ATmega16HVB/32HVB

Pack+ will therefore rise to the charger voltage for a short period before the C-FET is

enabled.

Battery voltage reached charger voltage.

25.3.3

Deep Under Voltage operation with Pre-charge FET

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 62.

25.3.4

Operation in Reset and Power off

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.
