LTC4067
ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the full operating
temperature range (Note 3), otherwise specifications are at TA = 25°C. Note 2 unless otherwise noted, VIN = 5V, VBAT = 3.7V,
VILIM0 = 0V, VILIM1 = 0V, RPROG = 2k, RCLPROG = 2k, VOVI = 0V, VNTC = VIN/2.
