Note, this signal sets the limit value of the charging current. The
CHARGFB and CHARGSP signals may restrict the charging
current to a lower level.
CHARGON I 12 This is a logic level signal, active high to enable the adapter
current output. This signal allows the system board to turn off the
charger output whenever the battery pack reports unsafe
conditions such as over temperature, error or no communication.
It may be used in response to any other detectable unsafe
