ELECTRICAL CHARACTERISTICS (continued)
(VDCIN = VCSSP = VCSSN = 18V, VBATT = VCSIP = VCSIN = 12V, VREFIN = 3.0V, VVCTL = VICTL = 0.75 ✕ REFIN, CELLS = 2.0V,
ACIN = 0, CLS = REF, VBST - VLX = 4.5V, GND = PGND = 0, CLDO = 1µF, LDO = DLOV, CREF = 1µF; pins CCI, CCS, and CCV are
compensated per Figure 1a; TA = -40°C to +85°C, unless otherwise noted.) (Note 1)
