ELECTRICAL CHARACTERISTICS (continued)

(Circuit of Figure 1. VDCIN = VCSSP = VCSSN = 18V, VBATT = VCSIP = VCSIN = 12V, VDD = 3.3V, ACIN = PGND = GND, LDO = DLOV,

VMAX = IMAX = REF, CLDO = 1µF, CDHIV = 0.1µF, CREF = 1µF, TA = 0°C to +85°C. Typical values are at TA = +25°C, unless other-

wise noted.)
