Typical values stated where TA = 25°C and VBAT = 59.2 V, min/max values stated where TA = -40°C to 85°C and VBAT = 4.7 V to 80 V (unless otherwise noted)(1)
||Internal cell balancing resistance(2)
||RDS(ON) for internal FET switch at VVC(n) - VVC(n-1) = 1.5V, 1 ≤ n ≤ 16, VBAT ≥ 4.7 V
(1) Operation with VBAT up to 80 V is supported when the charge pump is not in operation. Whenever the charge pump is in operation (in 5.5 V or 11 V mode), the maximum voltage on VBAT should be reduced to ensure the voltage on CP1, CHG, and DSG does not exceed their maximum specified voltage.
(2) Cell balancing must be controlled to limit the current based on the absolute maximum allowed current, and to avoid exceeding the recommended device operating temperature. This can be accomplished by appropriate sizing of the offchip cell input resistors and limiting the number of cells that can be balanced simultaneously.
