BAL_CTL
Address Name Type D7 D6 D5 D4 D3 D2 D1 D0
0x02 BAL_CTL R/W BAL_6 BAL_5 BAL_4 BAL_3 BAL_2 BAL_1
Defaults: 0 0 0 0 0 0 0 0
BAL_n: Balance control for cell n. When set, turns on balancing transistor for cell n. Setting of two adjacent
balance controls is not permitted. If two adjacent balance controls are set, neither cell balancing transistor will be
turned on. However, the BAL_n bits will retain their values.
CONFIG_1
Address Name Type D7 D6 D5 D4 D3 D2 D1 D0
0x03 CONFIG_1 R/W I_THRESH I_COMP_POL I_AMP_CAL I_GAIN
Defaults: 0 0 0 0 0
I_THRESH: Current comparator threshold. Sets the threshold of the current comparator as follows:
I_THRESH Comparator threshold
0x0 25 mV
0x1 50 mV
0x2 75 mV
0x3 100 mV
0x4 125 mV
0x5 150 mV
0x6 175 mV
0x7 200 mV
0x8 225 mV
0x9 250 mV
0xA 275 mV
0xB 300 mV
0xC 325 mV
0xD 350 mV
0xE 375 mV
0xF 400 mV
I_COMP_POL: Current comparator polarity select. When 0, trips on discharge current (SENSEP > SENSEN).
When 1, trips on charge current (SENSEP < SENSEN).
I_AMP_CAL: Current amplifier calibration. When 0, current amplifier reports SENSEN with respect to VSS.
When 1, current amplifier reports SENSEP with respect to VSS. This bit can be used for offset cancellation as
described under OPERATIONAL OVERVIEW.
