Port C is a 5-bit high voltage Open Drain bi-directional I/O port.
High voltage output to drive Charge/Discharge FET. For details, see
Filtered positive/negative input from external current sense resistor, used to by the Coulomb
Counter ADC to measure charge/discharge currents flowing in the battery pack. For details, see
”Coulomb counter – Dedicated fuel gauging Sigma-Delta ADC” on page
Unfiltered positive/negative input from external current sense resistor, used by the battery pro-
tection circuit, for over-current and short-circuit detection. For details, see
page
NV, PV1, PV2, PV3, and PV4 are the inputs for battery cells one, two, three and four, used by
the Voltage ADC to measure each cell voltage. For details, see
eral purpose 12-bit Sigma-Delta ADC” on page
Defines the source voltage level for the Charge FET driver. For details, see
146.
Input for detecting when a charger is connected. Defines the source voltage level for the Dis-
charge FET driver. For details, see
Reset input. A low level on this pin for longer than the minimum pulse length will generate a
reset, even if the clock is not running. The minimum pulse length is given in
228. Shorter pulses are not guaranteed to generate a reset. This pin is also used as debugWIRE
communication pin.
