DESCRIPTION
Setting this bit to “1” forces the device to go into a sleep condition. This turns off both FET outputs, the cell balance
outputs and the voltage regulator. This also resets the CFET, DFET, and CB7ON:CB1ON bits. The SLEEP bit is
automatically reset to “0” when the device wakes up. This does not reset the AO3:AO0 bits.
Writing a “1” to this bit turns on the VMON circuit. Writing a “0” to this bit turns off the VMON circuit. As such, the
microcontroller has full control of the operation of this circuit.
Reserved for future expansion.
Setting this bit to “1” turns on the charge FET.
Setting this bit to “0” turns off the charge FET.
This bit is automatically reset in the event of a charge overcurrent condition, unless the automatic response is disabled
by the DENOCC bit.
Setting this bit to “1” turns on the discharge FET.
Setting this bit to “0” turns off the discharge FET.
This bit is automatically reset in the event of a discharge overcurrent or discharge short circuit condition, unless the
automatic response is disabled by the DENOCD or DENSCD bits.
