Deep Under Voltage operation with Pre-charge FET
Operation in Reset and Power off
6. The total cell voltage has reached 5V. DUVR mode is disabled and the C-FET can be
7. Battery voltage reached charger voltage.
If a charger without pre-charge functionality is used, the Pre-charge FET will provide the current
path and the pre-charge resistor will limit the charge current during charging of deeply over-dis-
charged cells. After reaching sufficient battery voltage it is safe to turn on the Charge FET to
increase the charge current. Deep Under Voltage Operation with Pre-charge FET is supported
through PC5, which is a high voltage open drain pin. For configuration and usage of this pin, see
”High Voltage I/O Ports” on page
In reset and power-off the C-FET and D-FET will be automatically turned off. Safety is remained
by active pulling OC/OD hard to ground.
fully enabled. DUVR mode should be disabled before the C-CFET is enabled. VFET and
Pack+ will therefore rise to the charger voltage for a short period before the C-FET is
enabled.
